Introduction
This document contains the necessary information you need to incorporate a MicroTech III Unit Controller (i.e. Applied
Rooftop, Self-Contained, Maverick II™ or Rebel™) from Daikin Applied into a building automation system (BAS). It lists
all BACnet® properties, LONWORKS variables, and corresponding MicroTech III Unit Controller data points. It also contains
the BACnet Protocol Implementation Conformance Statement (PICS). BACnet and LONWORKS terms are not defined.
Refer to the respective specifications for definitions and details.
Unit Controller Data Points
The MicroTech III Unit Controller contains data points or unit variables that are accessible from three user interfaces: the
unit keypad, a BACnet network (BACnet/IP or MS/TP), or a LONWORKS network. Not all points are accessible from each
interface. This manual lists all important data points and the corresponding path for each applicable interface. Refer to OM
920 (available on www.DaikinApplied.com) for keypad details. This document contains the network details necessary to
incorporate the MicroTech III Unit Controller into the network.
Protocol Definitions
The MicroTech III Unit Controller can be configured in either an interoperable BACnet or LONWORKS network. The
controller must have the corresponding communication module installed for network integration (see Reference Document
section for corresponding part numbers). There are three communication modules: BACnet/IP, BACnet MS/TP
(Master/Slave Token Passing), and LONWORKS. There are two LONWORKS modules: one in accordance with the LonMark
Space Comfort Controller (General) functional profile and one in accordance with the Discharge Air Controller functional
profile.
BACnet Protocol
BACnet is a standard communication protocol for Building Automation and Control Networks developed by the American
National Standards Institute (ANSI) and American Society of Heating, Refrigeration and Air-conditioning Engineers
(ASHRAE) specified in ANSI/ASHRAE standard 135-2008. It addresses all aspects of the various systems that are applied
to building control systems. BACnet provides the communication infrastructure needed to integrate products manufactured
by different vendors and to integrate building services that are now independent.
LONWORKS Networks
A control network specification for information exchange built upon the use of LonTalk for transmitting data developed by
the Echelon Corporation.
LonTalk Protocol
A protocol developed and owned by the Echelon Corporation. It describes how information should be transmitted between
devices on a control network.
LonMark Certification
LonMark certification is an official acknowledgement by the LonMark Interoperability Association that a product
communicates using the LonTalk protocol and transmits and receives data per a standard LonMark functional profile. The
LONWORKS communication modules are LonMark 3.4 certified in accordance with the Space Comfort Controller (SCC) and
Discharge Air Controller (DAC) functional profiles.

Basic Protocol Information
Setting Unit Controller Communications Parameters
There are 12 communication parameters involved in setting up the unit controller for proper communication with the four
communication module options (BACnet IP, BACnet MS/TP, LONWORKS SCC or LONWORKS DAC). These parameters
are set differently depending on which communication module is ordered and shipped with the unit. The table below lists
the three possible sets of default parameter settings. Not all the parameters apply to all the module options. The bold
parameters can be changed using the keypad display located on the unit controller.

BACnet Networks
Compatibility
The MicroTech III Unit Controller Unit Controller is tested according to the BACnet Testing Laboratory (BTL) Test Plan.
It is designed to meet the requirements of the BACnet Standard (ANSI/ASHRAE 135-2008) as stated in the Protocol
Implementation and Conformance Statement (PICS). However, it is not BTL listed. The PICS is located at the end of this
manual or the separate PICS document, ED 15113 (available on www.DaikinApplied.com.)
BACnet Objects
MicroTech III Unit Controllers incorporate standard BACnet object types (i.e., object types defined in the BACnet
Standard) that conform to the BACnet Standard. Each object has properties that control unit variables or data points. Some
object types occur more than once in the MicroTech III Unit Controller; each occurrence or instance has different properties
and controls different unit variables or data points. Each instance is designated with a unique instance index. Some
8
ED15112-14
properties can be adjusted (read/write properties, e.g., setpoints) from the network and others can only be interrogated (readonly properties, e.g., status information).
Each data point accessible from a BACnet network is described with a table that gives the Object Identifier, Property
Identifier, Full BACnet Reference or path, and the Name enumeration of the property.

Object Identifier
Object Identifiers are each designated with an Object type as defined in the BACnet specification. The first column of the
data point definition gives the object type. This object happens to be Return/Exhaust Fan Status (See page 104.)
The object identifier is a property of the object that you can read from the object. The name of the property is
“Object_Identifier” and the property identifier is 75.
Each object in the unit controller has a unique identifier. BACnet object identifiers are two-part numbers of BACnet Object
Identifier data type. The first part identifies the object type (the first 10 bits of the 32-bit BACnet Object Identifier [See
ANSI/ASHRAE 135-2008 BACnet A Data Communication Protocol for Building Automation and Control Networks]). The
first column of the data point definition gives the object type. The second part identifies the instances of that particular
object type (the last 22 bits of the 32-bit BACnet Object Identifier).
The object identifier is shown in the data points listing as two numbers. The first number is shown in the Type ID column
and designates the Object type enumeration. The second number is shown in the Instance column and designates the
instance of that particular object type.
The object identifier is a property of the object that you can read from the object code. The name of the property is
“Object_Identifier” and the property identifier is 75. The ASHRAE BACnet specification reserves the first 128 numbers for
ASHRAE defined objects. Manufacturers may define additional object types and assign a number above 127 as long as they
conform to the requirements of the ASHRAE BACnet specification.
Each object also has a name. Object names are character strings. The object name is a property of the object that you can
read from the object. The name of the property is “Object_Name” and the property identifier is 77.
Objects are sometimes referred to as an object type and instance number as they are in the BACnet specification. The
example object above would be: Binary Output, Instance 1.
Property Identifier
Each object has a number of properties or attributes. Each property has a unique identifier of BACnet Property Identifier
data type. Property identifiers are an enumerated set; a number identifies each member. The Property Identifier enumeration
number is shown in the Property ID column. In the example above the property identifier is 85.
Property Name
Each property also has a unique name. Property names are character strings and shown in the Property Name column. In the
example above the property name is Present Value.
Full Reference
The full reference is the path of the property within the network where the MicroTech III Unit Controller resides. It is a
character string equivalent to the object identifier and the property identifier. In the example above the full reference is
<Device Name>.ExhFanState.Present_Value.
Enumerated Values
Some properties are standard data types and some are enumerated sets. If the property value is an enumerated set, all
enumerated values and corresponding meaning are given in the Enumeration column of the data point listing.
ED15112-14

