RG SERIES INSTALLATION MANUAL
General Installation Information
Unit Location
Safety Considerations
Locate the unit in an indoor area that allows for easy removal of
the filter and access panels. Location should have enough space
for service personnel to perform maintenance or repair. Provide
sufficient room to make water, electrical and duct connection(s). If
the unit is located in a confined space, such as a closet, provisions
must be made for return air to freely enter the space by means
of a louvered door, etc. Any access panel screws that would be
difficult to remove after the unit is installed should be removed
prior to setting the unit. On horizontal units, allow adequate room
below the unit for a condensate drain trap and do not locate the
unit above supply piping. Care should be taken when units are
located in unconditioned spaces to prevent damage from
frozen water lines and excessive heat that could damage
electrical components.
WARNING: Before performing service or maintenance
operations on a system, turn off main power switches
to the indoor unit. If applicable, turn off the accessory
heater power switch. Electrical shock could cause
personal injury.
Installing and servicing heating and air conditioning equipment
can be hazardous due to system pressure and electrical components. Only trained and qualified service personnel should install,
repair or service heating and air conditioning equipment. Untrained
personnel can perform the basic maintenance functions of cleaning coils and cleaning and replacing filters. All other operations
should be performed by trained service personnel. When working
on heating and air conditioning equipment, observe precautions in
the literature, tags and labels attached to the unit and other safety
precautions that may apply.
Installing Vertical Units
Prior to setting the unit in place, remove and discard the
compressor hold down shipping bolt located at the front of the
compressor mounting bracket.
Follow all safety codes. Wear safety glasses and work gloves. Use
a quenching cloth for brazing operations and have a fire extinguisher available.
Vertical units are available in left or right air return configurations.
Top flow vertical units should be mounted level on a vibration
absorbing pad slightly larger than the base to provide isolation
between the unit and the floor. It is not necessary to anchor the
unit to the floor (see figure below).
Moving and Storage
Move units in the normal “up” orientation. Horizontal units may
be moved and stored per the information on the packaging. Do
not stack more than three units in total height. Vertical units may
be stored one upon another to a maximum height of two units.
Do not attempt to move units while stacked. When the equipment
is received, all items should be carefully checked against the bill
of lading to be sure all crates and cartons have been received.
Examine units for shipping damage, removing the units from the
packaging if necessary. Units in question should also be internally
inspected. If any damage is noted, the carrier should make the
proper notation on the delivery receipt, acknowledging the damage.

should be pitched approximately 1/4 in. towards the drain in both
directions to facilitate the removal of condensate. Use only the
bolts provided in the kit to attach hanger brackets. The use of
longer bolts could damage internal parts.
Installing Horizontal Units
Remove and discard the compressor hold down shipping bolt
located at the front of the compressor mounting bracket prior to
setting the unit in place. Horizontal units are available with side or
end discharge.
Some applications require the installation of horizontal units on
an attic floor. In this case, the unit should be set in a full size
secondary drain pan on top of a vibration absorbing pad. The
secondary drain pan prevents possible condensate overflow or
water leakage damage to the ceiling. The secondary drain pan is
usually placed on a plywood base isolated from the ceiling joists by
additional layers of vibration absorbing material.
NOTE: Left (Right) Return Side Discharge cannot be converted to
Left (Right) Return End Discharge or vice versa, without additional
custom sheet metal parts. Horizontal units are normally suspended
from a ceiling by four (009-060 models) or five (070-072 models)

the unit by hanger bracket kits furnished with each unit.
CAUTION: Do not use rods smaller than 3/8 in.
diameter since they may not be strong enough to
support the unit. The rods must be securely anchored
to the ceiling.
Lay out the threaded rods per the Hanger Bracket Dimensions
table. Assemble the hangers to the unit as shown. Securely
tighten the brackets to the unit using the weld nuts located on
the underside of the bottom panel. When attaching the hanger
rods to the bracket, a double nut is required since vibration could
loosen a single nut. To allow filter access, install hanger brackets
as illustrated in the Hanger Bracket Locations section. The unit

