NOTE 1: For combined units with electric heat, use the same electric heat connections as a forced air unit.
NOTE 2: For stacked hydronic units using an aquastat, connecting Y2 is optional. A Y2 call will interrupt the lead lag timer and step into stage 2 conditioning.
NOTE 3: For combined units usings and aquastat, "AUX IN 1" is a dry contact that is reverse acting. A call for heat is generated when the contact is open.
NOTE 4: If the DHM terminal is energized during a cooling call, the fan speed slows to -10% from nominal value (Y1 - 57%, Y2 - 80%).

(Optional for Water to Water Units)
An outside air temperature sensor is optional for hydronic units
(Modine Part # 5H0835240000). The sensor should be mounted
on an outside north facing wall, under the eaves which will
provide protection from direct sunlight. It is mounted by
extending a threaded end of the ½" conduit used for wiring
through the building wall so that it protrudes at least 1" from the
wall face. The sensor can be threaded directly onto the conduit
until the unit is tight and pointing towards the ground. Remove
access cover, feed wires through and connect. Orange wire
leads are provided on the Orb board for easy field connections.
Y
(Optional for Water to Water and Combination Units)
10K sensors are recommended to control buffer tank
temperature (Modine Part # 3H0388160000). These sensors
are field wired. See wiring diagram for more detail.

Orb Display
The touchscreen LCD Display is the user interface to the
system. During operation, the screen will display various
temperatures, operation modes, menus and alarms.
The housing for the display has a green LED power light.
This light shows the user there is power to the display and the
equipment.
For hydronic, horizontal forced air, and split systems, the
display is shipped loose with a mounting bracket and must be
connected to the Orb control board. The bracket/display can
be fastened to the top of the unit using provided self-tapping
sheet metal screws or to a nearby wall using provided drywall
anchors. The supplied ribbon cable must be connected to the
back of the display and the control board (see “P17” in
Figure 3.1 or refer to Appendix A for more information).
When using the system, the display shows various buttons.
To push a button, use a quick, firm tap in the general location
of that button on the screen. Only during Calibration and
accepting all start-up values does the user need to press
and hold on the screen.

Water and Combined units are not pre-programmed from
the factory and will require the user to complete the startup
sequence. Prior to the startup sequence, the user will have to
calibrate the touchscreen. Press and hold down firmly on the
screen where the circle is located for 3-5 seconds. When the
circle moves to a new position, press and hold firmly at the new
location. If calibration is done improperly the Orb will not accept
the values and return to the first calibration screen.