MicroTech III Unit Controller Device Object
Each BACnet compatible device must have one and only one BACnet Device Object.
Device Object Identifier
The MicroTech III Unit Controller Device Object Identifier uniquely specifies the unit within the network. The device
object type for all devices is fixed by ASHRAE at 8. Therefore the device object instance number must be unique. The
initial Device Object identifier is set at manufacturing. The device object identifier can be read from the unit controller. The
name of the property is “Object_Identifier” and the property identifier is 75.
The initial device object instance number is 1579312. This number must be unique on the entire BACnet network. The
object instance number can be changed via the keypad display. You must cycle power for the change to take effect.
!
CAUTION
If another device in the network already has this object identifier (instance number), you must change the instance
number of one device object, so that all devices in the network have a unique device identifier.
Device Object Name
The Device Object Name uniquely specifies a device in the network. It must be unique in the network. The device name for
the MicroTech III Unit Controller device is to be determined. The device name is the “prefix” of all object names in the
MicroTech III Unit Controller. All objects include the device name and a period “.” preceding the object name.
The Device Object name is also available to the network in the device. The property name is “Object_Name” and property
identifier is 77. For a BACnet IP card, the default Object Name is POL908_###### where ###### is the last 6 digits of the
MAC address. For a BACnet MS/TP card, the default Object Name is POL904_######## where ######## is computed
from the production number and date code.
Device Object Properties
The device object contains many other informative properties as shown in Table 1.

List of BACnetCOVSubsriptions
For BACnet IP, the last 6 digits are the last 6 digits of the MAC address. The MAC address is printed a sticker affixed
to the BACnet communication module. For BACnet MS/TP, the last 8 digit are computed from the production number
printed on the bar code label affixed to the side of the module.
While the MicroTech III Unit Controller supports the entire set of object types, not all object types are used. See the
Object List for details.
The BACnet communication module and the MicroTech III Unit Controller both have their own time clocks. The date
and time read via BACnet could differ from the date and time in the unit controller the date or time is changed via the
keypad display. The two time clocks resynchronize approximately every 60-68 minutes and after every power cycle of
the unit controller or BACnet communication module.
Network Considerations
Access to Properties
Object properties are accessible from the network by specifying the device object identifier, object identifier, and the
property identifier. To access a property, you must specify the object identifier including the device object identifier or the
object name including the device object name and the property identifier.
BACnet/IP Addressing
The BACnet/Internet Protocol (BACnet/IP) address of the MicroTech III Unit Controller in a BACnet/IP network consists
of the four-octet Internet Protocol address followed by the two-octet UDP (User Datagram Protocol) port number. The
BACnet/IP address is a six-octet value analogous to a MAC address. The IP address portion of the BACnet/IP address must
be unique in the BACnet/IP network segment. The default UDP port number in the MicroTech III Unit Controller is 47808
(BAC0 in hexadecimal).
The device object of the MicroTech III Unit Controller contains a Given Internet Protocol Subnet Mask (Default is
255.255.255.0) and a default Given IP address of 127.0.0.1. The controller does support DHCP (Dynamic Host
Configuration Protocol) IP addressing which is enabled by default.
The keypad/display can be used to configure the BACnet/IP addressing. The keypad will display the current IP address
only when the network is connected.
The MicroTech III Unit Controller can be incorporated into a BACnet/IP network dedicated to BACnet devices only or an
Ethernet network shared with BACnet devices and other devices.
Shared Ethernet Networks
Integrating the MicroTech III Unit Controller into a shared Ethernet LAN requires close cooperation with the network
administrator of the shared Ethernet network. First, verify whether DHCP should or should not be enabled. If not, obtain
the IP Subnet Mask of the shared network from the network administrator. Then, obtain static IP Addresses for all
MicroTech III Unit Controllers you are integrating into the shared network. Finally obtain the address of an IP Router to use
for sending IP messages to and from the BACnet IP subnets. Once you have these, refer to Setting Unit Controller
Communication Parameters in the Basic Protocol Information section found previously in this document.
ED15112-14
11
Configuring the Unit Controller
The MicroTech III Unit Controller with attached BACnet communication module is ready to operate with the default values
of the various parameters. Default values may be changed with the unit’s keypad or via the network. Refer to the
MicroTech III Unit Controller for Commercial Rooftop, Applied Rooftop and Self-Contained Systems (OM 920) or
MicroTech III Unit Controller for Rebel Commercial Rooftop Systems (OM 1141).
BACnet MS/TP Network Addressing
The BACnet MS/TP device address (Media Access Control [MAC] address) of the MicroTech III Air Handling Unit
Controller in a BACnet Master Slave/Token Passing (MS/TP) Local Area Network (LAN) is set using the keypad/display.
Navigate to the Advanced Menus\MSTP Setup menu to change this value. You must cycle power (turn the unit controller
off and then on again) in order for the new address to take effect.
LONWORKS Networks
LONWORKS technology, developed by Echelon Corporation, is the basis for LonMark interoperable systems. This
technology is independent of the communications media. The LonMark Interoperable Association has developed standards
for interoperable LONWORKS technology systems. In particular they have published standards for HVAC equipment
including the Discharge Air Controller functional profile and the Space Comfort Controller functional profile. These
profiles specify a number of mandatory and optional standard network variables and standard configuration parameters.
This manual defines these variables and parameters available in the MicroTech III Unit Controller.
Compatibility
The MicroTech III Unit Controller with LONWORKS communication module operates in accordance with the Discharge Air
Controller (DAC) functional profile or the Space Comfort Controller (SCC) functional profile of the LonMark
Interoperability standard.
LONWORKS Variables
MicroTech III Unit Controllers incorporate LONWORKS network variables to access unit data points. The unit controller
uses LONWORKS Standard Network Variable Types (SNVT) from each profile. Some data points can be adjusted (input
network variables, nvi) (read/write attributes, e.g., setpoints) from the network and others can only be interrogated (output
network variables, nvo) (read only attributes, e.g., status information). Configuration variables (nci) are included with the
read/write attributes.
Each data point accessible from a LONWORKS network is described with a table that gives the LONWORKS Name, Profile,
SNVT Type, and SNVT Index. If the variable is a configuration variable the table also includes the SCPT Reference and the
SCPT Index.

