LIGHT COMMERCIAL BUILDING SOLUTION
Light Commercial Building
Solution
INTRODUCTION
Description
The Light Commercial Building Solution (LCBS) is a family of
control devices designed to meet the comfort control
requirements of commercial buildings of small to medium size.
Commercial buildings typical of this market include but are not
limited to office buildings, retail stores, light manufacturing
facilities, restaurants, schools, churches, theaters, super
markets, grocery stores, and banks.
These buildings typically use some combination of single
zone air handling units, heat-pumps, zoned air handling units,
variable air volume systems, fan coil units, unit ventilators,
and/or perimeter heating to maintain the building’s comfort
levels. In addition, lighting control, equipment on-off
scheduling, and data collection may be required of the control
system.
Products Included
Light Commercial Building Solution devices utilize the
LonWorks® communication protocol for open systems
network communications. The controllers may also be used
for stand-alone control applications.
The Light Commercial Building Solution includes thermostats
and a number of application specific controllers (Excel 10) to
directly address typical mechanical systems. The advantage
of application specific controllers is use of a sophisticated and
efficient control strategy matched to the mechanical
equipment functions, standardizing the control processes, and
minimizing the effort required to configure and maintain the
system insuring consistent performance.
LCBS also includes a selection of Building Manager and
general purpose controllers (Excel 15) to address the need for
custom applications and to handle alarm reporting, data
collection and reporting, and operator interface
communications.
Operator interface to a LCBS may be with an easy to use
command display unit, LONSTATION™ workstation software
installed in a personal computer, or by internet access.
The system is configured using LONSPEC™ software installed
in a personal computer. LONSPEC™ simplifies system
configuration by letting the user select the desired control
options while most networking functions are done “behind the
scene”.
Specialized applications of LCBS are available as
RapidZone™ for zoning systems and LonStat™ for
thermostat only solutions.
Control Applications
Typical Light Commercial Building Applications:
• Single zone air handling unit thermostat control for up to 3
stages of heat and 3 stages of cooling.
• Single zone air handling unit control for up to 4 stages or
modulating heating and 4 stages or modulating cooling
with integrated economizer control.
• Heat pump air handling unit control for up to 4
compressors (heating and cooling) and 4 stages of
auxiliary/emergency heat and integrated economizer
control.

Floating Control⎯Refers to Series 60 Modulating Control of
a valve or damper. Floating Control utilizes one digital
output to drive the actuator open, and another digital
output to drive it closed.
FTT⎯Free Topology Transceiver.
HVAC⎯Heating Ventilation and Air Conditioning.
HYD⎯Hydronic Unit. (German acronym)
7
NEC⎯National Electrical Code; The body of standards for
safe field-wiring practices.
NEMA⎯National Electrical Manufacturers Association; The
standards developed by an organization of companies
for safe field wiring practices.
Network Management Node⎯A LONWORKS® node that is
responsible for configuring the network, installing the
nodes, binding the network variables between nodes
and general network diagnostics.
Network Object—See Object
Network Time Master⎯A network time master will be the
only device sending out the time/date. All other network
devices will use the time/date from the network time
master (even if they have their own real-time clock).
Network time master is chosen/configured from
LONSPEC™ and remains unchanged until re configured,
even in the event of a failure on the network time
master. (The Excel 15 W7760C can not be the network
time master.)

LIGHT COMMERCIAL BUILDING SOLUTION
Network Time Scheduler⎯The network time scheduler
sends out current and next state (occupied, unoccupied
or standby) and time until the next change of state
(TUNCOS) to all of its control loops based on the
configured schedules.
RapidLink—RapidLink™ is an RS232 and telephone line
compatible serial device that allows any host (PC) with
an RS 232 or Modem interface (and the necessary
driver software) to communicate with a LonWorks®
network.
Network Variables⎯A class of variables defined in Neuron C
that allow communication over the LONWORKS® network
to other nodes on the network. For example; An output
network variable in one node can be bound to the
corresponding input network variable(s) in other
node(s). Changing the value of the output network
variable in one node causes the new value to be
automatically communicated to the bound input network
variable(s) in other node(s). When an input network
variable is updated, an nv_update_occurs event is
posted at the receiving node(s) so that the application
program can take action based on the change. A
network management node that explicitly reads and/or
writes the network variable can also poll network
variables. Network variables can contain one data field
(one or two bytes) or multiple data fields (a structure).
RCD⎯Remote Communication Device; For the Building
Management System, this is a piece of hardware that is
functionally compatible to an SLTA and provides access
directly to the LONWORKS® Bus.
Node⎯A Communications Connection on a network; An
Excel 15 or Excel 10 Controller is one node on the
LONWORKS® Bus network.
Reset⎯The reset of a control loop varies depending upon the
type of control loop being reset. A reset for a thermostat
loop or a control loop changes the setpoint and the
algorithm in the energy saving direction. A reset for a
start/stop loop causes the digital output to go to the
inactive state before returning to its normal scheduled
state.
RIO⎯Excel 10 Remote I/O Device; Additional inputs and
outputs that can be configured for use by an Excel 15
W7760A or W7760C.
NV⎯Network Variable; An Excel 15 or Excel 10 parameter
that can be viewed or modified over the LONWORKS®
Bus network.
RTC⎯Real-time clock.
Object—Also referred to as control object or network object.
A single control algorithm with multiple input, output,
setpoints, and/or configuration parameters. Each XL10
application specific controller is a single object. Each
start/stop loop, control loop, and logic function in an
XL15 controller is a unique object.
PC⎯An Personal Computer with Pentium processor capable
of running Microsoft® Windows™.
Plant Controller⎯A device that can be used to monitor and
control HVAC equipment and other miscellaneous loads
in a distributed network.
Proportional Control⎯A control algorithm or method in
which the final control element moves to a position
proportional to the deviation of the value of the
controlled variable from the setpoint.
RTD⎯Resistance Temperature Detector; Refers to a type of
temperature sensor whose resistance output changes
according to the temperature change of the sensing
element.
RTU - Roof Top Unit; typically refers to a CVAHU built as a
single unit designed to be installed on a rooftop. Other
types of AHU’s are also built for roof top mounting.
Schedule⎯The structure that defines the occupancy states,
setpoints and the time of the changes between these
states.
SLTA⎯Serial LONTALK® Adapter; A serial interface between
the EIA-232 (serial port on a PC) and a LONWORKS®
Bus used to adapt transformer-coupled Echelon
messages.
SNVT⎯Standard Network Variable Type.
Proportional Integral (PI) Control⎯A control algorithm that
combines the proportional control and the integral reset
control algorithms. Integral reset virtually eliminates
offset by gradually shifting the controlled output in the
direction that brings the controlled variable back to the
setpoint.
TOD⎯Time-Of-Day; The scheduling of Occupied and
Unoccupied times of operation.
TUNCOS⎯Time Until Next Change Of State is a command
that can be sent to other controllers.
UV⎯See Unit Vent below.
Proportional Integral Derivative (PID) Control⎯A control
algorithm that enhances the PI control algorithm by
adding a component that is proportional to the rate of
change (derivative) of the deviation of the controlled
variable. PID compensates for system dynamics and
allows faster control response rate reset.
Unit Vent - Unit Ventilator (UV). A specialized AHU designed
to control high rates of ventilation as defined by
ASHRAE (Cycle I, II, or III).
VA⎯Volt Amperes; A measure of electrical power output or
consumption as applies to an ac device.
PWM⎯Pulse Width Modulated output; Allows analog
modulating control of equipment using a digital output
on the controller.