9. FLC CNTRL - For stacked hydronic units, one or two flow
centers may be used. For one flow center, wire the pump
to the top unit terminals and select “SINGLE”. For two flow
centers, wire each pump to the respective unit terminals
and select “DUAL”.
18. DHW SETPT – In order to assure the domestic hot water
pump runs as much as possible it should be set at, or above
the hot water heater set point. The Orb uses a 10°F static
dead band below the set point to prevent the pump from
short cycling. The location of the temperature sensor is on
the return DHW line inside the heat pump.
Y
8. LAG TIMER (MIN) – The Lead Lag Timer is used for
stacked hydronic units only. This timer is used to start the
second stage of the system if the set point cannot be met
in that period of time. The timer can be set from 5 to 30
minutes.
10. FAN G – This allows for the adjustment of the fan when
operating in “G” signal. (Fan only). The factory setting is
33% of the nominal airflow. The installer can adjust the fan
setting -10% to +28% of the nominal airflow.
11. FAN LOW – This allows for the adjustment of the fan when
operating in “Y1” signal. (Compressor low stage). The
factory setting is 67% of the nominal airflow. The installer
can adjust the fan setting +/-10% of the nominal airflow.
12. FAN HIGH – This allows for the adjustment of the fan when
operating in “Y2” signal. (Compressor high stage). The
factory setting is 90% of the nominal airflow. The installer
can adjust the fan setting +/- 10% of the nominal airflow.
13. SCALE RANGE – Temperature readings during operation
are displayed in the selected Scale Range: Fahrenheit or
Celsius.
SE
14 & 15. ALCOHOL & PERCENTAGE – The alcohol
percentage is used to determine the freeze protection
temperature during operation. The installer selects the type
of alcohol and the percentage in the system, and then the
Orb calculates the freeze protection. If the application is an
open loop, the installer would select water and the freeze
protection would be set to 36°F.
• Water: Freeze protect 36°F
• Methanol: 10 - 25%
• Ethanol: 14 - 29%
• Propylene Glycol: 15 - 38%
16. FLC – The Orb controller has the ability to communicate
with another Orb unit for a two heat pump, single flow center
application. The heat pump to which the flow center is wired
is considered the “Master”, while the other is considered the
“Slave”. The “Slave” will send a signal to the “Master” when
the Flow Center is required to be on. When using flow center
master/slave control with a water to water unit, the water to
water unit must be configured as the master.
17. DHW PUMP – The domestic hot water pump is shipped
electronically off. If the pump is started prior to being
plumbed and filled with potable water, DAMAGE TO THE
UNIT WILL OCCUR.
19. COMPRSR – The Compressor setting selects either a
Single Stage Compressor or a Two Stage Compressor. To
determine if the unit is a single or two stage, refer to digit 8
of the model number located on the serial plate.
20. VOLTAGE – The incoming line voltage to the unit must be
input for accurate energy estimates. Measure across L1 and
L2 and input the value.
21, 22. ZONING, ZONES – If more than one forced air zone
is to be used, zoning must be enabled and the number
of zones input. (see “Zoning” on page 24 for more
information).
23, 24, 25. ZONE CFM – Enter the size of each zone which
is represented as a percentage of total unit airflow in cfm
(See “Zoning” on page 24 for more information).
26. HYD THIRD STG – A backup boiler can be connected to
the ORB through terminal "AUX OUT 4" on hydronic units.
The unit will run for the selected amount of time in minutes
(10 - 45) before the backup boiler is turned on. “AUX OUT 4”
(board location P14) is a normally open dry contact.
27. SENSOR – Select the type of control used for the hydronic
buffer tank. An Aquastat provides an ON/OFF signal to
the Orb controller, whereas the 10K Thermistor provides a
resistance to the Orb controller.
28. RELAY – When using an aquastat with a Combined unit, the
aquastat is connected through terminal "AUX IN 1". If the
aquastat is normally open, select "MAKE". If the aquastat is
normally closed, select "BREAK". “AUX IN 1” (board location
P11) is a dry contact.
29. OAT – An outside air temperature sensor can be used on
units with a hydronic buffer tank to achieve a variable set
point for the tank. On reversing water to water units using a
single buffer tank, the outside air sensor allows for automatic
changeover of the buffer tank from heating to cooling or vice
versa.
30. MODE – Conditioning Mode is used in Hydronic Reversible
& Combined applications. This allows the user to select the
initial type of conditioning that is desired. (See page 12 in
Operation on how to change mode after startup).
HEAT:
1 Tank System - The unit will maintain the tank
temperature for heating only.

Y
The cooling tank set point is maintained at the COOL TANK
MAX until the outside air temperature increases to the OAT CL
MIN temperature. As the outside air temperature increases from
70°F to 100°F, the cooling tank set point decreases linearly. At
and above the OAT CL MAX, the tank is maintained at COOL
TANK MIN temperature.
41. TANK DEADBAND – The tank deadband sets the
differential for hydronic tanks that are controlled with 10K
thermistors.
Example: If a deadband of 10°F is selected with a
heating buffer tank set point of 100°F, the unit will
operate until the set point is reached. The unit will then
be in standby until the tank temperature drops below 90°F.
42, 43. CHANGE TEMP, DEADBAND – The changeover
point is the outside air temperature used to determine
whether the system should be heating or cooling.
This Temperature is used in conjunction with the Auto
Changeover Dead Band to prevent quick switching between
conditioning modes.
Example:
CHANGE TEMP: 70°F
DEADBAND: 10°F
If the unit is in heating mode, the outside air temperature
would have to increase to 80°F before the unit changes
the single tank from the heating set point to the cooling
set point. The outside air temperature would then have to
drop below 60°F for the tank to switch back to heating.
44. PRIORITY - Combination units allow the option to set the
priority heating system to either hydronic or forced air. The
priority heating system will override the secondary system if
both are calling for heat at the same time.
45. POOL MODE – Pool mode allows the system to do forced
air cooling and hydronic heating at the same time. The flow
center shuts down and heat is rejected through the hydronic
coil instead of into the loop field. Once the hydronic tank is
satisfied, the flow center will engage and the hydronic pump
will shut down until the forced air cooling call is satisfied.
46. HOLD ACCEPT TO START – Review all startup criteria
and hold down the ACCEPT button to complete the startup
process.