LONWORKS Name
Each network variable has a name that you use to access the data point. This is the name of the variable from the profile. In
the example above the name network variable is nvoBldgStatPress.
Profile
The profile column designates the MicroTech III LONWORKS Communication Module that incorporates this network
variable. The variable itself may not be a standard component of that particular profile, but the communications module
does implement and it is available to the network.
SNVT Type
This column gives the name of the standard network variable type from the master list.
SNVT Index
This column gives the number of the standard network variable type from the master list.

12
ED15112-14
SCPT Index
This column gives the number of the Standard Configuration Parameter Type (SCPT) from the master list.
Network Considerations
Network Topology
Each LONWORKS Communication Module is equipped with an FTT-10A transceiver for network communications. This
transceiver allows for (1) free topology network wiring schemes using twisted pair (unshielded) cable and (2) polarity
insensitive connections at each node. These features greatly simplify installation and reduce network commissioning
problems. Additional nodes may be added with little regard to existing cable routing.
Free Topology Networks
A LONWORKS “free topology network“ means that devices (nodes) can be connected to the network in a variety of
geometric configurations. For example, devices can be daisy-chained from one device to the next, connected with stub
cables branching off from a main cable, and connected using a tree or star topology, or any of these configurations can be
mixed on the same network. Free topology segments require termination for proper transmission performance. Only one
termination is required. It may be placed anywhere along the segment. Refer to Echelon LONWORKS FTT-10A Transceiver
User’s Guide for further details).
Free Topology Restrictions
Although free topology wiring is very flexible, there are restrictions. See below for a basic summary of limitations. Refer to
the Echelon FTT-10A User’s Guide for complete details.
1. The maximum number of nodes per segment is 64.
2. The maximum total bus length depends on the wire size:
Wire Size
Maximum Node-to-Node Length
Maximum Cable Length
24 AWG
820 ft (250 m)
1476 ft (450 m)
22 AWG
1312 ft (400 m)
1640 ft (500 m)
16 AWG
1640 ft (500 m)
1640 ft (500 m)
The longest cable path between any possible pair of nodes on a segment must not exceed the maximum node-to-node
distance. If two or more paths exist between a pair of nodes (e.g., a loop topology), the longest path should be
considered. Note that in a bus topology, the longest node-to-node distance is equal to the total cable length.
1. The total length of all cable in a segment must not exceed the maximum total cable length.
2. One termination is required in each segment. It may be located anywhere along the segment.
Doubly Terminated Networks
You can extend the maximum total cable length without using a repeater by using doubly-terminated network topology. The
trade-offs are (1) this network topology must be rigorously followed during the installation and subsequent retrofits and (2)
two terminations must be installed at the ends of the bus for proper transmission performance. Refer to Echelon LONWORKS
FTT-10A Transceiver User’s Guide.
Network Cable Termination
LONWORKS network segments require termination for proper data transmission performance. The type and number of
terminations depend on network topology. Refer to Echelon LONWORKS FTT-10A Transceiver User’s Guide.
LonWorks Network Addressing
Every Neuron Chip has a unique 48-bit Neuron ID or physical address. This address is generally used only at initial
installation or for diagnostic purposes. For normal network operation, a device address is used.
Device addresses are defined at the time of network configuration. All device addresses have three parts. The first part is the
Domain ID, designating the domain. Devices must be in the same domain in order to communicate with each other. The
second part is the Subnet ID that specifies a collection of up to 127 devices that are on a single channel or a set of channels
connected by repeaters. There may be up to 255 subnets in a domain. The third part is the Node ID that identifies an
individual device within the subnet.
A group is a logical collection of devices within a domain. Groups are assembled with regard for their physical location in
the domain. There may be up to 256 groups in domain. A group address is the address that identifies all devices of the
group. There may be any number of devices in a group when unacknowledged messaging is used. Groups are limited to 64
devices if acknowledged messaging is used. A broadcast address identifies all devices within a subnet or domain.
ED15112-14
13
LONWORKS network variables for both the Discharge Air Controller and the Space Comfort Controller are defined below.
Variables are used in both the Space Comfort Controller and Discharge Air Controller profiles unless marked otherwise.
Commissioning the Network
Pressing the service pin, switch on the LONWORKS Communication Module, generates a service pin message, which
contains the Neuron ID and the program code identification of the node. A service pin message is a network message that is
generated by a node and broadcast on the network. It can be used to commission the LONWORKS network. A network
configuration tool maps device Neuron IDs to the domain/subnet/node logical addressing scheme when it creates the
network image, the logical network addresses and connection information for all devices (nodes) on the network.
External Interface File (XIF)
LonMark guidelines specify exact documentation rules so that proprietary configuration tools are not required to
commission and configure LONWORKS devices. The MicroTech III LONWORKS Communication Module is selfdocumenting so that any network management tool can obtain all the information needed over the network to connect it into
the system and to configure and manage it. An External Interface File (a specially formatted PC text file with an extension
.XIF) is also available so that any network tool can design and configure it prior to installation. XIF files are available on
http://www.DaikinApplied.com/ and www.lonmark.org.
Configuring the Unit Controller
1.
The MicroTech III Unit Controller is designed, programmed, and configured to be a rooftop or self-contained unit
controller in accordance with either the LONMARK Discharge Air Controller (DAC) or LonMark Space Comfort
Controller (SCC) functional profile. The unit is ready to operate with the default values of the various parameters set at
the factory. Default values may be changed with the unit’s keypad or via the network. See the MicroTech III Unit
Controller Operation Manual (OM 920).
Data Integrity
The integrity of some data depends on a valid network connection to maintain current values. The following data points
require a valid network connection if bound. If data points listed in Table 2 do not change after a given time, the controller
reverts to local control. In the case of the LonWorks module, the variables will revert to their default values.

