General Installation Information
Safety Considerations
Unit Location
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
Follow all safety codes. Wear safety glasses and work
gloves. Use a quenching cloth for brazing operations and
have a fire extinguisher available.
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.
Moving and Storage
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).
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.

VERSATEC ULTRA SERIES INSTALLATION MANUAL
Installing Horizontal Units
Installing Horizontal Units
Use only the bolts provided in the kit to attach hanger
brackets. The use of longer bolts could damage internal
parts. 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. Insulate supply
plenum and use at least one 90° elbow and flexible duct
collar to reduce noise.
Remove and discard the compressor hold down shipping
screws located on the outside of the cabinet prior to
setting the unit in place. Horizontal units are available with
side or end discharge and may be easily field converted by
flipping the blower discharge panel. Horizontal units are
normally suspended from a ceiling by four 3/8 in. diameter
threaded rods. The rods are usually attached to the unit by
hanger bracket kits furnished with each unit. Lay out the
threaded rods per the dimensions below. 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, one bracket on
the filter side should be installed 180° from the position
shown in the figure below.
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.
NOTE: The unit should be pitched approximately 1/4
in. towards the drain in both directions to facilitate the
removal of condensate.

VERSATEC ULTRA 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.
CAUTION: Be sure to remove the shipping
material from the blower discharge before
connecting ductwork.
Water Piping
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.
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.
12
VERSATEC ULTRA SERIES INSTALLATION MANUAL
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.
Material
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.

Freeze Detection
For Versatec board, set SW1-2 on the printed circuit board
for applications using a closed loop antifreeze solution to
“LOOP” (15°F) [-9.4°C]. On applications using an open
loop/ground water system (or closed loop no antifreeze),
set this dip switch to “WELL” (30°F) [-1.1°C], the factory
default setting. (Refer to the Dip Switch Field Selection
table).
For FX10 board, the “red” wire must be removed from PB23 to change from “WELL”, the factory default setting, to
“LOOP”.
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 fieldinstalled condensate piping.

System Cleaning and Flushing
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.
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
Return Runout
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.

Ground Source Loop System Checkout
Runouts Initially
Connected Together
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.
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 makeup 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.
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.
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.
15
VERSATEC ULTRA 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.

loss of charge damage, and a low suction temperature
thermistor for freeze sensing. Upon a continuous 30-second
measurement of the fault (immediate for high pressure),
compressor operation is suspended, the appropriate
lockout LED begins flashing. (Refer to the “Fault Retry”
section below).
Testing
The Versatec control allows service personnel to shorten
most timing delays for faster diagnostics.
Fault Retry
All faults are retried twice before finally locking the unit out.
An output signal is made available for a fault LED at the
thermostat. The “Fault Retry” feature is designed to prevent
nuisance service calls.
Flexible Control Options
The Versatec Ultra control system is a microprocessorbased printed circuit board, (PCB), conveniently located in
the unit control box for accessibility. The microprocessor
control is specifically designed for water source heat
pumps to integrate compressors and advanced features
needed in water source heat pump applications. The
microprocessor provides control of the entire unit as well
as outputs for status modes, faults, and diagnostics. Low
voltage thermostat terminal strips provide convenient field
connections. LEDs are located on the control box to assist
the technician when servicing the unit.
Diagnostics
The Versatec control board allows all inputs and outputs to
be displayed on the LEDs for fast and simple control board
diagnosis.
Emergency Shutdown
A grounded signal to common or connecting 24 VAC to
the ES terminal places the controller into the emergency
shutdown mode. The compressor and blower operation are
suspended while in the emergency shutdown mode.
Startup
Heating Operation
The unit will not operate until all the inputs and safety
controls are checked for normal conditions. At first
powerup, a four minute delay is employed before the
compressor is energized.
Heating (Y1)
The blower motor is started immediately after the “Y1” input
is received, and the compressor is energized 10 seconds
after the “Y1” input.
Component Sequencing Delays
Cooling Operation
Components are sequenced and delayed for optimum
space conditioning performance.
Short Cycle Protection
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.
The control allows a minimum on time of 2 minutes and a
minimum off time of 5 minutes for short cycle protection.
Cooling (Y1,O)
The blower motor is started immediately after the “Y1” input
is received, and the compressor is energized 10 seconds
after the “Y1” input.
Condensate Overflow Protection
The Versatec control board incorporates an impedance
sensing liquid sensor at the top of the drain pan. Upon
a continuous 30-second sensing of the condensate,
compressor operation is suspended (see Fault Retry), and
the condensate overflow lockout LED begins flashing.
Blower (G only)
The blower motor is started immediately after the “G” input
is received; and it will remain on for 30 seconds at the end
of each heating or cooling cycle.
Safety Controls
The Versatec control receives separate signals for a high
pressure switch for safety, a low pressure switch to prevent

Lockout Conditions
Low Pressure
During lockout mode, the appropriate unit and thermostat
lockout LEDs will illuminate. The compressor, and accessory
outputs are de-energized. If the thermostat calls for heating,
emergency heat operation will occur. All other lockout
modes can be reset at the thermostat after turning the unit
off, and then on, which restores normal operation but keeps
the unit lockout LED illuminated. Interruption of power to
the unit will reset lockout without a waiting period and clear
all lockout LEDs.
This lockout mode occurs when the normally closed low
pressure switch is opened for 30 continuous seconds (set at
40 PSI).
Freeze Detection
(Water Flow)
This lockout mode occurs when the freeze thermistor
temperature is at or below the selected freeze detection
point (well 30°F or loop 15°F) for 30 continuous seconds.
High Pressure
Condensate Overflow
This lockout mode occurs when the normally closed safety
switch is opened momentarily (set at 600 PSI).
This lockout mode occurs when the condensate overflow
level has been reached for 30 continuous seconds.