31. HEAT SETPOINT – If using 10K thermistors and no outside
air temperature sensor, select the fixed set point for the
heating tank.
32. COOL SETPOINT – If using 10K thermistors and no outside
air temperature sensor, select the fixed set point for the
cooling tank.
33, 34, 35, 36. HOT TANK MIN, HOT TANK MAX, OAT
HT MIN, OAT HT MAX – The Orb allows for a variable set
point of the hydronic buffer tank based on the outside air
temperature. Maintaining a lower heating tank set point
increases energy efficiency of the system.
Heating Example:
• HOT TANK MIN 80°F
• HOT TANK MAX 110°F
• OAT HT MIN
60°F
• OAT HT MAX
30°F
Figure 10.1 - Heating Mode Outside Air Temperature

SE
The heating tank set point is maintained at the HOT TANK
MIN until the outside air temperature drops to the OAT HT MIN
temperature. As the outside air temperature drops from 60°F to
30°F, the heating tank set point increases linearly. At and below
the OAT HT MAX, the tank is maintained at HOT TANK MAX
temperature.
37, 38, 39, 40. COOL TANK MIN, COOL TANK MAX, OAT
CL MIN, OAT CL MAX – The Orb allows for a variable set
point of the hydronic buffer tank based on the outside air
temperature. Maintaining a higher cooling tank set point
increases energy efficiency of the system.
Cooling Example:
• COOL TANK MIN 30°F
• COOL TANK MAX 60°F
• OAT CL MIN 70°F
• OAT CL MAX 100°F

Operation
The LCD Touchscreen display is the window to the system.
When in normal operating mode the screen displays
temperatures, conditioning mode, conditioning staging, time,
date and any specific setup information. The temperatures
displayed are from various points throughout the equipment.
This information can provide the temperature differential through
the heat exchanger in the system for troubleshooting.
The display will eventually power off when 100 seconds of
inactivity have occurred. Every time a button is pressed, this
resets the activity timer. If the screen is off, touch the display
and the screen will turn on again.
When the system has finished a run cycle, the compressor has
a 5 minute delay to allow the pressure in the system to equalize.
If a conditioning call occurs in this 5 minute window, the amount
of time in seconds is counted down in the conditioning area of
the display.
Forced Air
The Forced Air system works off of control signals from a
conventional thermostat. These signals determine the type of
conditioning and conditioning stage of the equipment.

Water to Water
To change the operation mode after startup go to:
• MENU
• TANK SETTING
• MODE
• Select either HEAT, COOL, AUTO, CHANGEOVER, or OFF
• >>RETURN
• >>RETURN - NOTE - The Orb controller will not change the
mode unless both RETURN items are selected.
With the 10K thermistor setting, the dead band and set point
is used to determine the temperature for starting the system.
For Heating, if the tank temperature is lower than the set point
minus the dead band the system will turn on. The reverse is
applicable for Cooling.
Stacked hydronic systems work from one control panel. The
staging for the system is based on a Lead system and a Lag
system. The Lead-Lag can either start based on a timer or
based on aquastat staging. The Lead-Lag system will be
switched every 24 hours to allow for balanced run times for the
equipment. Refer to the wiring diagram for wiring the aquastat
control signals for a Lead Lag system.
Y
The Hydronic system works with either buffer tank thermistors
or aquastats. The type of sensors dictates how the main display
screen appears.
The operating mode for the equipment will also determine
system operation. If the operating mode to set to “HEAT”
or “COOL”, the system will only heat or cool. If the system
is in “AUTO”, the mode that is first to call will receive the
conditioning. Once that conditioning mode is satisfied, if
the opposite mode is also calling, it will start after the 5
minute compressor delay. If the operating mode is set to
“CHANGEOVER”, the outside air temperature along with the
dead band will determine if the system is in heating or cooling.
“OFF” mode will disable operation.