Typical Application: Minimum Integration
When you have integrated the unit into your network, you can monitor and control unit operation from your workstation. At
a minimum, you can:
•
Display and monitor a minimum of important data points on your workstation display
•
Turn the unit on or off from your workstation
•
Set the schedule from your workstation and
•
Operate the unit safely
This section gives you the basic information and outlines a procedure to set up the unit for network control.
Set up the Unit for Network Control
To control the MicroTech III Unit Controller over the network, set the Control Mode function to AUTO from the unit
keypad. The keypad password (2526) is required to edit this function. For a detailed description of how to use the keypad,
refer to the MicroTech III Unit Controller for Commercial Rooftop, Applied Rooftop and Self-Contained Systems (OM
920) or MicroTech III Unit Controller for Rebel Commercial Rooftop Systems (OM 1141).
Display Important Data Points
Typical workstation displays of MicroTech III Unit Controller attributes include the following significant data points (page
number of detailed description in parenthesis). Each data point is identified with a number that also identifies it in the
Comprehensive Data Point Tables. These data points are also shaded in the comprehensive tables so that you can distinguish
them from the rest of the data points in the table. References in the text of this section also identify these data points with a
number and shading.

18 for a list of all Standard BACnet Objects available to a BACnet network. For a more detailed description of all available
data points, see the Detailed Data Point Information section.
Network Off
The unit can be turned off over the network by writing to the Application Mode. Writing AUTO to Application Mode
allows the unit controller to determine its mode of operation based on input conditions. Writing OFF to Application Mode
shuts down the unit, etc.
The Emergency Override Mode Flag can also be used to shut down the unit from the network.
Network Occupancy Scheduling
Using the keypad, set the Occupancy Mode to Auto. Schedule unit operation over the network with the Occ Scheduler input.
Switching from OCC, UNOCC, BYPASS (TntOvrd), or AUTO commands the unit into the mode you select.
ED15112-14