LIGHT COMMERCIAL BUILDING SOLUTION
Fig. 1 depicts the options available in the XL15A architecture.
The XL15A - LONSTATION™ solution offers the most
comprehensive LCBS solution. Network management
functions including scheduling, alarm handling, and dial-out
are performed by one or more Excel 15 W7760A Building
Managers (XL15A). All Excel10 application specific
controllers, T7350 and T7300F/Q7300H thermostats, Excel
15 W7760C Plant Manager, NX VFD, CXS AND CXL variable
frequency drives are supported by the W7760A Building
Manager. LONSTATION™ provides a cost effective, user
friendly operator interface.
See Table 3 for a complete list of devices supported and a
comparison of architecture features.
The system is configured using ZL7760A LONSPEC™ software
configuration tool.
Local and remote system monitoring is performed using
ZL7762A LONSTATION™ Software Monitoring and Graphics
software.
NOTE: The W7760B Building Manager is not supported in
the XL15A architecture and should not be used with
the W7760A Building Manager. While both the
W7760A and W7760B may coexist on the same
LONWORKS® bus, they do not support each other
and network functions may conflict if implemented in
both devices.
• Each W7760A supports a maximum of 20 analog and 20
digital user configured alarms. User configured alarms can
be configured for any analog or digital point in the system.
The maximum number of user configured alarms are 80
analog and 80 digital.
• Each W7760A will support a maximum of 16 Trend Logs. A
trend log is a single analog or digital point. A tend log can
be configured to use any point in the system. The
maximum number of trend logs is 64.
• Each W7760A will support a maximum of 15 Run Time
logs. A run time log may be configured for any single digital
point in the system. The maximum number of run time logs
is 60
• Each W7760A will support a maximum of 20 Bypass Logs.
A bypass log may be configured for any control object
bypass state. The maximum number of bypass logs is 80.
The T7300F/Q7300H thermostats can schedule a maximum
of 4 XL10 controllers, W7760C Plant Controller start-stop and
control loops, and other T7300F/Q7300Hs whereas the T7350

Networking Considerations
NETWORK CONSTRAINTS
The maximum number of devices on a LCBS LONWORKS®
bus is 120. This does not include LONTALK® adapters. The
maximum number of devices on a subnet segment is 60. If
more than 60 devices are used on a network, a Q7740A or B
repeater is required.
The recommended maximum LONWORKS® bus cable length
of a network segment is 9,200 feet (2,800 meters) with a
Q7740 repeater and 4,600 feet (1,400 meters) without a
repeater. The cable wire gage network topology will also
determine the maximum cable length that can be used.
The maximum number of W7760A Building Managers on a
sub-network is 4.
The maximum number of W7761A RIO devices is 3 per
W7760A and/or C.
In an XL15A solution further limitations on the number of
devices on a bus may result from alarm handling and data
sharing requirements.
• Each W7760A will support a maximum of 20 nodes
(W7760C, XL10 controllers, T7350 and T7300F/Q7300H
thermostats) for device internal alarms. Refer to Excel 15
W7760A Building Manager Application Guide 74-2969 for
alarm data.
• The maximum number of devices with internal alarm
reporting is 84 (4 W7760A plus 4 X 20 external = 84).
Additional 120 devices can be used. However, only 84
devices can be configured to report internal alarms.
11
The T7300F/Q7300H has only two Occupied and
two Unoccupied settings per day, no standby settings, uses a 7 day schedule with no temporary or
holiday schedules, and does not support adaptive
intelligent recovery in W7760C control loops and
XL10 controllers.
The T7350 has four settings (occupied, unoccupied, or standby) per day, uses a eight day schedule with a maximum of 10 holidays.
Alarm Handling
All alarm reporting and logging is done by one or more
W7760A Building Managers on the subnetwork. It requires
that each device to be alarmed be mapped to a W7760A.
Each W7760A will support a maximum of 20 other network
devices for alarm reporting. Devices that are not mapped to a
W7760A will not have alarms reported.
The W7760A Building Manager is configured to route alarms it
processes. The alarms can be configured to be ignored (Do
Nothing) or sent to any combination of dial-out to remote
LONSTATION™, sent to local LONSTATION™ and S7760A
Command Display, and/or log to the W7760A alarm log. See
Excel 15 W7760A Building Manager System Engineering (742969) for complete details on alarm handling.
S7760A COMMAND DISPLAY
The S7760A Command Display module can be configured to
display data from a maximum of 270 network objects. Each
LCBS network device is a network node object. In addition
each individual start-stop loop, control loop, and logic loop
configured in a W7760A or W7760C is a network object. Each
W7760A can be configured for as many as 15 network objects
(node + 8 start-stop + 6 control). Each W7760C can be
configured for as many as 51 network objects (node + 8 startstop + 10 control + 32 logic). The S7760A will support a
maximum of 4 W7760A Building Manager node objects, a
maximum of 10 W7760C Plant Controller node objects, and
any combination of Excel10 application specific controller
objects and Excel 15 control objects, not exceeding the limit of
270 network objects total.
74-3679—1
LIGHT COMMERCIAL BUILDING SOLUTION
NOTE: Few control objects from a W7760A or C are configured for display in a S7760A Command Display.
The S7760A Command Display module can be configured to
display alarm information from a W7760A Building Manager.
To display the alarm data, the W7760A node object must be
configured in the S7760A.
DATA SHARING
Refer to section “LonSpec Data Sharing” on page 38.
Configuring data sharing in LONSPEC™ is primarily done as
the individual controllers are already configured and requires
no additional action by the user. However, the use of standard
network shared points such as Outside Air Temperature and
Economizer Enable must be configured using the “Refer
Points” screen. See “Refer Points Applications” on page 40.
The LONSPEC™configuration screen “Refer Points” sorts the
available destination points based on the source point. The
sorting is based on the LonWorks® Standard Network
74-3679—1
12
Variable Type (SNVT) which may include many controller
variables that are very different in function. Refer to “Appendix
A - Refer Points Tables” on page 43 for a complete listing of
appropriate points for data sharing.
The W7760A Building Manager limit of scheduling a
maximum of 20 network devices can be circumvented using
“Refer Points” to share the schedule data to additional
devices. See “Time of Day Scheduling” on page 40.
When using a single wall module with more than one Excel 10
controller, it is necessary to use “Refer Points” to share the
wall module data from the source controller to the destination
controller(s).
Data sharing for W7751 VAV terminal unit applications
requires very specific attention to the application
requirements. Refer to Excel 10 W7751B,D,D,F,H,J Variable
Air Volume Controller Application Guide 74-2949 for specific
application details and “XL10 VAV Terminal (W7751)” on
page 39 for specific information on data sharing.