RG SERIES INSTALLATION MANUAL
Duct System
An air outlet collar is provided on vertical top flow units and all
horizontal units to facilitate a duct connection. A flexible connector
is recommended for discharge and return air duct connections
on metal duct systems. Uninsulated duct should be insulated
with a minimum of 1-inch duct insulation. Application of the
unit to uninsulated ductwork in an unconditioned space is not
recommended as the unit’s performance will be adversely affected.
The duct system should be sized to handle the design airflow
quietly and efficiently. To maximize sound attenuation of the unit
blower, the supply and return plenums should include an internal
duct liner of fiberglass or constructed of ductboard for the first few
feet. On systems employing a sheet metal duct system, canvas
connectors should be used between the unit and the ductwork. If
air noise or excessive airflow is a problem, the blower speed can
be changed.
If the unit is connected to existing ductwork, check the duct system
to ensure that it has the capacity to accommodate the air required for
the unit application. If the duct is too small, as in the replacement of
heating only systems, larger ductwork should be installed. All existing
ductwork should be checked for leaks and repaired if necessary.
Water Piping
All source water connections on commercial units are fittings that
accept a male pipe thread (MPT). Insert the connectors by hand,
then tighten the fitting with a wrench to provide a leakproof joint.
When connecting to an open loop (groundwater) system, thread
any copper MPT fitting into the connector and tighten in the same
manner as described above.
The proper water flow must be provided to each unit whenever the
unit operates. To assure proper flow, use pressure/temperature
ports to determine the flow rate. These ports should be located at
the supply and return water connections on the unit. The proper
flow rate cannot be accurately set without measuring the water
pressure drop through the refrigerant-to-water heat exchanger.
Condensate Drain
On vertical units, the internal condensate drain assembly consists
of a drain tube which is connected to the drain pan, a 3/4 in. PVC
female adapter and a flexible connecting hose. The female adapter
may exit either the front or the side of the cabinet. The adapter
should be glued to the field-installed PVC condensate piping.
On vertical units, a condensate hose is inside all cabinets as a
trapping loop; therefore, an external trap is not necessary.
On horizontal units, a PVC stub or stainless steel tube is provided
for condensate drain piping connection. An external trap is required
(see below). If a vent is necessary, an open stand pipe may be
applied to a tee in the field-installed condensate piping.

Water Quality
In ground water situations where scaling could be heavy or where
biological growth such as iron bacteria will be present, a closed
loop system is recommended. The heat exchanger coils in ground
water systems may, over a period of time, lose heat exchange
capabilities due to a buildup of mineral deposits inside. These
can be cleaned, but only by a qualified service mechanic, as
special solutions and pumping equipment are required. Hot water
generator coils can likewise become scaled and possibly plugged.

In areas with extremely hard water, the owner should be informed
that the heat exchanger may require occasional flushing. Failure
to adhere to the guidelines in the water quality table could result in
loss of warranty.
Units with cupronickel heat exchangers are recommended for open
loop applications due to the increased resistance to build-up and
corrosion, along with reduced wear caused by acid cleaning.

System Cleaning and Flushing
Refill the system with clean water. Test the system water for acidity
and treat as required to leave the water slightly alkaline (pH 7.5 to
8.5). The specified percentage of antifreeze may also be added
at this time. Use commercial grade antifreeze designed for HVAC
systems only. Environol™ brand antifreeze is recommended.
Cleaning and Flushing
Prior to start up of any heat pump, the water circulating system
must be cleaned and flushed of all dirt and debris.
If the system is equipped with water shutoff valves, the supply and
return runouts must be connected together at each unit location
(This will prevent the introduction of dirt into the unit, see Flushing
with Water Shutoff Valve Equipped Systems illustration). The
system should be filled at the water make-up connection with all air
vents open. After filling, vents should be closed.
Once the system has been filled with clean water and antifreeze
(if used), precautions should be taken to protect the system
from dirty water conditions. Dirty water will result in system-wide
degradation of performance, and solids may clog valves, strainers,
flow regulators, etc. Additionally, the heat exchanger may become
clogged which reduces compressor service life and can cause
premature unit failure.
Flushing with Water Shutoff Valve Equipped Systems
In boiler/tower application, set the loop control panel set points
to desired temperatures. Supply power to all motors and start the
circulating pumps. After full flow has been established through all
components including the heat rejector (regardless of season), air
vented and loop temperatures stabilized, each of the units will be
ready for check, test and start up and for air and water balancing.