Alarms and Events
Alarms in a MicroTech III Unit Controller are divided into three classes: Faults, Problems, and Warnings.
•
Fault Alarms have the highest priority.
•
Problem Alarms have medium priority.
•
Warning Alarms have the lowest priority.
Notification
BACnet
MicroTech III Unit Controllers may have their alarms monitored by one of four methods: 1) individually by BACnet Binary
Values, 2) Alarm value using one BACnet Analog Value, 3) Alarm class, or 4) Notification Classes.
1.
To monitor alarms individually, read the Present_Value of the desired Binary Value object. Each alarm has its own
Binary Value object. If the Present_Value is Inactive (0), the alarm is not active. If the Present_Value is Active (1),
the alarm is active.
2.
To monitor alarms by alarm value, read the Present_Value property of the Alarm Value Analog Value object. The
Present_Value displays a value that corresponds to the highest priority alarm that is active. It is possible to have
multiple active alarms, but only the highest priority is displayed. For example, if there is a simultaneous Dirty Filter
Warning (value of 24) and a Freeze Fault (value of 252), then the Freeze Fault value of 252 will display in the
Present_Value because it is the higher priority alarm of the two. Once the Freeze Fault condition is corrected and the
fault is cleared, the next priority active alarm value (in this example, value of 24 for Dirty Filter alarm) is displayed.
The values for all alarms are described in the Alarms section tables. If the Present_Value displays a zero, there are no
active alarms.
3.
To monitor alarms by alarm class, read the Present_Value of the appropriate Analog Value object (Warnings, Problems
and Faults). The Present_Value displays a value that corresponds to the highest priority alarm that is active for that
particular alarm class. It is possible to have multiple active alarms, but only the highest priority is displayed.
4.
To monitor alarms using the Notification Class objects, see the Alarm Notification section.
LONWORKS
MicroTech III Unit Controllers may have their alarms monitored by one of two methods: 1) by using the In_alarm attribute
of nvoUnitStatus or 2) by alarm class.
1.
Alarms within MicroTech III Unit Controllers can be monitored individually by using the In Alarm attribute of the Unit
Status Network Variable Output (i.e. nvoUnitStatus_in_alarm). This attribute displays a value that corresponds to the
highest priority alarm that is active. It is possible to have multiple active alarms, but only the highest priority is
displayed in this attribute. For example, if there is a simultaneous Dirty Filter Warning (value of 24) and a Freeze Fault
(value of 252), then the Freeze Fault value of 252 will display in nvoUnitStatus_in_alarm because it is the higher
priority alarm of the two. Once the Freeze Fault condition is corrected and the fault is cleared, the next priority active
alarm value (in this example, value of 24 for Dirty Filter alarm) is displayed. The values for all alarms are described in
the Alarms section tables. If the attribute nvoUnitStatus_in_alarm displays a zero, there are no active alarms.
When the nvoUnitStatus_in_alarm attribute reads a value in the range of 1 to 99, a Warning Alarm is active. When the
attribute reads a value in the range of 100 to 199, a Problem Alarm is active. When the attribute reads a value in the
range of 200 to 255, a Fault Alarm is active.
2.
To monitor alarms by alarm class, read nvoWarnAlarm, nvoProbAlarm and nvoFaultAlarm. The value corresponds to
the highest priority alarm that is active. It is possible to have multiple active alarms, but only the highest priority is
displayed.
Clearing
BACnet
MicroTech III Unit Controllers have one Multi-State Value objects that can be used to clear alarms. All alarms of a
particular class may be cleared by writing the appropriate value to the Present Value property of ClearAlarms
(2=ClearAllFaults, 3=ClearAllProblems, 4=ClearAllWarnings). All alarms of all three classes can be cleared by writing a 5
(ClearAllAlarms) to Present_Value. Once the alarms are cleared, the Present_Value of this object goes back to None (1).
16
ED15112-14
LONWORKS
MicroTech III Unit Controllers have one variable that can be used to clear alarms; nviClearAlarms. All alarms of a
particular class may be cleared by writing the appropriate value to nviClearAlarms (1=ClearAllFaults, 2=ClearAllProblems,
3=ClearAllWarnings). All alarms of all three classes can be cleared by writing a 4 (ClearAllAlarms) to nviClearAlarms.
Once the alarms are cleared, this variable goes back to None (0).
Unit Controller Sequence of Operation
The sequence of operation for a MicroTech III Unit Controller depends on the control type. Refer to the MicroTech III Unit
Controller for Commercial Rootop, Applied Rooftop and Self-Contained Systems (OM 920) or MicroTech III Unit
Controller for Rebel Commercial Rooftop Systems (OM 1141) available on http://www.DaikinApplied.com/, for sequence
of operation details, including keypad operation.

Comprehensive Data Point Tables
The two data point tables below contain the significant information for each BACnet object or LONWORKS variable
available via the network from the MicroTech III unit controller. Additionally, refer to Table 4 for a summary of data
points specific to each MicroTech III Unit Controller model. The Detailed Data Point Information section provides a
comprehensive description of the properties, or attributes, for each point.

Detailed Data Point Information
The data points or properties (attributes) defined in this section reference data that is generated in the MicroTech III Unit
Controller. Refer to Table 4 below for a summary of data points by rooftop or self-contained model type, followed by a
detailed description of each data point.
Note:
Data points are referred to as “properties” in the BACnet protocol and “network variables” or “configuration
parameters” in the LONWORKS protocol. In this document, the text refers to this information as a “data point.” In
general, the data point is applicable to both BACnet and LONWORKS. When a data point is specific to the BACnet
protocol, the text refers to a “property.” When a data point is specific to the LONWORKS protocol, the text refers
to a “network variable” or “configuration parameter.”

This read/write configuration property enables or disables the economizer. This variable only applies if the unit is
configured for a waterside or airside economizer. In BACnet, if EconEnable is 0, then the economizer is disabled. If it is 1
and EconEnaPercent is 0, the economizer is disabled. If EconEnable is -1 (null), it is not being controlled by the network.
If EconEnable is 1 and EconEnaPercent is greater than 0, the economizer is enabled and local enable/disable decisions are
ignored (See Note). The LONWORKS point nviEconEnable has two properties; a State and a Value. When the State = 0,
economizer control through the network is disabled. When State = 1, the Economizer can be controlled through the
network. When the Value = 0 and the State = 1, the economizer is disabled through the LONWORKS network. When State =
-1 (null), the Economizer is not being controlled by the network. When the Value is greater than 0 and the State = 1, the
economizer is enabled through the LONWORKS network and local enable/disable decisions are ignored (See Note).
Note: Economizer operation is disabled locally when the unit is in dehumidification, regardless of the network Economizer
Enable settings.