Networking Considerations
Fig. 2 depicts the options available in the XL15B Solution
architecture.
The XL15B architecture utilizes the internet to access the
LCBS system. The W7760B performs the network
management functions and is a secure web server providing
multi-user access to the system operating data, alarm and
trend logs, and schedules using Microsoft® Internet Explorer
(6.0 or higher) web browser.
The W7760B Building Manager supports:
• W7760C&D Plant Controllers
• W7750A,B,C CVAHU controller
• W7751B,D,F,H,J VAV II controllers and Smart Actuators
• W7753A Unit Ventilator controller
• Q7300H Communicating sub-base for T7300
• T7350 Communicating sub-base
• W7761A Remote Input Output Device
• W7762A,B Hydronic Device
• W7763C Cold Ceiling Device
• W7752D,E,F,G,J Fan Coil Unit
The recommended maximum LONWORKS® bus cable length
of a network segment is 9,200 feet (2,800 meters) with a
Q7740 repeater and 4,600 feet (1,400 meters) without a
repeater. The cable wire gage network topology will also
determine the maximum cable length that can be used.
The maximum number of W7760B Building Managers on a
sub-network is 1.
The maximum number of W7761A RIO devices is 3 per
W7760C. You can use an RIO device on the network that is
not associated with an W7760C strictly for monitoring the
inputs. There will be no output control for that device.
CAUTION
The S7760A Command Display will not support
reading or changing schedules nor will it support
alarm handling.
The S7760A supports only W7760A Building Manager
for scheduling and alarm handling. These functions
are not available when using a W7760B Building
Manager.
The S7760A can be used to read controller data and change
setpoints and execute commands. The constraints are the
same as those described for the XL15A solution, although,
there will be no W7760A Building Manager in the mix of
network objects.See page 11.
The W7760B will recognize and list other LONMARK®
compliant devices including third party devices on the
LONWORKS® bus but will not access them to read or write
data. Following are the LCBS devices that are not supported:
• ZL7762A LONSTATION™
• W7760A Building Manager
• S7760A (CD2) Command Display
• Q7760A SLTA
• RapidLink™
• W7790A RF Gateway
• XFL521 4-Digital Input Output Device
CAUTION
The W7760A Building Manager is not supported in
the XL15B architecture and must not be used with
the W7760B Building Manager.
While both the W7760A and W7760B may coexist on
the same LONWORKS® bus, they do not support each
other. It might result in conflicting of network functions
if implemented in both devices. See Table 3 for a
complete list of devices supported and a comparison
of architecture features.
The W7760B Building Manager is configured using internal
software tools. The remaining system devices are configured
using ZL7760A LONSPEC™ software configuration tool.
74-3679—1
NETWORK CONSTRAINTS
The maximum number of devices on a LCBS LONWORKS®
bus is 120 excluding LONTALK® adapters. The maximum
number of devices on a subnet segment is 60. If more than 60
devices are used on a network, a Q7740 repeater is required.
14
The W7760B Building Manager is a web server. Precautions
must be taken to insure appropriate LAN, WAN, and/or
internet security to protect the server from unauthorized
access.
WARNING
Failure to provide adequate internet security will
result in unauthorized access to the W7760B
Building Manager with severe consequences.
ALARM HANDLING
All alarm handling is executed by the W7760B Building
Manager.
Critical alarms are e-mailed to designated recipients.
The W7760B Building Manager supports multiuser access for
operators.
The W7760B does not support the S7760A Command
Display. Alarms cannot be routed to the W7760A.
Alarm data is accessible by internet if the user has access
authorization.
Configuration Considerations
LONSPEC™ (ZL7760A) is required to configure the supported
controllers in XL15B solution. Since LONSPEC™ is used to
configure all LCBS control devices, the user must exercise
care not to add devices that are not supported by the W7760B
to the network.
In addition, Excel 15B can be a network interface when
performing the following functions from LONSPEC™:
• Downloading all XL 10 and XL 15 devices' configurations.
• Performing online functions like device diagnostics and
calibration.
• Performing Device Discovery
• Commission and configuration of Excel 15B from
LONSPEC™.
• Upload or download Excel 15B configuration like alarms,
trends, schedules, and DLC loads from/to LONSPEC™.
LIGHT COMMERCIAL BUILDING SOLUTION
Refer to LONSPEC™ online help or LONSPEC™ User’s Guide
(form 74-2937).
Critical alarms can be configured to send e-mail annunciation
to designated recipients.
Initial setup of the W7760B requires a PC running Windows®
Hyper Terminal VT100 emulation that needs to be directly
connected to the serial port of the W7760B.
A maximum of 500 user defined alarms can be configured.
The scheduling, alarm handling, DLC, and trend logging are
configured using the W7760B Building Manager internal
configuration capability and LAN, WAN, or internet access.
The W7760B Building Manager does scheduling for all
supported devices on the LONWORKS® Network.

Fig. 3. RapidZone Solution Architecture
Fig. 3 depicts the options available in the RapidZone
architecture. Refer to the RapidZone Solution Application
Guide (74-3449) for a detailed description.
RapidZone consists of the ZL7751A software configuration
tool and is a subset of LCBS, designed specifically to meet the
requirements of the zoned air handling systems market. The
application uses the W7760C,D to control the air handling
unit(s) and W7751J to control the individual zones.
RapidZone supports a maximum of 10 air handling units each
with a maximum of 18 zones. The total number zones is
limited by the network maximum of 120 devices.
The W7760A Building Manager is optional. It may be used to
support scheduling and alarm handling. One W7760A may be
used to schedule a maximum of 4 zoning units and associated
zones. A single W7760A manages alarms for 1 W7760C RTU
74-3679—1
16
Controller and 18 W7751J Zone Controllers. The number of
W7760As required in a system is determined by the number
of RTU’s that must have alarm reporting. A maximum of 10
W7760A’s can be used on a RapidZone LONWORKS® bus.
The term RTU used throughout the RapidZone documentation
includes all the W7760C, CVAHU and Q7300 devices used in
zoning applications.
See Table 3 for a complete list of devices supported and a
comparison of architecture features.
Networking Considerations
The ZL7751A RapidZone Configuration tool can be directly
connected to the LonWorks® bus or connected via modem.
Refer to LonWorks® for LCBS - Networking Considerations
(form 74-2865).
LIGHT COMMERCIAL BUILDING SOLUTION
Configuration Considerations
The maximum number of devices on a LCBS LONWORKS®
bus is 120 excluding LONTALK® adapters.
A RapidZone solution may have a maximum of 10 W7760A
Building Managers, 10 W7760C Plant Managers (RTU
controllers), and 18 W7751H,J Smart actuators for every
W7760C. The maximum number of RTUs (any combination of
W7760C, W7750, Q7300) on the network cannot exceed 50.
Ensure that it does not exceed the total sub-network limit of
120 devices.
A Q7760A Repeater is required if the number of devices
exceeds 60 or if the bus cable length exceeds the maximum
allowable segment length.
ZL7762A LONSTATION™ monitoring software can be used
locally (direct connect) or remotely using a modem.
If a RapidZone configuration is to be imported into a
LONSPEC™ project that needs to be included in an XL15A
architecture, the maximum number of XL15A’s in the
RapidZone project is 10. However, when restored into
LonSpec only the first four XL15A's can be modified. In order
to be able to modify all W7760A's on the network through
LONSPEC™, the total number of W7760A's configured in
RapidZone must be limited to four.
If a RapidZone configuration is to be imported into a
LONSPEC™ project to be included in an XL15B architecture,
no W7760A’s can be used. Scheduling and alarm handling
must be configured with the W7760B Building Manager.
In both cases if S7760A Command Displays are to be used
they should be configured in the LONSPEC™ project and not in
RapidZone.

Fig. 4. LonStat Solution Architecture.
A LonStat solution consist of T7300F commercial
programmable thermostats with Q7300H communicating subbase configured with ZL7300A LonStat configuration and
monitoring software. A LonStat solution is used in the
traditional commercial thermostat market when a
communicating thermostat is required. LonStat does not
support any other device. LONWORKS® compatible devices
can reside on the same LONWORKS® bus but ZL7300A
LonStat software will not recognize them.
17
T7300F/Q7300H thermostats do no support mechanical
system alarms such as high or low limits, fan failure, or dirty
filter. T7300F/Q7300H diagnostic alarms are reported when
ZL7300 LonStat is used to monitor the specific thermostat in
alarm.
Key advantages of using LonStat solution when compared to
a traditional free standing commercial programmable
thermostat installations are:
• Current temperatures and setpoints can be checked
remotely with LonStat connected directly or remotely.
• Setpoints, time, schedules, and bypass can be changed
with LonStat connected direct or remotely.
74-3679—1
LIGHT COMMERCIAL BUILDING SOLUTION
Configuration Considerations
• With master time keeping, all thermostats maintain the
same time. Changing the master time keeper will update all
other thermostats within one minute.
• With master scheduling, multiple thermostats can be
“zoned” to maintain the same schedule. Changing the
schedule of a single thermostat changes the schedule for
all thermostats in the zone.With a discharge air sensor
installed, mechanical system troubleshooting can be done
remotely.
ZL7300 LonStat does not create a database. It must be
connected to the LONWORKS® bus directly or remotely by
modem. LonStat reads all configuration and operating data
directly from the thermostat. Changes made with LonStat are
downloaded to the thermostat, no record of the configuration
is retained on the PC. Since no LonStat database exists, a
LonStat solution cannot be restored to LONSPEC™.
Networking Considerations
LonStat and LONSTATION™ can be used to monitor a LonStat
solution both locally and remotely.
ZL7300A LonStat will communicate with only one thermostat
at a time.
The T7300F/Q7300H thermostat/sub-base has no
configurable alarms. Internal diagnostic alarms are displayed
in LonStat and LONSTATION™ only when the thermostat is
selected for monitoring.
See Table 3 for a complete list of devices supported and a
comparison of architecture features.