Combination Units
A combination unit will show a combination of items from both
the forced air and hydronic system status screens.
The combination system has a heat priority that will determine if
the forced air or hydronic system should run if both are calling at
the same time.
The combination system has “Pool Mode”, or dual conditioning
mode functionality. In this mode, when the system is forced air
cooling, the heat can be rejected into the hydronic buffer tank
instead of into the loop field. The system needs to be calling
for cooling from the thermostat and calling for heating from the
buffer tank for the equipment to run in this mode.

Alarms
Alarms are used to monitor various points of the equipment
and prevent the equipment damage. There are 4 types of
alarms associated with the equipment, “High Pressure”, “Low
Pressure”, “Condensate” and “Freeze Protection”. The system
can also perform a “Lockout”, which requires interaction from
the user to restart the system.
When an alarm occurs, the display will show the type of alarm
that has occurred. If the system is operating, the alarm will stop
the system and try to determine what caused the alarm. If the
system was not operating when an alarm occurs, the alarm will
still be displayed on the screen.

Low Pressure Alarm
Freeze Protect Warning
The geo (source) water out temperature is monitored to ensure
that the brine solution/water does not freeze. The temperature
must be below this value for 60 seconds for the alarm to turn on.
Once the temperature returns to above the freeze protection set
point, the system will start again.
Temperature Sensor – Out of Range
If a temperature sensor is faulty, the display will show a “*”
and “OUT” where the temperature is usually displayed. This
indicates that the value for this sensor is not communicating with
the control panel. Check the wiring or sensor for damage.
Lockout
SE
Lockout occurs when the same alarm has occurred within a 2
hour time frame. A lockout requires the user to touch the display
before the system can be restarted. Once a lockout has been
reset, it will take 2 of the same alarm for lockout to occur again.

The Orb controller is capable of controlling up to 4 forced air
zones. Unit airflow and static pressure capabilities vary by unit
type and size, refer to the Installation and Service (I&S) Manual
for more information. Ductwork should be designed to allow
each zone to handle at least 60% of the maximum unit airflow.
If the smallest zone’s ductwork is not able to be sized to handle
60% of the unit airflow, a dump zone must be designed into the
system. Modine recommends one of the following approaches
to a dump zone in a residential application:
1. Use Attic or Crawl Space: If a well-insulated attic or crawl
space is available, it must be included in the overall building
load calculation. Return grilles must be located in the attic or
crawlspace if this approach is used.
2. Use Minimum Position: If a well-insulated attic or crawl
space is not available, the larger zone dampers must be
set to stay open at a minimum position to compensate for
the smaller zones. Bypass dampers are not recommended
(barometric or powered) as they shorten the lifespan of the
unit and can cause premature compressor failure.
Components Required
1. Modine Controls System Orb Controller – Standard on Heat
Pump
2. 24 Volt Zone Dampers (By Others)
a. 4 Zone Dampers Maximum
b. 40 VA Maximum Load for All Dampers
3. 24 Volt Heat Pump Zone Thermostats (By Others)
a. Main Zone must be 4 Heat / 2 Cool
b. Zone Stats must be 1 Heat / 1 Cool
c. 3 Zone Thermostats Maximum, Plus Main Zone Thermostat
d. All thermostats must be configured for Heat Pump
Operation, per the manufacturer’s instructions
A terminal block located in the control panel is included on
forced air and combination units for easy field wiring of the zone
connections. To make a connection in the terminal block, insert
a small flat head screw driver into the square hole. Once the
screw driver is inserted far enough a stripped wire can then be
inserted in the round hole above it. Hold the wire in position
while removing the screwdriver. Gently tug the wire to make
sure the connection is tight. The Orb provides 2 damper outputs
for each zone. For Zone 1 they are labeled “D1O” (damper 1
open), and “D1C” (Damper 1 closed). The Orb provides 24VAC
to the “D1O” terminal to power the damper open, and 24VAC to
the “D1C” terminal to power the damper closed. With the open
and closed terminals, the dampers can be setup in 3 different ways:
• Power Close / Spring Open (Recommended)
• Power Open / Spring Close
• Power Open / Power Close