Rubber Hose
Once piping is completed between the unit pumping system and
ground loop, final purging and charging of the loop is needed. A
high pressure pump is needed to achieve adequate flow velocity
in the loop to purge air and dirt particles from the loop itself.
Antifreeze solution is used in most areas to prevent freezing. Flush
the system adequately to remove as much air as possible; then
pressurize the loop to a static pressure of 40-50 PSI (summer)
or 50-75 PSI (winter). This is normally adequate for good system
operation. Loop static pressure may decrease soon after initial
installation, due to pipe expansion and loop temperature change.
Running the unit for at least 30 minutes after the system has been
completely purged of air will allow for the “break-in” period. It may
be necessary to adjust static loop pressure (by adding water) after
the unit has run for the first time. Loop static pressure will also
fluctuate with the seasons. Pressures will be higher in the winter
months than during the cooling season. This fluctuation is normal
and should be considered when charging the system initially.
Runouts Initially
Connected Together
The contractor should start the main circulator with the pressure
reducing valve makeup open. Vents should be checked in
sequence to bleed off any trapped air and to verify circulation
through all components of the system.
As water circulates through the system, the contractor should
check and repair any leaks found in the piping system. Drain(s) at
the lowest point(s) in the system should be opened for initial flush
and blowdown, making sure water fill valves are set at the same
rate. Check the pressure gauge at the pump suction and manually
adjust the make-up water valve to hold the same positive pressure
both before and after opening the drain valves. Flushing should
continue for at least two hours, or longer if required, until drain
water is clean and clear.
Ensure the pump provides adequate flow through the unit by
checking pressure drop across the heat exchanger.
Usually 2.25-3.0 gpm of flow per ton of cooling capacity is
recommended in earth loop applications.
The supplemental heater and/or circulator pump, if used, should
be shut off. All drains and vents should be opened to completely
drain the system. Short-circuited supply and return runouts should
now be connected to the unit supply and return connections.

RG SERIES INSTALLATION MANUAL
Open Loop Ground Water Systems
Typical open loop piping is shown below. Always maintain water
pressure in the heat exchanger by placing water control valves at
the outlet of the unit to prevent mineral precipitation. Use a closed,
bladder-type expansion tank to minimize mineral formation due to
air exposure. Insure proper water flow through the unit by checking
pressure drop across the heat exchanger and comparing it to the
figures in unit capacity data tables in the specification catalog.
1.5-2 gpm of flow per ton of cooling capacity is recommended in
open loop applications. Due to only minor differences in flow rate
from low to high, only one solenoid valve should be used. The valve
should be sized for full flow.
Discharge water from the unit is not contaminated in any manner
and can be disposed of in various ways, depending on local codes,
i.e. recharge well, storm sewer, drain field, adjacent stream or
pond, etc. Most local codes forbid the use of sanitary sewer for
disposal. Consult your local building and zoning departments to
assure compliance in your area.

Typical Hot Water Generator Installation
3/4 in. x 3/4 in. x 1/2 in. Tee
To maximize the benefits of the hot water generator a minimum
50-gallon water heater is recommended. For higher demand
applications, use an 80-gallon water heater or two 50-gallon
water heaters connected in a series as shown below. Electric
water heaters are recommended. Make sure all local electrical
and plumbing codes are met for installing a hot water generator. A
water softener is recommended with hard water (greater than 10
grains or 170 total hardness).

Plumbing Installation
1. Inspect the dip tube in the water heater cold inlet for a check
valve. If a check valve is present it must be removed or
damage to the hot water generator circulator will occur.
2. Remove drain valve and fitting.
3. Thread the 3/4-inch NPT x 3-1/2-inch brass nipple into the
water heater drain port.
4. Attach the center port of the 3/4-inch FPT tee to the opposite
end of the brass nipple.
5. Attach the 1/2-inch copper to 3/4-inch NPT adaptor to the side
of the tee closest to the unit.
6. Install the drain valve on the tee opposite the adaptor.
7. Run interconnecting tubing from the tee to HWG
water out.
8. Cut the cold water “IN” line going to the water heater.
9. Insert the reducing solder tee in line with cold water “IN” line
as shown.
10. Run interconnecting copper tubing between the unit DHW
water “IN” and the tee (1/2-inch nominal). The recommended
maximum distance is 50 feet.
11. To prevent air entrapment in the system, install a vent coupling
at the highest point of the interconnecting lines.
12. Insulate all exposed surfaces of both connecting water lines
with 3/8-inch wall closed cell insulation.
NOTE: All plumbing and piping connections must comply with local
plumbing codes.