Fig. 5. Unconfigured CVAHU Architecture
Fig. 5 depicts the options available in the Unconfigured
CVAHU solution architecture.
The Unconfigured CVAHU Solution architecture provides a no configuration XL10 constant volume air handling unit
solution (use it directly out of the box). The W7750A,B,C
controllers are the only control devices supported in this
option. Monitoring is not supported as part of this solution.
Each unconfigured W7750 controller provides the control
functions of a T7300 thermostat. The bypass and setpoint
inputs if used, will work individually for the W7750 to which it is
connected.
The Unconfigured CVAHU solution is a simple cost effective
alternative to programmable thermostats especially when
night setback is required for multiple air handling units running
on the same schedule. This solution uses a simple wall
module without the complexity of a programmable thermostat,
simplifying operation for the user.
Since no configuration programming is required for the
W7750’s the cost of installing the network is offset by lower
labor cost.
The Unconfigured CVAHU solution does not require the
installer to be knowledgeable of direct digital control system
operation. Simply install the controllers, wire them, turn on the
power, and the job is done.
The factory default configuration for all models of the W7750
controller sets digital input 1 as a time clock input and digital
input 2 as Schedule Master. Placing a jumper across digital
input 2 causes the Schedule Master controller to broadcast
the occupancy mode. W7750 controllers that do not have the
jumper will automatically follow the schedule of the one that
does. Only one W7750 on the LONWORKS® bus can be
designated as the Schedule Master.
WARNING
Downloading to a W7750 CVAHU controller from
any configuration tool overwrites the factory
default settings and the automatic binding
capability is lost and cannot be restored.
The W7750 controller factory default configuration
settings must be accepted for all functions. Refer to
Excel 10 W7750A,B,C Application Engineering
manuals for complete details on factory default
configuration.
See Table 3 for a complete list of devices supported and a
comparison of architecture features.

Networking Considerations
• Control Functions:
— 8 start-stop loops
— 6 PID control loops
— 8 logic functions
All devices must be connected to the LONWORKS® FTT-10
bus.
A maximum of 120 W770 CVAHU controllers can be
connected to the network.
Zoning for multiple schedules can be created by adding
multiple networks each with it’s own time clock and master
scheduler jumper installed on one and only one W7750.
XL15B W7760B BUILDING MANAGER
The W7760B provides network management plus internet
web server functions. The W7760B is configured with internal
tools using Microsoft® Internet Explorer version 5.5 or higher.
Configuration Considerations
For a complete description refer to the documents listed for
W7760B in “Applicable Literature” on page 5.
No configuration is required. The Unconfigured CVAHU
solution uses the factory defaults.
• Physical Inputs and Outputs - None
The factor defaults for the Excel 10 W7750 CVAHU controllers
includes an algorithm that binds all controllers without the
Schedule Master input (digital input 2) to the one on the
network that does have the input jumpered. A time clock is
connected to the Time Clock input (digital input 1). The
scheduled occupancy state of the Schedule Master W7750 is
then shared to all others on the network.

The practical limit to the number of LONTALK® adapters
connected to a single network is 3: one directly connected to a
PC running LONSTATION™, another directly connected to a PC
running LONSPEC™, and one more connected remotely by a
modem to a PC running either LONSPEC™, or LONSTATION™.
Multiple directly connected PCs’ running either LONSPEC™ or
LONSTATION™ can result in data collisions leading to
communication failures.
Configuration Tools
The following are the three software configuration tools that
can be used to configure LCBS solutions:
LONSPEC™ (ZL7760A)
LONSPEC™ is the general purpose configuration tool used to
configure all LCBS network devices. LONSPEC™ is required to
configure XL15A and XL15B solutions. LONSPEC™ can be
used to monitor systems if no automatic dialing is required.
RAPIDZONE (ZL7751A)
RapidZone is an application driven configuration tool used to
configure W7760C Plant Manager, W7750A,B,C and T7300F/
Q7300H single zone RTU, W7751J Smart Actuator, W7760A
Building Manager, and S7760A Command Display for
commercial zoning applications. Device configuration is
automatic based on application data entered into the tool.
RapidZone projects with 10 or less W7760A Plant Managers
can be restored to LONSPEC™. RapidZone can be used to
monitor RapidZone systems if support for automatic dialing is
not required.
NOTE: LONSPEC™ can only configure the first four W7760A
Controllers on the network.
LONSTAT™ (ZL7300A)
LonStat™ is an application driven configuration and
monitoring tool used in projects that are comprised exclusively
of T7300F/Q7300H commercial programmable thermostats.
LonStat can be used only to configure the thermostats and
monitor thermostat data. No alarm reporting is supported.

APPLICATION STEPS
Refer to Table 3 LCBS Architecture Comparison for a brief
comparison of W7760A and W7760B Building Manager
capabilities.
Overview
The application steps shown in Table 4 are planning
considerations for engineering a Light Commercial Building
Solution. These steps are guidelines intended to aid
understanding: selection of appropriate control devices,
selection of appropriate operator interface devices and
software, LONWORKS® bus arrangement choices, power
requirements, network device configuration options, and
system startup and commissioning.