Effective Setpoint Output
Keypad Menu Path Main Menu\Service Menus\Network Input Status\nvoEffSpt=
This read-only attribute monitors the effective temperature setpoint. It is always set equal to the current controlling setpoint
depending on the current unit operating state (i.e. cooling or heating). The Effective Setpoint Output depends on the
Occupied Cooling Setpoint, the Occupied Heating Setpoint, and Temperature Setpoint Input. If the Temperature Setpoint
Input (nviSetpoint) is set to a valid value:
Effective Cooling Enable Setpoint = Temperature Setpoint Input
+½(Occupied Cooling Enable Setpoint–Occupied Heating Enable Setpoint)
Effective Heating Enable Setpoint = Temperature Setpoint Input
-½(Occupied Cooling Enable Setpoint–Occupied Heating Enable Setpoint)
The Effective Setpoint Output (nvoEffectSetpt) equals Effective Heating Enable Setpoint when the control temperature is
less than Occupied Heating setpoint + [1/2(Occupied Cooling Enable Setpoint–Occupied Heating Enable Setpoint)]. It is
set equal to the Effective Cooing Enable Setpoint when the control temperature is greater than the Occupied Cooling Enable
Setpoint – [1/2(Occupied Cooling Enable Setpoint–Occupied Heating Enable Setpoint)].
If the Temperature Setpoint Input (nviSetpoint) is set to an invalid value:
Effective Cooling Enable Setpoint = Occupied Cooling Enable Setpoint
Effective Heating Enable Setpoint = Occupied Heating Enable Setpoint

Object Request
Keypad Menu Path No Keypad Equivalent
This input network variable provides the mechanism to request an operation or a mode for a functional block within a
device. A request consists of an object ID (the object_id field) and an object request (the object_request field). The object
ID is the functional block index for a functional block on the device. The Node Object functional block is index zero. The
remaining functional blocks are numbered sequentially, starting with one.
The following functions are supported:
• RQ_NORMAL - If the specified functional block was in the disabled or overridden state, this request cancels that
state, and returns the functional block to normal operation. If the functional block was already in the normal state, a
request to enter the normal state is not an error. After device reset, the state of functional blocks on the device is
application-specific. An RQ_NORMAL request that specifies the Node Object functional block index is a request for
all functional blocks in the device to leave the disabled and overridden states.
• RQ_UPDATE_STATUS - Requests the status of the specified functional block to be sent to the nvoStatus output
network variable. The state of the functional block is unchanged. An RQ_ UPDATE_STATUS request that specifies
the Node Object functional block is a request for the status of the device and all functional blocks on the device. The
status bits of the Node Object (with the exception of invalid_request and invalid_id) are defined to be the inclusiveOR of the status bits of all the other functional blocks in the device; with the possible addition of error conditions and
other conditions attributed to the device as a whole, rather than to any individual functional block. For example, if
comm_failure is supported for the Node Object, then it should be set when reporting the Node Object functional block
status whenever any of the functional blocks in the device reports communications failure, as well as when there is a
communications failure at the device level.
• RQ_REPORT_MASK - Requests a status mask reporting the status bits that are supported by the specified functional
block to be sent to the nvoStatus output network variable. A one bit in the status mask means that the device may set
the corresponding bit in the object status when the condition defined for that bit occurs. A zero bit in the status mask
means that the bit is never set by the device.

Invalid Value
Object Status
Keypad Menu Path No Keypad Equivalent
This output network variable reports the status for any functional block on a device. It is also used to report the status of the
entire device and all functional blocks on the device. A status update consists of an object ID (the object_id field) and
multiple status fields. The object ID is the functional block index as described under nviRequest. If the object ID is zero,
the status of the device itself and all functional blocks on the device is reported. The status fields are one-bit bitfields. The
only supported status fields are the report_mask, invalid_id, and invalid_request fields; all other status fields are not
supported.
• invalid_request - Set to one if an unsupported request code is received on the nviRequest input network variable.
• invalid_id - Set to one if a request is received for a functional block index that is not defined in the device. No further
checking of the request code is required when set to one.
• report_mask Set to one if an RQ_REPORT_MASK request is received by the nviRequest input network
variable, and the nvoStatus output network variable is set to contain the status mask. The status mask is an
nvoStatus value that describes the status bits that are supported beyond the three mandatory status bits. The status
mask consists of all fields in the nvoStatus output network variable, with the exception of the report_mask,
invalid_id, and invalid_request fields. A one bit in the mask means that the functional block may set the
corresponding bit in the nvoStatus output network variable when the condition defined for that bit occurs. A zero
bit means that the functional block may never set the bit.

This read/write property commands the occupancy function of the MicroTech III Unit Controller when Occupancy Mode is
set to Auto. A scheduler or a supervisory node typically sends the request. SNVT_tod_event is a structure containing three
parts.
Current_state, (required)
Next_state (optional)
Time_to_next_state (optional)
This network variable is used in conjunction with Optimal Start. If time_to_next_state is not valid, the unit controller uses
an internal calculation to determine when the unit will start. Consequently, if time_to_next_state is valid, the unit controller
uses this time to determine when the unit will start. This input is used in conjunction with nviOccManCmd (Occupancy
Mode) to determine the effective occupancy mode. Refer to Occupancy Mode for more information.

This read/write configuration property enables or disables the primary cooling. This variable only applies if the unit is
configured for mechanical cooling. In BACnet, if CoolEnable is 0, then the primary cooling is disabled. If it is 1 and
CoolEnablePct is 0, the primary cooling is disabled. If CoolEnable is -1 (null), it is not being controlled by the network. If
CoolEnable is 1 and CoolEnablePct is greater than 0, the primary cooling is enabled. When cooling is enabled,
CoolEnablePct reflects the percentage of cooling that is enabled.
The LONWORKS variable nviPriCoolEnable has two properties; a State and a Value. When the State = 0, primary cooling
control is disabled through the network. When State = -1 (null), primary cooling is not being controlled by the network.
When State = 1, the primary cooling can be controlled through the network. When the Value = 0 and the State = 1, the
primary cooling is disabled through the LONWORKS network. When the Value is greater than 0 and the State = 1, the

Remote Return/Exhaust Fan Capacity Control Flag
Keypad Menu Path Main Menu\Commission Unit\RF/EF Set-Up\RF/EF Ctrl=
This read/write property selects the return or exhaust fan airflow control. If the unit is equipped with return fan VFD and
this property is set to Tracking, the return fan airflow is controlled based on an adjustable tracking relationship between the
supply fan and return fan airflow. If this parameter is set to Building, the return or exhaust fan airflow is controlled
independently of the supply fan airflow to maintain the building static pressure at a building static pressure set point. If this
parameter is set to Speed, the return or exhaust fan airflow is controlled to a VFD speed set point set via the Return Fan
Capacity Input. If this parameter is set to OAD, the exhaust fan airflow is controlled independently of the supply fan
airflow based on the outdoor air damper position.