10. Make sure that any valves in the hot water generator circuit
are open.
11. Turn on the unit to heating.
12. The HWG pump should be running. When the pump is first
started, turn the venting (burping) screw (if equipped) in the
center of the pump two (2) turns open until water dribbles out,
then replace. Allow the pump to run for at least five minutes to
ensure that water has filled the circulator properly.
13. The temperature difference between the water entering
and leaving the hot water generator should be 5°F to 15°F.
The water flow should be approximately 0.4 gpm per ton of
nominal cooling.
14. Allow the unit to heat water for 15 to 20 minutes to be sure
operation is normal.
Hot Water Generator Startup
1. Make sure the power is off to the heat pump. Connect the wire
from the hot water generator pump to T1 on the contactor.
2. Close the drain valve to the water heater.
3. Open the cold water supply to the tank.
4. Open a hot water faucet in the building to bleed air from the
system. Close when full.
5. Open the pressure relief valve to bleed any remaining air from
the tank, then close.
6. If so equipped, turn the venting (burping) screw in the center of
the pump two (2) turns open (water will drip out), wait until all air is
purged from the pump, then tighten the plug. Use vent couplings to
bleed air from the lines.
7. Carefully inspect all plumbing for water leaks and correct
as required.
8. Before restoring electrical supply to the water heater, adjust the
temperature setting on the tank.
• On tanks with both upper and lower elements, the lower
element should be turned down to the lowest setting,
approximately 100°F. The upper element should be
adjusted to 120°F to 130°F. Depending upon the specific
needs of the customer, you may want to adjust the upper
element differently.
• On tanks with a single element, lower the thermostat
setting to 120°F.
9. After the thermostat(s) is adjusted, replace the access cover
and restore electrical supply to the water heater.
CAUTION: Never operate the HWG circulating
pump while dry. If the unit is placed in operation
before the hot water generator piping is connected,
be sure that the pump wires are disconnected from
the contactor.

Airflow values are with dry coil and standard filter
For wet coil performance first calculate the face velocity of the air coil (Face Velocity [fpm] = Airflow [cfm] / Face Area [sq ft]).
Then for velocities of 200 fpm reduce the static capability by 0.03 in. wg, 300 fpm by 0.08 in. wg, 400 fpm by 0.12in. wg. and 500 fpm by 0.16 in. wg.

The 5-speed ECM is a ‘Constant Torque’ ECM motor and delivers
air flow similar to a PSC but operates as efficiently as an variable
speed ECM motor. Because it’s an ECM Motor, the 5-speed ECM
can ramp slowly up or down like the variable speed ECM motor.
There are 5 possible speed taps available on the 5-speed motor
with #1 being the lowest airflow and #5 being the highest airflow.
These speed selections are preset at the time of manufacture and
are easily changed in the field if necessary.
Applying 24VAC power between any of the motor taps 1-5 (1/4
in. quick connects) and common will signal the motor to run and
regulate torque at the programmed level. The tap input voltage must
be in the range 12-33VAC. The 5-speed ECM will have less variation
over the operating static pressure range versus a PSC motor as well
as a significant watts reduction due to the high motor efficiency.
5-Speed ECM Benefits:
- High efficiency
- Soft start
- 5 speeds with up to 4 speeds on-line
- Built in logic allows air flow to change with G, Y1, Y2
and W signals
- Super efficient low airflow continuous blower
setting (G)
Thermal Protection - Motor is electronically protected.
Locked Rotor Amps - If motor speed decreases below a
programmed stall speed, the motor will shut down and after a
delay period, the control will attempt to restart the motor.
The 5-speed ECM speed tap selections are as follows:
The blue wire should be placed on the speed tap desired for the (G)
continuous blower setting – factory wired to Tap 1.
If more than one tap are energized at the same time, built in logic
gives precedence to the highest tap number and allows air flow
to change with G, Y1, Y2 and W signals. Each of those 5 speeds
has a specific ‘Torque’ value programmed into the motor for each
speed selection. As static pressure increases, airflow decreases
resulting in less torque on the rotor. The motor responds only to
changes in torque and adjusts its speed accordingly.
The red wire should be placed on the speed tap desired during
compressor operation (Y1 signal) – factory wired to Tap 3 or 4.
The gray wire is not factory wired to the motor and is tied to the wire
harness. It is field connected and can be used with 3ht/2cl thermostats
or IntelliZone to deliver the required air flow for the Y2 signal.
The 5-speed motor is powered by line voltage but the motor speed
is energized by 24VAC.
The tan wire should be placed on the speed tap desired for
auxiliary heat (W signal) – factory wired to Tap 5.
Power Connection - 3/16 in. quick connects - Line 1 (orange wire)
to L, Ground (green wire) to G, Line 2 (for 208V-230V units) to N
(brown wire).