6
System Startup.
The XL15 controllers (W7760A,C) are used for custom
applications such as mechanical room control, variable
volume air handling units, specialized air handling systems,
lighting control, and equipment scheduling.
Step 1. Plan the System
Review the plans and specifications, system requirements
documentation, sales estimates, and/or any other documents
defining control system operation, user interface functions,
and data management requirements to determine the LCBS
architecture best suited for the project.
The Light Commercial Building Solution (LCBS) was developed
to address the HVAC control requirements typically found in
small to medium sized commercial buildings. For large
complex buildings, the EXCEL 5000 Open system provides
an appropriate solution.
When planning the system layout, consider potential
expansion possibilities to allow for future growth. Planning is
very important to enable addition of HVAC systems and
controllers in future projects.
The first consideration in selecting the architecture is what
monitoring and data gathering requirements exist. This
selection will determine the Building Manager that needs to be
used, if any. LONSTATION™ is used to monitor XL15A,
RapidZone, and LonStat™ solution architectures.
The XL15B solution is monitored with Microsoft® Internet
Explorer and requires a local area network (LAN), wide area
network (WAN), or internet connection.
WARNING
Do not install the W7760A and W7760B Building
managers on the same network. Both devices may
co-exist on the same network, but scheduling,
alarm handling, and logging are configured with
different tools (probability of data conflict is high).
LONSPEC™ supports both the W7760A and W7760B.
LONSPEC™ also uses W7760B as a network interface
to connect online. W7760B has internal configuration
settings and does not support the W7760A.
74-3679—1
Select the controllers that are supported by the application.
Excel10 application specific controllers are available for HVAC
equipment typically used in the target market. These include
constant volume air handling units (CVAHU), variable air
volume terminal units (VAV II), fan coil units (FCU), unit
ventilators (UV), Hydronic units (HYD), Remote Input/Output
unit (RIO), Chilled Ceiling Controller (CHC), thermostats and
valve applications (fin tube radiation, convector, manual fan
FCU, unit heater). T7350 and T7300F/Q7300H thermostats
are available for applications requiring programmable
thermostats. Refer to the respective Excel 10 controller,
T7350 and/or T7300F/Q7300H Application Guide for specific
information regarding input/output requirements, controller
operation, and configuration. See Table 1 on page 5 to identify
literature for a specific controller.
24
Command Display (CD and CD2) allows viewing and
modifying the parameters of other units over the LonWorks®
network.
Refer to the respective Excel 15 controller Application Guide
for specific information regarding input/output requirements,
controller operation, and configuration. See Table 1 on page 5
to identify literature for a specific controller.
Other units are:
• CXS/CXL Honeywell Variable Frequency Drive (VFD)
The Excel VRL CX/CXL/CXS frequency drive is used for
controlling speed and torque of three-phase AC motors.
Excel VRL CX/CXL/CXS frequency converters can be
connected to LonWorks® network by using CX203OPT
option board. They can then be controlled, monitored, and
programmed from the LonWorks® network.
• Vacon NX Variable Frequency Drive (NXS/NXP/NXL VFD)
Vacon NX frequency converter (NXVFD) is used to control
speed and torque of three-phase AC motors. Refer to
www.Vacon.com for more information on NX VFD. The NX
VFD can be connected to LonWorks® network using
NXOPTC4 option board. They can then be controlled,
monitored, and programmed from the LONWORKS®
network through LONSPEC™.
Determine the input and output device requirements for each
controller used in the system. Select input and output devices
compatible with the controller and the application. Consider
the operating range, wiring requirements, and the
environment conditions when selecting input/output devices.
When selecting actuators for modulating applications consider
using floating control. In direct digital control applications
floating actuators will generally provide control action equal to
or better than an analog input actuator for lower cost.
Determine the location of controllers, sensor, actuators and
other input/output devices and create wiring diagrams. See
“Step 3. Prepare Wiring Diagrams” on page 29.
Light Commercial Building Solution
LIGHT COMMERCIAL BUILDING SOLUTION
The application engineer must review the Direct Digital
Control (DDC) job requirements. This includes the Sequences
of Operation for the W7760A,C Controllers, and for the
system as a whole. Usually there are variables that must be
passed between the W7760A,C Controllers and other Excel
10 controller(s) that are required for optimum system wide
operation. Typical examples are the TOD, Occ/Unocc signal,
the outdoor air temperature, the demand limit control signal,
and the smoke control mode signal.
It is important to understand these interrelationships early in
the job engineering process to ensure implementation when
configuring the controllers. Refer to the controller Application
Guides (see Table 1 on page 5), the LONSPEC™ ZL7760A
software Help for configuring information for LCBS devices,
and “LonSpec Data Sharing” on page 38.
The LONWORKS® Bus FTT-10A communication wiring
between controllers is a free topology scheme that supports
daisy chain, T-tap, star, and/or loop, wiring configurations.
Refer to the LONWORKS® Bus Wiring Guidelines form,
74-2865 for complete description of network topology rules.
See Application Step 2. Lay Out Communications and Power
Wiring for more information on bus wiring layout, and see
Application Step 4. Prepare Wiring Diagrams, for wiring
details.
The Light Commercial Building Solution implementation of
LonWorks® supports 1 subnet per network while routers are
not supported. Since there is only 1 sub-network per network
in the LCBS, all capabilities and limitations of a sub-network
apply to the network. The term network is often used in lieu of
sub-network in LCBS discussions.
A sub-network supports a maximum of 127 nodes. Each
LONWORKS® Bus device constitutes one node.
A maximum of 120 LCBS devices can be configured on a
single LONWORKS® Bus sub-network. LONSPEC™ and
RapidZone reserves seven nodes for LONTALK® adapters for
connecting software tools. The remaining 120 nodes are used
for LCBS devices.
If the number of LCBS devices on the sub-network exceeds
60, a Q7740 repeater is required.
In an XL15A solution further limitations on the number of
devices on a bus may result from alarm handling
requirements.
• The maximum number of W7760A Building Managers on a
sub-network is 4.
• The maximum number of W7761A RIO devices is 3 per
W7760A and C.
• The maximum number of external nodes that can be
mapped to a W7760A will support is 20.
• The maximum number of nodes with alarm reporting is 84
(4 W7760A plus 4 X 20 external = 84). Additional devices
may used up to the maximum of 120. However, only 84
devices will report alarms.
• Each W7760C control loop function
• Each W7760A can support alarm handling for a maximum
of 20 network objects in addition to itself and the
associated W7761A’s. Each control device on the network
is 1 object effectively limiting the sub-network to 96 control
devices In addition each W7760C Plant Manager control
loop and logic loop is a network object.
25
• Each W7760A and C, Excel 15 controllers will support a
maximum of 3 W7761A Remote Input/Output (RIO)
devices. A W7761 must be associated with a W7760A or C
and cannot be associated to more than 1 W7760A or C.
Therefore, the maximum number of W7761A’s in a network
is limited to 3 times the number of W7760A and C’s.
Refer to LonWorks® for LCBS (form number 74-2865_2) for
complete description of network topology rules and the
maximum wire length limitations. If a longer LONWORKS® Bus
sub-network is required, a Q7740 Repeater can be added to
extend its length. Each sub-network can have a maximum of
one repeater.
All LONWORKS® Bus segments require a termination device.
Doubly terminated daisy-chain requires 2 termination devices.
For more details on LONWORKS® Bus termination, refer to
LonWorks® for LCBS - Cable Termination (form number 742865_2) or see Application Step 3. Lay Out Communications
and Power Wiring, and the LONWORKS® Bus Termination
Module subsection in Application Step 4.
Step 2. LayOut Communications and Power
Wiring
Communications
The LONWORKS® Bus communications bus is a 78 kbps serial
link that uses transformer isolation and differential Manchester
encoding.
Installation of communications wiring requires special
considerations that may vary from project to project. It is
important that exact installation instructions be provided to the
installer.
Guidelines for communications wiring are as follows:
— All field wiring must conform to local codes and ordinances.
— Approved cable types for LONWORKS® Bus communications
wiring is Level IV 22 AWG (0.34 mm2) plenum or nonplenum rated unshielded, twisted pair conductors. For nonplenum areas, Honeywell U.S. part AK3781 (one pair) or
U.S. part AK3782 (two pair) can be used. In plenum areas,
U.S. part AK3791 (one pair) or U.S. part AK3792 (two pair)
can be used. Additionally, Echelon® approved cable can be
used. Contact Echelon® Corp. Technical Support for the
recommended vendors of Echelon® approved cables (refer
to LonWorks® for LCBS - Network Cabling and
Connections - Table 8 through 12, form 74-2865).
— Unswitched 24 Vac power wiring can be run in the same
conduit as the LONWORKS® Bus cable.
— Do not bundle output wires with sensors, digital inputs, or
communications LONWORKS® Bus wires.
— Do not use different wire types or gauges on the same
LONWORKS® Bus segment. Using different wire types or
gauges can result in line impedance changes that can
cause unpredictable reflections on the LONWORKS® Bus.
— In noisy (high EMI) environments, avoid wires running
parallel to noisy power cables, motor control centers, or
lines containing lighting dimmer switches, and keep at least
3 in. (76 mm) of separation between noisy lines and the
LONWORKS® Bus cable.
— Each LONWORKS® Bus segment containing up to 120 (see
Table 18) Excel 15/10 Controllers, T7350s, T7300F/
Q7300Hs, Command Displays, requires the installation of
a 209541B Termination Module for a single terminated
74-3679—1
LIGHT COMMERCIAL BUILDING SOLUTION
LONWORKS® Bus or two 209541B Termination Modules for
a doubly terminated LONWORKS® Bus. For more details on
LONWORKS® Bus termination, refer to LonWorks® for
LCBS - Cable Termination (form number 74-2865_2).
— Make sure that neither of the LONWORKS® Bus wires is
grounded.
— LONWORKS® Bus cable extended to T7770 Wall Modules
to connect the LONWORKS® jack must be included in the
total wire length.

Power
A power budget must be calculated for each device to
determine the required transformer size for proper operation.
A power budget is simply the summing of the maximum power
draw ratings (in VA) of all the devices to be controlled. This
includes the controller itself and any devices powered from
the controller such as equipment actuators (ML6161, or other
motors) and various contactors and transducers.
44
IMPORTANT
• If a controller is used on Heating and Cooling
Equipment (UL 1995, U.S. only) and transformer
primary power is more than 150 volts, connect the
transformer secondary common to earth ground.
• When multiple controllers operate from a single
transformer, you must connect the same side of the
transformer secondary to the same power input
terminal in each device. The earth ground terminal
(W7760C Terminal 49) must be connected to a
verified earth ground for each controller in the group.

— If a longer LONWORKS® Bus segment is required, a Q7740
Repeater can be added to extend its length. Each subnetwork can have a maximum of one repeater. If a Q7740
repeater is used, each sub-net segment must be
terminated as described (refer to LonWorks® for LCBS Cable Termination (form number 74-2865_2).
NOTE: Special consideration must be given to connecting
the LONWORK®S Bus to the W7760A Building
Manager and W7760C Plant Manager. Each is built
with 2 pairs of terminals for connecting the bus. The
jumper between the terminal pairs is on the controller
printed circuit board. Removing the controller from
the sub-base will interrupt the bus circuit. To maintain
sub-net circuit continuity install jumpers between
terminals or install the “in” and “out” bus cable on the
same terminals. See W7760 LonWorks® Wiring
Option Fig. 6 through 8.