This read/write property selects the supply fan airflow control used on a unit equipped with a variable volume supply air
fan. If this parameter is set to Duct Static Pressure (DSP), the supply fan airflow maintains the duct static pressure at the
duct static pressure set point. If this parameter is set to Speed, the supply fan airflow is controlled to a VFD speed set via the
Supply Fan Capacity Input. If this is set to 1ZnVAV the supply fan airflow is controlled to maintain the Control
Temperature at the Occupied Cooling Setpoint or the Occupied Heating Setpoint depending on the Unit State. If this is set
to Building Static Pressure (BSP), the supply fan airflow maintains the building static pressure at the building static pressure
set point. If this is set to Carbon Dioxide (CO2), the supply fan airflow maintains the CO2 level between adjustable limits.
If this is set to Airlow (CFM), the supply fan airflow maintains the CFM level at the Outdoor Air Damper Minimum
Position setpoint.
Note: BSP, CO2 and CFM can only be selected if the unit is configured for 100% OA operation or if the unit is an SCU
unit not configured for airside economizer operation.

This read-only attribute indicates the current supply fan capacity. The BACnet property reads only the subject attribute;
however the LONWORKS variable is only a part of the LONWORKS Unit Status network variable. See Unit State for details.
This variable will read 0% whenever the fan is off. If the unit is configured as constant volume, this variable reads 100%
when the fan is on. Otherwise it will read the feedback from the VFD.
The BACnet property only applies to the subject data point. The LONWORKS variable covers six other data points: Unit

Alarms and Events
Two methods of obtaining alarm information are available in the MicroTech III Unit Controller: 1) by monitoring individual
alarms and 2) by monitoring alarms according to alarm class.
Alarms are divided into three classes: Faults, Problems, and Warnings. Fault alarms have the highest priority. Problem
alarms have the next priority. Warning alarms have the lowest priority. The alarms within each class are also prioritized.
Refer to the MicroTech III Unit Controller Operation Manual (OM 920) for a description of each alarm.
The MicroTech III Unit Controller has various ways of managing alarms, depending on the protocol. Using one of these
mechanisms, alarms can be recognized and acknowledged by alarm class or individually, and cleared from the network by
alarm class. Refer to Tables 5, 6, and 7 for details.
The following tables describe the alarm messages, indication, and method of clearing Fault, Problem, and Warning alarms.
Alarms are listed in order of priority.

Alarm Monitoring
The MicroTech III Unit Controller provides individual alarm identification through a unique value for each alarm. The
value assigned to each alarm is the same for both BACnet and LONWORKS applications.
BACnet
MicroTech III Unit Controllers may have alarms monitored by one of four methods: 1) individually by BACnet Binary
Value Objects, 2) alarm value using one BACnet Analog Values, 3) alarm class or 4) Notification Classes.
1.
To monitor alarms individually, read the Present_Value of the desired Binary Value. Each alarm has its own Binary
Value object. If the Present_Value is Inactive (0), the alarm is not active. If the Present_Value is Active (1), the alarm
is active.
2.
To monitor alarms by alarm value, read the Present_Value property of the Alarm Value Analog Value object. The
Present_Value displays a value that corresponds to the highest priority alarm that is active. It is possible to have
multiple active alarms, but only the highest priority is displayed. For example, if there is a simultaneous Dirty Filter
Warning (value of 24) and a Freeze Fault (value of 252), then the Freeze Fault value of 252 will display in the
Present_Value because it is the higher priority alarm of the two. Once the Freeze Fault condition is corrected and the
fault is cleared, the next priority active alarm value (in this example, value of 24 for Dirty Filter alarm) is displayed.
The values for all alarms are described in the Alarms section tables. If the Present_Value displays a zero, there are no
active alarms.
ED15112-14
125
3.
To monitor alarms by alarm class, read the Present_Value of the appropriate Analog Value object (Warnings, Problems
and faults). The Present_Value displays a value that corresponds to the highest priority alarm that is active. It is
possible to have multiple active alarms, but only the highest priority is displayed.
4.
To monitor alarms using the Notification Class objects, see the Alarm Notification section.
LONWORKS
MicroTech III Unit Controllers may have their alarms monitored by one of two methods: 1) using the In_alarm attribute of
nvoUnitStatus, or 2) alarm class.
1.
Alarms can be monitored individually by using the In Alarm attribute of the Unit Status Network Variable Output (i.e.
nvoUnitStatus_in_alarm). This attribute displays a value that corresponds to the highest priority alarm that is active. It
is possible to have multiple active alarms, but only the highest priority is displayed in this attribute. For example, if
there is a simultaneous Dirty Filter Warning (value of 24) and a Freeze Fault (value of 252), then the Freeze Fault value
of 252 will display in nvoUnitStatus_in_alarm because it is the higher priority alarm of the two. Once the Freeze Fault
condition is corrected and the fault is cleared, the next priority active alarm value (in this example, value of 24 for Dirty
Filter alarm) is displayed. The values for all alarms are described in the Alarms section tables. If the attribute
nvoUnitStatus_in_alarm displays a zero, there are no active alarms.
Alarms may also be monitored by alarm class if desired. When the nvoUnitStatus_in_alarm attribute reads a value in
the range of 1 to 99, a Warning Alarm is active. When the attribute reads a value in the range of 100 to 199, a Problem
Alarm is active. When the attribute reads a value in the range of 200 to 255, a Fault Alarm is active.
2.
To monitor alarms by alarm class, read nvoWarnAlarm, nvoProbAlarm and nvoFaultAlarm. The value corresponds to
the highest priority alarm that is active. It is possible to have multiple active alarms, but only the highest priority is
displayed.
Alarm and Event Notification
The MicroTech III Unit Controller has three Notification Class objects for alarms and uses intrinsic reporting which allows
the controller to generate event notifications directed to one or more recipients (maximum 20 recipients). There is one
notification class object for each class of alarms (faults, problems and warnings). You must subscribe to the notification
class objects in order to use them. The Recipient List property must indicate when and to which device notification should
be made. This is a standard BACnet data type as defined in ANSI/ASHRAE 135-2008, BACnet A Data Communication
Protocol for Building Automation and Control Networks.
The Event_Enable property of each object can be used to separately enable and disable reporting of To-OffNormal, ToFault, and To-Normal events. For example, if you do not want an event to be generated when the object returns to a normal
state after being in alarm, set the To-Normal bit of the objects Event_Enable property to 0. The tables below show the
objects that support intrinsic reporting grouped with the notification classes they report to:

A set of three flags that indicate the transition (TO-OFFNORMAL,
TO-FAULT, and TO-NORMAL) that the recipient is suitable.
If the BACnet workstation or BACnet device supports intrinsic alarming, but is unable to subscribe to the recipient list
property of the notification class object, the workstation or device can still receive alarm notification by adding its Device
Instance to the “NC Dev 1=” or “NC Dev 2=” items on the keypad/display. These items are located on the IP Setup or
MSTP Setup menus. Power must by cycled for changes to these items to take effect. Once power is cycled, the unit
controller sends out a “Who-Is” command directed at the device. If the device responds, the unit controller sends out
Unconfirmed Notifications for all alarms that are generated in the application. If the device does not respond to the Who-Is,
the unit controller will periodically send out the Who-Is until the device responds.
Alarm Clearing
BACnet
Alarms can be cleared via BACnet by setting the ClearAlms variable to value greater than 1. To clear alarms by alarm
class, change the Present_Value property to a 2 to clear all faults, a 3 to clear all problems or a 4 to clear all warnings.
Setting this variable to a 5 will clear all alarms in all three alarm classes. After the alarms are cleared, this variable will
return to None (1).
LONWORKS
Alarms can be cleared by alarm class using nviClearAlarms. To clear alarms in a particular class, set the value of
nviClearAlarms to the appropriate value (1=Clear Faults, 2=Clear Problems, 3=Clear Warnings & 4=Clear All). If the unit
is still in the alarm condition, the In Alarm attribute of the Unit Status Network Variable Output (nvoUnitStatus.in_alarm)
again reads the number corresponding to the highest priority active alarm that still exists.

These read/write properties allow subscription to event notifications. The Recipient_List conveys a list of one or more
recipients to which notifications will be sent. The Ack_Required property tells whether acknowledgment is required in
notifications generated for To-OffNormal, To-Fault, and To-Normal event transitions. The Priority conveys the priority to
be used for event notifications to To-OffNormal, To-Fault and To-Normal events. See the Alarm and Event Notification
section for more information including a list of objects that report events to this notification class.

BACnet Device Management
The following functions are specific to the BACnet device. These functions are used for maintenance and testing. A network
management tool such as VTS is typically used to issue the network commands.
DeviceCommunicationControl - Disable
The purpose of this command is to reduce network traffic for diagnostic testing of the BACnet network. When the BACnet
Communication module receives a network command to Disable communications it stops communicating information to the
network. An optional time may be specified for how long to suspend communications. The unit continues to operate during
the Disabled state.
DeviceCommunicationControl - Enable
When the BACnet Communication module receives a network command to Enable communications, MicroTech III AHU
communications to BACnet is restored.
ReinitializeDevice (Reset)
When the BACnet Communication module is capable of receiving a network ReinitializeDevice command to reboot itself
(cold start or warm start). The functionality of a cold and warm start are the same and simple reboot the BACnet
Communication module. No password is required.

BACnet File Objects
The MicroTech III unit controller contains several file objects that may be available via BACnet. Whether or not the
objects are available depends on the firmware version of the BACnet communication module attached to the unit controller.
Note:
The file objects described below are only available with BACnet firmware (BSP) version 9.26 and later. Earlier
versions of the BACnet firmware do not support these objects.
BACnet Client Config File

Some objects of this type are read only. For those objects, the Present_Value is not commandable or writable.
Changes to this property do not take effect until the power is cycled on the unit controller. After changing COV_Increment, you must
wait at least one minute before cycling power. Otherwise, this change will not be saved.
3
Thought this property is writable via BACnet, if the object is setup for Intrinsic Reporting, this value will revert to the controller value.
This is a safety feature so the network cannot disable alarms from occurring.
4
Writeable only if Out of Service is true. Also limited to multistate or analog.
5
Priority 5 is reserved for the application for commandable objects. BACnet writes at priority 5 will fail.
6
Priority 1 is reserved for the application for commandable objects. BACnet writes at priority 1 will fail.