Single or Dual Capacity Compressors
Variable Speed ECM Configuration Mode
(If Applicable)
Either single or dual capacity compressors can be operated.
The control is placed in the ECM configuration mode by
holding the pushbutton switch SW1 for 5 to 10 seconds, the
high, low, and “G” ECM speeds can be selected by following
the LED display lights. LED2 (yellow) will fast flash when
entering the ECM configuration. When setting “G” speed
LED3 (green) will be continuously lit, for low speed LED1
(red) will be continuously lit, and for high speed both LED3
(green) and LED1 (red) will be continuously lit. During the
ECM configuration mode LED2 (yellow) will flash each of
the 12 possible blower speeds 3 times. When the desired
speed is flashed press SW1, LED2 will fast flash until SW1
is released. “G” speed has now been selected. Next select
low speed, and high speed blower selections following the
same process above. After third selection has been made,
the control will exit the ECM configuration mode. Aux fan
speed will remain at default or current setting and requires
the AID Tool for adjustment.
Variable Speed ECM
Blower Motor Option (If Applicable)
A Variable Speed ECM blower motor can be driven directly
using the onboard PWM output. Four blower speeds are
available based upon the G, Y1, Y2, and W input signals to
the board. The blower speeds can be changed either by the
ECM manual configurations mode method or by using the
Aurora AID Tool directly. All four blower speeds can be set
to the same speed if desired.
5-Speed ECM Blower Motor Option (If Applicable)
A 5-Speed ECM blower motor will be driven directly using
the thermostat connections. Any of the G, Y1, or Y2/W
signals can drive any of the 5 available pre-programmed
blower speeds on the motor. All 5 Series "G" vintage units
will be wired this way at the factory.
Reset Configuration Mode
The control is placed in reset configuration mode by
holding the push button switch SW1 for 50 to 60 seconds.
This will reset all configuration settings and the EEPROM
back to the factory default settings. LED3 (green) will turn
off when entering reset configuration mode. Once LED3
(green) turns off, release SW1 and the control will reset.

Cycle with Blower - The accessory relay will cycle with
the blower output.
Lockout – when locked out, the blower will operate
continuously in “G” speed, and PSC blower motor output
will remain on. The Alarm output (ALM) and Lockout output
(L) will be turned on. The fault type identification display
LED1 (Red) shall flash the fault code. To reset lockout
conditions with SW2-8 On, thermostat inputs “Y1”, “Y2”,
and “W” must be removed for at least 3 seconds. To reset
lockout conditions with SW2-8 Off, thermostat inputs “Y1”,
“Y2”, “W”, and “DH” must be removed for at least 3 seconds.
Lockout may also be reset by turning power off for at least
30 seconds or by enabling the emergency shutdown input
for at least 3 seconds.
Cycle with Compressor - The accessory relay will cycle
with the compressor output.
Water Valve Slow Opening - The accessory relay will
cycle and delay both the blower and compressor output
for 90 seconds.
SW2-6 CC Operation – selection of single or dual capacity
compressor. On = Single Stage; Off = Dual Capacity
SW2-7 Lockout and Alarm Outputs (P2) – selection of a
continuous or pulsed output for both the LO and
ALM Outputs. On = Continuous; Off = Pulsed
SW2-8 Future Use
Lockout With Emergency Heat - if the control is locked out
in the heating mode, and a Y2 or W input is received, the
control will operate in the emergency heat mode while the
compressor is locked out. The first emergency heat output will
be energized 10 seconds after the W input is received, and the
blower will shift to high speed. If the control remains locked
out, and the W input is present, additional stage of emergency
heat will stage on after 2 minutes. When the W input is
removed, all of the emergency heat outputs will turn off, and
the ECM blower will shift to “G” speed and PSC blower motor
output will remain on.
Alarm Jumper Clip Selection
From the factory, ALM is connected to 24 VAC via JW2. By
cutting JW2, ALM becomes a dry contact connected to ALG.
Variable Speed ECM Blower Speeds
The blower speeds can be changed either by using the
ECM manual configurations mode method or by using the
Aurora AID Tool directly (see Instruction Guide: Aurora
Interface and Diagnostics (AID) Tool topic).
High Pressure – fault is recognized when the Normally
Closed High Pressure Switch, P4-9/10 opens, no matter
how momentarily. The High Pressure Switch is electrically in
series with the Compressor Contactor and serves as a hardwired limit switch if an overpressure condition should occur.
Field Selectable Options via Software
(Selectable via the Aurora AID Tool)
ECM Blower Speeds
Low Pressure - fault is recognized when the Normally
Closed Low Pressure Switch, P4-7/8 is continuously open
for 30 seconds. Closure of the LPS any time during the 30
second recognition time restarts the 30 second continuous
open requirement. A continuously open LPS shall not be
recognized during the 2 minute startup bypass time.
An ECM blower motor can be driven directly using the
onboard PWM output. Four blower speeds are available,
based upon the “G”, Y1 (low), Y2 (high), and Aux input
signals to the board. The blower speeds can be changed
either by the ECM manual configurations mode method (see
ECM Configuration Mode topic) or by using the Aurora AID
Tool directly. All four blower speeds can be set to the same
speed if desired. Aux blower speed will remain at default or
current setting and requires the AID Tool for adjustment.
Loss of Charge – fault is recognized when the Normally
Closed Low Pressure Switch, P4-7/8 is open prior to the
compressor starting.
Condensate Overflow - fault is recognized when the
impedance between this line and 24 VAC common or chassis
ground drops below 100K ohms for 30 seconds continuously.
Safety Features
The following safety features are provided to protect the
compressor, heat exchangers, wiring and other components
from damage caused by operation outside of design conditions.
Freeze Detection (Coax) - set points shall be either 30°F
or 15°F. When the thermistor temperature drops below
the selected set point, the control shall begin counting
down the 30 seconds delay. If the thermistor value rises
above the selected set point, then the count should reset.
The resistance value must remain below the selected set
point for the entire length of the appropriate delay to be
recognized as a fault. This fault will be ignored for the initial
2 minutes of the compressor run time.
Fuse – a 3 amp automotive type plug-in fuse provides
protection against short circuit or overload conditions.
Anti-Short Cycle Protection – 4 minute anti-short cycle
protection for the compressor.
Random Start – 5 to 80 second random start upon power up.
Fault Retry – in the fault condition, the control will stage off
the outputs and then “try again” to satisfy the thermostat
Y input call. Once the thermostat input calls are satisfied,
the control will continue on as if no fault occurred. If 3
consecutive faults occur without satisfying the thermostat
Y input call, then the control will go to Lockout mode.
Freeze Detection (Air Coil) - uses the FP2 input to protect
against ice formation on the air coil. The FP2 input will
operate exactly like FP1 except that the set point is 30
degrees and is not field adjustable.