POWER BUDGET CALCULATION EXAMPLE
The following is an example power budget calculation for a
typical W7760C Excel 15 Plant Controller. While the example
is shown for a W7760C the process is applicable for all LCBS
controllers.
Assume a W7760C unit with a fan, two stages of D/X cooling,
modulating steam valve for heating, and modulating
economizer dampers. The power requirements are:

The W7760C System example requires 41.9 VA of peak
power; therefore, a 75 VA AT88A Transformer could be used
to power one controller of this type, or a 100 VA AT92A
Transformer could be used to power two of these Plant
Controllers and meet NEC Class 2 restrictions (no greater
than 100 VA). See Fig. 44 and 45 for illustrations of power
wiring details. See Table 5 for VA ratings of various devices.

For contactors and similar devices, the in-rush power ratings
should be used as the worst case values when performing
power budget calculations. Also, the application engineer
must consider the possible combinations of simultaneously
energized outputs and calculate the VA ratings accordingly.
The worst case, that uses the largest possible VA load, should
be determined when sizing the transformer.
Each W7760C requires 24 Vac power from an energy-limited
Class II Power Source. To conform to Class II restrictions (U.S.
only), transformers must not be larger than 100 VA. A single
transformer can power more than one W7760C Controller. Fig.
9 shows a generic power wiring diagram for multiple devices
using one transformer.
IMPORTANT
Use the heaviest gauge wire available, up to 14
AWG (2.0 mm2) with a minimum of 18 AWG (1.0
mm2), for all power and earth ground wiring.
Screw type terminal blocks are designed to accept
only one 14 AWG (2.0 mm2) conductor. Two or more
wires that are 14 AWG (2.0 mm2) can be connected
with a wire nut. Include a pigtail with this wire group
and attach the pigtail to the terminal block.
GUIDELINES FOR POWER WIRING ARE AS FOLLOWS:
— For multiple controllers operating from a single transformer,
the same side of the transformer secondary must be
connected to the same power input terminal in each
device. The earth ground terminal must be connected to a
verified earth ground for each controller in the group. See
Fig. 9. Controller configurations are not necessarily limited
to two devices, but the total power draw including
accessories cannot exceed 100 VA when powered by the
same transformer (U.S. only).
— Many LCBS controllers require all loads to be powered by
the same transformer that powers the controller.
— Keep the earth ground connection wire run as short as
possible. Refer to Fig. 9.
— Do not connect earth ground to controller digital or analog
ground terminals. Refer to Fig. 9.
— Unswitched 24 Vac power wiring can be run in the same
conduit as the LONWORKS® Bus cable.
— Maintain at least a 3 in. (76 mm) separation between Triac
outputs and LONWORKS® Bus wiring throughout the
installation.

In this situation, the engineer basically has three alternatives:
1. Use a larger transformer; for example, if an 80 VA
model is used an output of 24.4 volts minus the four volt
line loss supplies 20.4V to the controller. See Fig. 10.
Although acceptable, the four-volt line-loss in this
example is higher than recommended. See the
following IMPORTANT note.
2. Use heavier gauge wire for the power run. 14 AWG
(2.0 mm2) wire has a resistance of 2.57 ohms per 1000 ft.
which, using the preceding formula, gives a line-loss of
only 1.58 volts (compared with 4.02 volts). This would
allow a 40 VA transformer to be used. 14 AWG (2.0 mm2)
wire is the recommended wire size for 24 Vac wiring.
3. Locate the transformer closer to the controller, thereby
reducing the length of the wire run, and the line loss.

USED FOR 24V COMMON. THE POWER WIRE FOR 24 VAC MUST BE THE
SAME ON ALL DEVICES.
4
EACH CONTROLLER EARTH GROUND TERMINAL MUST BE CONNECTED TO
EARTH GROUND. KEEP THE EARTH GROUND WIRE LENGTH TO A MINIMUM.
USE THE HEAVIEST GAUGE WIRE AVAILABLE, UP TO 14 AWG (2.2 SQ. mm)
WITH A MINIMUM OF 18 AWG (1.0 SQ mm) FOR THE EARTH GROUND.
5
FOR CONTROLLERS USED IN HEATING/COOLING EQUIPMENT SUBJECT TO
UL1995 AND PRIMARY POWER GREATER THAN 150V, ONE SIDE OF THE
TRANSFORMER SECONDARY MUST BE GROUNDED.
M22721
Fig. 9. Power wiring details for multiple LCBS Devices.
Line Loss
LCBS Controllers must receive a minimum supply voltage of
20 Vac. If long power or output wire runs are required, a
voltage drop due to Ohms Law (I x R) line loss must be
considered. This line loss can result in a significant increase in
total power required and thereby affect transformer sizing.
The following example is an I x R line-loss calculation for a
200 ft. (61m) run from the transformer to a W7760C Controller
drawing 37 VA using two 18 AWG (1.0 mm2) wires.
The formula is:
Loss = [length of round-trip wire run (ft.)] x [resistance in
wire (ohms per ft.)] x [current in wire (amperes)]
From specification data:
18 AWG twisted pair wire has 6.52 ohms per 1000 feet.
Loss = [(400 ft.) x (6.52/1000 ohms per ft.)] x
[(37 VA)/(24V)] = 4.02 volts
This means that four volts are going to be lost between the
transformer and the controller; therefore, to assure the
controller receives at least 20 volts, the transformer must
output more than 24 volts. Because all transformer output
voltage levels depend on the size of the connected load, a
larger transformer outputs a higher voltage than a smaller one
for a given load. Fig. 10 shows this voltage load dependence.
The issue of line-loss is also important in the case of the
output wiring connected to the Triac digital outputs. The same
formula and method are used. The rule to remember is to
keep all power and output wire runs as short as practical.
When necessary, use heavier gauge wire, a bigger
transformer, or install the transformer closer to the controller.
IMPORTANT
No installation should be designed where the line
loss is greater than two volts to allow for nominal
operation if the primary voltage drops to 102 Vac
(120 Vac minus 15 percent).
To meet the National Electrical Manufacturers Association
(NEMA) standards, a transformer must stay within the NEMA
limits. The chart in Fig. 10 shows the required limits at various
loads.
With 100 percent load, the transformer secondary must
supply between 23 and 25 volts to meet the NEMA standard.
When a purchased transformer meets the NEMA standard
DC20-1986, the transformer voltage regulating ability can be
considered reliable. Compliance with the NEMA standard is
voluntary.

transformer is just under 100 percent loaded (for the 37 VA
controller) and, therefore, has a secondary voltage of
22.9 volts. (Use the lower edge of the shaded zone in Fig. 10
that represents the worst case conditions.) When the I x R
loss of four volts is subtracted, only 18.9 volts reaches the
controller, which is not enough voltage for proper operation.

ATTACHING 2 OR MORE WIRES TO THE SAME TERMINAL
For field wiring, when attaching two or more wires, other than
14 AWG (2.0 mm2), to the same terminal, twist wires together.
See Fig. 22. Deviation from this rule can result in improper
electrical contact.
Wire to the terminal blocks as follows:
1. Strip 1/2 in. (13 mm) insulation from the conductor.
2. If using a single wire in the required terminal location,
cut the wire to 3/16 in. (5 mm) insert and tighten the
screw to complete the termination.
3. If two or more wires are being inserted into one terminal
location, twist the wires together a minimum of three
turns before inserting them.
4. Cut the twisted end of the wires to 3/16 in. (5 mm)
before inserting them into the terminal and tightening
the screw.