Sequence of Operation
During commissioning, the installer enters the number of zones
and the size of the zone, which is represented by a percentage
of total unit airflow in CFM. (See startup items 16 through 20
for how to enter the zoning information to the Orb). These zone
percentages do not control the speed of the fan. The speed of
the fan is controlled by the compressor operating speed.
Conditioning of zones operates on a first come first serve basis.
If the unit is heating Zone 1 while Zone 2 calls for cooling, the
unit will run in heating until the Zone 1 call is satisfied. Then the
unit will delay for 5 minutes before starting in cooling mode to
handle the Zone 2 call.
Emergency Heat
If the system is in Emergency Heat mode, only the Zone 1
thermostat can call for emergency heat. If the emergency heat
is on, the zone dampers will open as needed. This will cause
uneven heating of the zones to alert the homeowner as soon as
possible that there is a problem.
NOTE: The supply air temperature sensor is mounted below
the electric heating element. The air temperature rise provided
by the electric heat will not be captured on the system status
display.

The compressor operating speed and airflow is based on
the zones calling for heating or cooling and the percentage
of airflow entered by the installer during the commissioning
process.
< 67% of total airflow called
• 1st stage compressor operation
• Low speed fan, 67% of full rated airflow delivered to
zone(s) calling
> 67% of total airflow called
• 2nd stage compressor operation
• High speed fan, 90% of full rated airflow delivered to
zone(s) calling
The Orb uses a common G terminal for all zone thermostats, if
one zone calls for constant fan, all dampers will open and the
fan will come on to 25% of total unit airflow.
Zoning Example:
SE
A system with 4 zones is in standby (Zone 1 = 25%, Zone 2
= 25%, Zone 3 = 25%, Zone 4 = 25%). Zone 1 calls for heat.
The compressor goes into 1st stage operation and 67% of the
nominal airflow is delivered to Zone 1. While Zone 1 is being
heated, Zone 2 calls for heat. The total percentage of the two
zones is still less than 67%. Zone 2 damper opens while the
compressor stays in 1st stage operation and 67% of the nominal
airflow is delivered to both zones. Zone 3 calls for heat, so now
the total percentage of airflow is above 67%. The unit goes into
second stage operation, opens Zone 3 damper, and 90% of
the nominal airflow is delivered to the 3 zones. Zone 4 calls for
cooling. After all heating calls are satisfied, the compressor will
go into a 5 minute delay then restart in cooling mode.

The low voltage fuse is a 315mA replaceable fuse (Modine Part
# 5H0836540000). This fuse is designed to protect the low level
circuitry from damage. When this fuse blows, the board and the
display will not power up (no green LEDs). When replacing a
fuse, ensure all power is shut off to the equipment.
The high voltage fuses are two 240V/10A slow blow fuses
(Modine Part # 5H0836530000). These fuses are designed to
protect the high voltage components that are connected to the
control panel, which includes the flow center, blower motor,
domestic hot water pump, and hydronic pump. These two fuses
are housed in a black tower case. When replacing a fuse,

General
Remove the front and right side access panels from the unit.
The installer must determine where the Orb Display will be
located. If the display will be mounted on top of the unit, remove
the knock-out located in the top panel (see Figure 32.1 below).
If the display will be mounted remotely, the installer has the
choice of using either the knock-out located in the top panel or
in the back panel. On GFH/EFH units, the only option is to exit
the top panel.
NOTE: The ribbon cable is 6 feet long. If the display is to be
mounted remotely, the installer must ensure that the length of
the ribbon cable will be adequate to reach the desired mounting
location. If a longer cable is needed, see Table 33.1 for an