RG SERIES INSTALLATION MANUAL
Controls - Aurora Base Control cont.
Over/Under Voltage Shutdown - An over/under voltage
condition exists when the control voltage is outside the
range of 18 VAC to 30 VAC. If the over/under voltage
shutdown lasts for 15 minutes, the lockout and alarm relay
will be energized. Over/under voltage shutdown is selfresetting in that if the voltage comes back within range
of 18 VAC to 30 VAC for at least 0.5 seconds, then normal
operation is restored.
Cooling Operation
In all cooling operations, the reversing valve directly tracks
the O input. Thus, anytime the O input is present, the
reversing valve will be energized.
Single Compressor Cooling, 2nd Stage (Y1, Y2, 0)
The compressor will be staged to full capacity 20 seconds
after Y2 input was received. The ECM blower will shift to high
speed 15 seconds after the Y2 input was received.
Operation Description
Dual Compressor Cooling, 2nd Stage (Y1, Y2, O)
In dual compressor operation, two ABC boards used in 24
VAC operation, there will be a Y2 call to the Y1 input on the
second ABC. The compressor will stage to full capacity 30
seconds after Y1 input is received to the second board.
Power Up - The unit will not operate until all the inputs and
safety controls are checked for normal conditions. The unit
has a 5 to 80 second random start delay at power up. Then
the compressor has a 4 minute anti-short cycle delay after
the random start delay.
Blower (G) - The blower will start immediately upon
receiving a thermostat G command. If there are no other
commands from the thermostat the ECM will run on “G”
speed until the G command is removed. Regardless of
blower input (G) from the thermostat, the blower will
remain on for 30 seconds at the end of each heating,
cooling, and emergency heat cycle.
Standby In standby mode, Y1, Y2, W, DH, and G are not
active. Input O may be active. The blower and compressor
will be off.
Heating Operation
Single Compressor Heating, 2nd Stage (Y1, Y2)
The compressor will be staged to full capacity 20 seconds
after Y2 input is received. The ECM blower will shift to high
speed seconds after the Y2 input is received.
Dehumidification (Y1, O, DH or Y1, Y2, O, DH) - When a
DH command is received from the thermostat during a
compressor call for cooling the ECM blower speed will be
reduced by 15% to increase dehumidification.
Dual Compressor Heating, 2nd Stage (Y1, Y2)
In dual compressor operation, two ABC boards used in 24
VAC operation, there will be a Y2 call to the Y1 input on the
second ABC. The compressor will stage to full capacity 30
seconds after Y1 input is received to the second board.
Emergency Shutdown - Four (4) seconds after a valid ES
input, P2-7 is present, all control outputs will be turned off
and remain off until the emergency shutdown input is no
longer present. The first time that the compressor is started
after the control exits the emergency shutdown mode,
there will be an anti-short cycle delay followed by a random
start delay. Input must be tied to common to activate.
Single Compressor Heating, 3rd Stage (Y1, Y2, W)
The hot water pump is de-energized and the first stage of
electric heat is energized 10 seconds after the W command
is received. If the demand continues the second stage of
electric heat will be energized after 5 minutes.
Continuous Blower Operation - The blower output will
be energized any time the control has a G input present,
unless the control has an emergency shutdown input
present. The blower output will be turned off when G input
is removed.
Dual Compressor Heating, 3rd Stage (Y1, Y2, W) The first stage of electric heat is energized 10 seconds
after the W command is received. If the demand continues
the second stage of electric heat will be energized after 5
minutes
Load Shed - The LS input disables all outputs with the
exception of the blower output. When the LS input has been
cleared, the anti-short cycle timer and random start timer
will be initiated. Input must be tied to common to activate.
Emergency Heat (W) - The blower will be started on “G”
speed, 10 seconds later the first stage of electric heat will
be turned on. 5 seconds after the first stage of electric
heat is energized the blower will shift to Aux speed. If the
emergency heat demand is not satisfied after 2 minutes the
second electric heat stage will be energized.
Blower (G) - The blower will start immediately upon
receiving a thermostat G command. If there are no other
commands from the thermostat the ECM will run on “G”
speed until the G command is removed. Regardless of
blower input (G) from the thermostat, the blower will
remain on for 30 seconds at the end of each heating cycle.