Step 5. Configure Controllers
Step 6. System Startup
Controllers are configured using ZL7760A LONSPEC™,
ZL7751A RapidZone, or ZL7300A LonStat™ configuration
software tools. Refer to the individual LCBS controller
Application Guide for complete information on configuring the
controller. For a list of controllers and literature see
“Applicable Literature” on page 5.
System startup assumes that the controller has been
configured in a software tool and that some, if not all network
devices have been installed. It is preferred that all devices be
operational, but recognized that projects may be brought on
line over time.
The following identifies the tools used for each of the 5
solution architectures:
• XL15A Solution - ZL7760A LONSPEC™.
• XL15B Solution - ZL7760A LONSPEC™ (The W7760B
Building Manager has an internal setup function).
• RapidZone Solution - XL7751A RapidZone software.
• LonStat™ - ZL7300A LonStat software. (LONSPEC™ can
be used but LonStat™ is simpler for the user.)
• Unconfigured CVAHU - None, the controllers use factory
default parameters. Any software download will delete the
factory default parameters.
Projects configured with RapidZone can be saved as a
LONSPEC™ backup database and restored to LONSPEC™ to
include the RapidZone Solution in an XL15A or XL15B
Solution. While it is possible to manually configure a
RapidZone application using LONSPEC™, the task is
extremely complex and tedious.
LonStat™ does not create a database. It must be connected
to one or more T7300F/Q7300H communicating commercial
programmable thermostats to be used.
A LONSPEC™ database backup including one created in
RapidZone can be associated to ZL7762A LONSTATION™
monitoring software to significantly reduce the time required to
commission LONSTATION™.
LONSTATION™ can be used to monitor the XL15A Solution, the
RapidZone Solution, and the LonStat™ Solution. It cannot be
used to monitor the XL15B Solution or Unconfigured CVAHU
Solution.

The major concern for projects being started over time is that
the data sharing may not be complete to meet application
needs. There is also a risk of electrical damage to one or
more network devices if a device is connected to the network
while the network is operational.
Check Installation and Wiring:
Inspect all wiring connections at the controller terminals, and
verify compliance with job drawings. If any wiring changes are
required, first be sure to remove power from the device before
starting work. Pay particular attention to:
— 24 Vac power connections. Verify that multiple devices
powered by the same transformer are wired with the
transformer secondary connected to the same input
terminal identification on each controller. See Fig. 9.
Controller configurations are not necessarily limited to two
devices, but the total power draw including accessories
cannot exceed 100 VA when powered by the same
transformer (U.S. only).
— Device wiring. Be sure that each device is wired to a
verified earth ground using a wire run as short as possible
with the heaviest gauge wire available, up to 14 AWG (2.0
mm2) with a minimum of 18 AWG (1.0 mm2) for each
controller in the group. See Fig. 9.
— Verify Triac wiring to external devices uses the proper load
power/24 Vac hot terminals. Check for 24 Vac with a meter.
NOTE: All wiring must comply with applicable electrical
codes and ordinances or as specified on installation
wiring diagrams.
LIGHT COMMERCIAL BUILDING SOLUTION
VERIFY TERMINATION MODULE PLACEMENT
The installation wiring diagrams should indicate the locations
for placement of 209541B Termination Module(s). Refer to
LONWORKS® Bus Wiring Guidelines (form number 74-2865_2)
and the Excel 10 FTT Termination Module Installation
Instructions form, 95-7554. Correct placement of the
termination module(s) is required for proper LONWORKS® Bus
operation.
Power Up
Apply power to the controller(s). Observe for any physical
signs of malfunctions.
Observe the LED on the controller. The LED provides a visual
indication of the status of the device. When the controller
receives power, the LED should appear in one of the following
allowable states:
1. Off - no power to the processor.
2. Continuous On - processor is in initialized state.
3. Slow Blink - controlling, normal state.
4. Fast Blink - when the controller has an alarm condition.
See below for additional information on alarms.
Assigning Neuron® ID
Each LCBS device communicating on the network has a
neuron number assigned to the transceiver by the chip
manufacturer. This number is printed on a 3 part identification
label attached to each device. One part of the label is
permanently affixed to the device and the other 2 parts are
removable gummed labels that can be affixed to job
documentation.
Assigning a Neuron® ID allows a device on the LONWORKS®
Bus to be positively identified. The controller Neuron® ID
number can be used to confirm the physical location of a
particular Excel 15, Excel 10, T7350, T7300F/Q7300H, VFD,
and NX VFD.
There are two methods of assigning a Neuron ID for an LCBS
controller. One uses a hardware service pin button on the
controller and manually entering the Neuron ID is the second.
When an Assign ID command (use the service pin button is
issued from LONSPEC™, RapidZone, or LonStat™, the
configuration tool goes into the SERVICE_MESSAGE mode
for five minutes. In the SERVICE_MESSAGE mode, pressing
37
the hardware service pin button on a controller causes the
Service Message to be broadcast on the network. All other
functions are normal in the SERVICE_MESSAGE mode. Use
of the Service Pin assures that the correct device is being
selected for configuration download from the tool.
When manually entering the Neuron® ID and issuing the
Assign ID command, LONSPEC™, RapidZone, or LonStat™
locates and communicates directly with the controller (the
controller does not go into the SERVICE_MESSAGE mode in
this case). Refer to the LONSPEC™ ZL7760A software Help for
more information on the ID assignment process.
Alarms
In addition to the following information, refer to the Installation
Instructions and Checkout and Test manual for each product.
See the “Applicable Literature” on page 5 for form numbers.
When an LCBS controller has an alarm condition, it reports it
to the central node on the LONWORKS® Bus (typically, a
W7760A or W7760B Building Manager). Information
contained in an alarm message is:
• Subnet Number:
LONWORKS® Bus segment that contains the node that has
the alarm condition.
• Node Number:
Node that has the alarm condition.
• Alarm Type:
Specific alarm being issued.
Download the Configuration
Once the tool has the neuron® ID it can download the
controller configuration to the controller. The download may
take several minutes for each controller. The files being
downloaded are shown in the download screen of the tool.
Checkout
Once the configuration has been downloaded to the controller,
the controller operation can be checked. Refer to the
controller documentation to determine what procedures
should be followed for checkout. The configuration tool can be
used to monitor the controller to check the operation. Some
controllers permit the configuration tool to manually override
the outputs, others do not.