Unit Startup
Before Powering Unit, Check The Following:
NOTE: Remove and discard the compressor shipping bolts. The bolts can then be discarded.
• High voltage is correct and matches nameplate.
• Fuses, breakers and wire size correct.
• Low voltage wiring complete.
• Piping completed and water system cleaned and flushed.
• Air is purged from closed loop system.
• Isolation valves are open, water control valves or loop pumps wired.
• Condensate line open and correctly pitched.
• Transformer switched to 208V if applicable.
• Dip switches are set correctly.
• Blower rotates freely – foam shipping support has been removed.
• Blower speed correct.
• Air filter/cleaner is clean and in position.
• Service/access panels are in place.
• Return air temperature is between 50-80°F heating and 60-95°F cooling.
• Check air coil cleanliness to insure optimum performance. Clean as needed according to maintenance guidelines. To
obtain maximum performance the air coil should be cleaned before startup. A 10-percent solution of dishwasher
detergent and water is recommended for both sides of coil, a thorough water rinse should follow.
Startup Steps
NOTE: Complete the Equipment Start-Up/Commissioning Check Sheet during this procedure. Refer to thermostat operating instructions
and complete the startup procedure.
1. Initiate a control signal to energize the blower motor. Check blower operation.
2. Initiate a control signal to place the unit in the cooling mode. Cooling setpoint must be set below room temperature.
3. Cooling will energize after a time delay. Check for correct rotation of scroll compressors in 3 phase applications. Incorrect rotation
will cause low refrigerant pressures and possibly unusual noise. Switch any two power leads at the compressor or contactor to
reverse rotation.
4. Be sure that the compressor and water control valve or loop pump(s) are activated.
5. Verify that the water flow rate is correct by measuring the pressure drop through the heat exchanger using the P/T plugs and
comparing to the pressure drop table.
6. Check the temperature of both the supply and discharge water (Refer to Operating Parameters tables).
7. Check for an air temperature drop of 15°F to 25°F across the air coil, depending on the blower speed and entering water temperature.
8. Decrease the cooling set point several degrees and verify high-speed blower operation (Variable speed ECM only).
9. Adjust the cooling setpoint above the room temperature and verify that the compressor and water valve or loop pumps deactivate.
10. Initiate a control signal to place the unit in the heating mode. Heating set point must be set above room temperature.
11. Heating will energize after a time delay.
12. Check the temperature of both the supply and discharge water (Refer to Unit Operating Parameters tables).
13. Check for an air temperature rise of 20°F to 35°F across the air coil, depending on the blower speed and entering water temperature.
14. If auxiliary electric heaters are installed, increase the heating setpoint until the electric heat banks are sequenced on. All stages of the
auxiliary heater should be sequenced on when the thermostat is in the Emergency Heat mode. Check amperage of each element.
15. Adjust the heating setpoint below room temperature and verify that the compressor and water valve or loop pumps deactivate.
16. During all testing, check for excessive vibration, noise or water leaks. Correct or repair as required.
17. Set system to desired normal operating mode and set temperature to maintain desired comfort level.
18. Instruct the owner/operator in the proper operation of the thermostat and system maintenance.
NOTE: Be certain to fill out and forward all warranty registration papers.