LONSPEC DATA SHARING
Light Commercial Building Solution
Introduction to Data Sharing
Data sharing for the Light Commercial Building Solution (LCBS)
is configured using one of the LCBS configuration tools;
LONSPEC™ ZL7760A, RapidZone, or LonStat. The LCBS
configuration tools configure the data sharing as part of the
configuration process and automatically selects the
communication mechanisms as appropriate. A brief overview
of the mechanisms used is helpful in planning a system
configuration.
The LONWORKS® communications protocol uses a number of
mechanisms to transfer data from one network device to
another. This discussion is limited to 2 mechanisms used to
share data between 2 or more devices on a LONWORKS®
network in the Light Commercial Building Solution and is a brief
and simplified summary of the function of these 2
communications mechanisms. For complete and detailed
information on LonWorks® operation, refer to published
documentation available from Echelon® Corp.
Data sharing or the exchange of data between 2 or more
devices on a LONWORKS® network in the light commercial
building solution uses one of two communication
mechanisms, polling or binding.
Polling is a process in which one device on the network
request data from another device on the network. The
originating device sends a message requesting the data from
a specific device and that device responds with the specific
data requested. If the originating device needs data from
multiple controllers it must send an individual request to each
controller from which it needs data. In this case the polling
device is configured to request data from a single or multiple
network devices. The most common use of polling is,
supervisory devices such as LONSTATION™, W7760A or B
Building Manager, W7760C Plant Controller, S7760A
Command Display Module, and LONSPEC™ monitoring
system. Another example is configuring a controller to use a
“remote” point as an input. In LONSPEC™, RapidZone, and
LonStat all polling is configured automatically as the network
devices are configured.
Binding is the process where one device is configured to read
data being transmitted by another device. The device
originating the data is not sending the data to any specific
device on the network, but any and all devices configured to
read the data will do so. In this case the device receiving the
data is configured to read the data from an originating
controller. An example of binding is configuring an outdoor air
temperature sensor on one controller and referring all other
devices on the network to it.
The data shared between various network devices is
transmitted and received as network variables (NV). Within a
device the network variable is identified as being an output
(nvo) or input (nvi). A nvo transmits specific data from the
device. A nvi receives specific data from the network for use
by the device. In data sharing the source is a nvo and the
destination is a nvi.
The LONMARK® Association defines Standard Network
Variable Types (SNVT) for each registered profile.
Manufacturers define additional network variables that are
74-3679—1
specific to a given device. SNVTs are used to provide open
communication between multiple manufacturers’ devices. A
manufacturer’s proprietary network variables are used to
implement functionality beyond the profiles and to enhance
device or system operation. LONSPEC™, RapidZone, and
LonStat make no distinction between SNVTs and proprietary
network variables. LonMark® SNVTs for each controller are
shown in the Specification Data sheets for each controller.
See Table 1 Applicable Literature for specific literature
numbers.
In RapidZone and LonStat the applications are defined in the
software tool and binding is done automatically and no user
activity is required. While LONSPEC™ also does much of the
binding automatically, it is a more flexible tool supporting
custom applications that may require the user to configure the
binding in a configuration screen called “Refer Points”.
Each controller point available as a data source or destination
is given a point name. The point name used in LONSPEC™
“Refer Points” is not the user defined point name. The point
names are consistent for all controllers of the same model but
unique for each controller model. The point names are as
shown in Tables 9 through 28.
The LONSPEC™ configuration screen “Refer Points” sorts the
available destination points based on the source point type.
The sorting is based on the LonWorks® Standard Network
Variable Type (SNVT) which may include many controller
variables that are very different in function and not appropriate
to share. In LONSPEC™ each specific variable is identified by a
unique name. For example the LonWorks® variable
“SNVT_Temp_p” is used for outdoor air temperature, space
temperature, discharge air temperature, effective setpoint,
setpoint, and setpoint offset. In LONSPEC™ each of these
variable is given a unique name. However, in “Refer Points”
when any one of the these variables is selected as the source
point all of the variables of this type will be shown in the
destination points list. It would be inappropriate to bind the
outside air temperature to the setpoint. The user must ensure
the binding meets the application requirements. Tables 9
through 28 show the relationship of the source and destination
points.
In LCBS all network variables (points) exist for each controller
even if not configured. Configuring the input tells the controller
to expect data on the input and in Excel 10 controllers may
enable specific control functions. It is possible to configure
data sharing using points that are not configured. If an
unconfigured point is used as a source point (nvo), no data
will be sent and all receiving controllers will report it as an
alarm. If the unconfigured point is a destination point, the data
will be ignored by the controller. LONSPEC™ does not check to
determine if the points used have been configured.
Data Sharing for Control Devices
Data sharing occurs in the configuration of the control devices
(controllers) listed below. Supervisory devices such as
Command Display, LONSTATION™, and LONSPEC™ are not
included in this discussion.
NOTE: Notation Convention: >> indicates a menu or field

provides tables listing all available source and destination
points by controller type. The tables identify the appropriate
pairings.
Time of Day Scheduling
Time keeping and Time of Day (TOD) scheduling is done in
the W7760A Building Manager and T7350H or T7300F/
Q7300H Commercial Thermostat with communicating subbase.
The W7760A has 7 schedules that can be assigned to the 6
Control Loops, 8 Start/Stop Loops, and 20 network objectsa
using the LONSPEC™ Schedule Assign functionb. The
T7350H has a single schedule that can be assigned to an
unlimited number of objects. The T7300F/Q7300H has a
single schedule that can be assigned to 4 network objects.
Each of the network objects assigned to a W7760A, T7350H,
or T7300 schedule uses a network variable output (nvo) to
send the Current State, Next, and Time Until Next Change of
State (TUNCOS) across the LonWorks® bus to a
corresponding network variable input (nvi). There are 20 nvo’s
available from a W7760A, one from a T7350H, and 4 from a
T7300. LONSPEC™ binds the nvi to the respective nvo with no
additional intervention by the user.
Using the LONSPEC™ Schedule Assign function is the
optimum method for scheduling XL10 controllers and
W7760C Control Loops and Start/Stop Loops. However if the
74-3679—1

LIGHT COMMERCIAL BUILDING SOLUTION
number of Schedule Assign(ments) are insufficient for an
application, it is possible to bind additional objects to a
W7760A, T7350H, or T7300F/ Q7300H using the LONSPEC™
>>Network>>Refer Points function.
source controller to multiple controller requiring the data. It is
necessary to use the LONSPEC™ >> Network >> Refer Points
to bind the source point (network variable output – nvo) to the
destination points (network variable input – nvi).
NOTE: This method extends the number of objects that can
be scheduled from a controller but it does not expand
the number of schedules available.
To perform the Refer Points function, it is necessary that the
controllers be available in the LONSPEC™ project. Good
engineering practice would dictate that the controllers be
configured prior to referring points
PROCESS:
5. Determine the number of schedules required for the
objects to be scheduled. The total cannot exceed the
number of schedules available from the source controller (8 for W7760A and one for T7350H and T7300A).
6. The source controller (W7760A and T7300F/Q7300H)
and the destination controllers (objects) must be
available in the LONSPEC™ project. Best practices
dictates that the controllers be configured, especially
the source controller schedules.
7. Use LONSPEC™ Schedule Assign to assign each
schedule to be used to at least 1 object. It is necessary
to review the T7350, T7300F/Q7300H, or W7760A
Building Manager configuration for schedule assignment and manually record the schedule information for
the object assigned and the number sequentially of the
assignment (1 through 4 for T7300F/Q7300H and 1
through 20 for W7760A).
8. In the LONSPEC™ Refer Points screen, select the
desired schedule (T7350 Time of Day Out (TOD) [1],
T7300F/Q7300H TOD Out [1-4], or W7760A TOD Event
[1-20]) as the source point and refer it to the time of day
input for the control device.
The controller to which the outdoor air sensor is physically
connected is the source controller and the input must be
configured for the function. Configuring an Excel10 input
automatically sets the appropriate network variable output for
the controller. When configuring an W7760A Building
Manager or W7760C Plant Manager, it is necessary to set the
network variable type when configuring the analog input.
It is possible to have multiple source controllers for the same
outside measurement (network variable). This can be
desirable with a building or campus situated such that
significant differences can exist for various measurements.
For such configurations, the user must ensure the correct
source controller is selected for the destination controller.
CAUTION
When using Refer Points, LONSPEC™ does not
check to verify that the source has been
configured.
The user must ensure the correct source and
destination controllers and points are selected in the
configuration process.
Outdoor Air Conditions
The following table provides by controller and outdoor air
measurement the names of the network variables used in
Refer Points.

Sharing the Bypass operation from one control device to
The Excel10 W7750A,B,C CVAHU, W7751B,D,F,H,J VAV II,
and W7753 Unit Ventilator controllers may all be configured
with network commandable digital output points called Free
points. Generally these points are configured as remote points
when configuring Excel 15 start-stop, control loops, or logic
loops. However, they can also be controlled by binding them
to an appropriate output from another Excel10 controller. For
example, a switch might be wired to a digital input on a W7750
CVAHU controller configured as Monitor (source). This could
then be referred to the Free 1 output on another controller
(destination) wired to control lights. When the switch is
activated on the source controller, the output on the
destination controller would be activated turning on the lights.
Any input of network output of NV type 95 can be used as the
source for activating a Free point in Excel 10. It is the user’s
responsibility to ensure the source is appropriate for the
application.
another is done in the Refer Points screen. It is important to
note that it is the bypass operation of the control device and
not the wall module push button being shared. A number of
factors determine the actual bypass status for a control
device. Refer to the Application Guide for the specific
controller for detailed information on the sequence of
operation.
When the network bypass input is active, the bypass timer of
the destination is not used and the destination controller will
execute the bypass function as long as the source object is in
bypass. When the source bypass goes inactive the
destination bypass function will continue for 300 seconds.
This permits multiple source objects to be referred (bound) to
the same destination object and be read so that any one of
the source objects being in bypass will cause the destination
object to be in bypass.
To refer bypass in the Refer Points screen, select the source
control device bypass output and the destination object
bypass input and add to the Bound Points list. See the Refer
Points tables in Appendix A for a complete list of source and
destination points by controller type.