8.
9.
The fuse may be open or the circuit breaker is tripped. Check electrical circuits and motor windings for shorts or grounds. Investigate
for possible overloading. Replace fuse or reset circuit breakers after fault is corrected.
Supply voltage may be too low. Check it with a volt meter.
Control system may be faulty. Check control for correct wiring of thermostat or aquastat and check the 24 volt transformer for
proper voltage.
Wires may be loose or broken. Replace or tighten.
The low pressure switch may have tripped due to one or more of the following:
a) Heating
1) Plugged heat exchanger on source side
2) Water flow source side - (Low)
3) Water too cold source side
4) Low refrigerant
b) Cooling
1) Plugged heat exchanger on load side
2) Water flow load side - (Low)
3) Water too cold load side
4) Low refrigerant
The high pressure switch may have tripped due to one or more of the following:
a) Heating
1) Plugged heat exchanger on load side
2) Low water flow load side
3) Water too warm load side
b) Cooling
1) Plugged heat exchanger on source side
2) Low water flow on source side

Refrigerant Systems
To maintain sealed circuit integrity, do not install service gauges unless unit operation appears abnormal. Compare the change in
temperature on the air side as well as the water side to the Operating Parameters tables. If the unit’s performance is not within the ranges
listed, and the airflow and water flow are known to be correct, gauges should then be installed and superheat and subcooling numbers
calculated. If superheat and subcooling are outside recommended ranges, an adjustment to the refrigerant charge may be necessary.
NOTE: Refrigerant tests must be made with hot water generator turned “OFF”. Verify that air and water flow rates are at proper levels
before servicing the refrigerant circuit.

Preventive Maintenance
Water Coil Maintenance
1. Keep all air out of the water. An open loop system should be checked to ensure that the well head is not allowing air to infiltrate the
water line. Lines should always be airtight.
2. Keep the system under pressure at all times. It is recommended in open loop systems that the water control valve be placed in the
discharge line to prevent loss of pressure during off cycles. Closed loop systems must have positive static pressure.
NOTE: On open loop systems, if the installation is in an area with a known high mineral content (125 PPM or greater) in the water, it is
best to establish with the owner a periodic maintenance schedule so the coil can be checked regularly. Should periodic coil cleaning be
necessary, use standard coil cleaning procedures which are compatible with either the cupronickel or copper water lines. Generally, the
more water flowing through the unit the less chance for scaling.
Other Maintenance
Filters
Filters must be clean to obtain maximum performance. They should be inspected monthly under normal operating conditions and be
replaced when necessary. Units should never be operated without a filter.
Condensate Drain
In areas where airborne bacteria produce a slime in the drain pan, it may be necessary to treat chemically to minimize the problem. The
condensate drain can pick up lint and dirt, especially with dirty filters. Inspect twice a year to avoid the
possibility of overflow.
Blower Motors
Blower motors are equipped with sealed ball bearings and require no periodic oiling.
Hot Water Generator Coil
See Water Coil Maintenance section above.
Air Coil
The air coil must be cleaned to obtain maximum performance. Check once a year under normal operating conditions and, if dirty, brush or
vacuum (with a brush attachment) clean. Care must be taken not to damage the aluminum fins while cleaning.
CAUTION: Fin edges are sharp.
Replacement Procedures
Obtaining Parts
When ordering service or replacement parts, refer to the model number and serial number of the unit as stamped on the serial plate
attached to the unit. If replacement parts are required, mention the date of installation of the unit and the date of failure, along with an
explanation of the malfunctions and a description of the replacement parts required.
In-Warranty Material Return
Material may not be returned except by permission of authorized warranty personnel. Contact your local distributor for warranty return
authorization and assistance.