To check the unit control board for proper operation:
1) Disconnect thermostat wires at the control board.
2) Jumper the desired test input (Y1, W, O or G) to the R terminal to simulate a thermostat signal.
3) If control functions properly:
• Check for thermostat and field control wiring (use the diagnostic inputs mode).
4) If control responds improperly:
• Ensure that component being controlled is functioning (compressor, blower, reversing valve, etc.).
• Ensure that wiring from control to the component is functioning (refer to the LED Definition table below and use
the diagnostic outputs mode).
• If steps above check properly, replace unit control.

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 Unit 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.

entire unit as well as input ports for Open N2, LonTalk,
BACnet (MS/TP @ 19,200 Baud rate) communication
protocols as well as an input port for a user interface. The
user interface is an accessory item that can be used to aid
in diagnostics and unit setup. A 16-pin low voltage terminal
board provides terminals for common field connections. The
FX10 Control provides:
• Operational sequencing
• High and low-pressure switch monitoring
• General lockout
• Freeze Detection
• Condensate overflow sensing
• Lockout mode control
• Emergency shutdown mode
• Random start and short cycle protection
Main FX 10 Board
Optional Plug-in Communication Modules (compatible with standard BAS protocols)

An optional Medium User Interface (MUI) for control setup
and advanced diagnostics is available with some mounting
kits, MUIK1 - Panel mount version and the MUIK2-Wall
mount version.
Zone Sensors
There are two options for zone sensors that can be used
with the FX10 control. Both sensors use a Johnson controls
A99 positive temperature coefficient type sensor. The
TAXXJ02 has a set point adjustment now which will give
the end user a +/- 5°F adjustment from the set point as
well as a push button that can be used for temporary
occupancy. The control leaves the factory set to operate
with a TAXXJ02 sensor and can be changed to read the
TAXXA04 sensor through a building automation system or
with a user interface.
The FX10 is a microprocessor based control that not
only monitors and controls the heat pump but also can
communicate any of this information back to the building
automation system (BAS). This means that not only does
the control monitor the heat pump at the unit you can also
monitor and control many the features over the BAS. This
clearly puts the FX10 in a class of its own.

The control will enumerate all fault conditions (HP, LP, CO,
LOC, and Freeze Detection) over a BAS as well as display
them on a medium user interface (MUI). HP, LP, CO and
Freeze Detection faults can all be reset over a BAS. A
Loss Of Charge fault can not be reset or bypassed until
the problem has been corrected. A MUI is invaluable as a
service tool for the building service team.
The unit can be commanded to run by a typical heat pump
thermostat or run based on heating and cooling set points
supplied by a BAS. The control board is wired with quick
connect harnesses for easy field change out of a bad
control board. All ECM2.3 variable blower speed settings
can be changed over a BAS or with a MUI. The control has
an input programmed to enable field installed emergency
heat in the event that the compressor is locked out. This
input can also be commanded on from a BAS as needed.
An alarm history can be viewed through the MUI and will
be held in memory until the unit is power cycled. Relative
humidity can be read by a 0-5VDC humidity sensor that
is displayed over the network. If you are using an ECM2.3
blower motor the control can enable dehumidification mode
based on a set point in the control. The dehumidification set
point itself can also be changed over a BAS or with a MUI.
Dehumidification mode can also be enabled by the BAS.
Because the FX10 is not factory configured to read CO2
levels, contact the factory for application assistance.

Control and Safety Feature Details
Emergency Shutdown
The emergency shutdown mode can be activated by a
command from a facility management system or a closed
contact on BI-2. The default state for the emergency
shutdown data point is off. When the emergency shutdown
mode is activated, all outputs will be turned off immediately
and will remain off until the emergency shutdown mode is
de-activated. The first time the compressor starts after the
emergency shutdown mode has been de-activated, there
will be a random start delay present.
The FX10 control has unused analog and digital inputs
for field installed items such as air temperature, water
temperature, CO2 or current status switches. The control has

VERSATEC ULTRA SERIES INSTALLATION MANUAL
Controls - FX10 (optional) cont.
Lockout Mode
Low Pressure (BI-3)
Lockout mode can be activated by any of the following fault
signals: refrigerant system high pressure, refrigerant system
low pressure, freeze detection, and condensate overflow.
When any valid fault signal remains continuously active for
the length of its recognition delay, the controller will go
into fault retry mode, which will turn off the compressor.
After the Compressor short cycle delay, the compressor
will attempt to operate once again. If three consecutive
faults occur in 60 minutes during a single heating or cooling
demand, the unit will go into lockout mode, turning off the
compressor, enabling the alarm output, and setting the
blower back to low speed operation until the controller
is reset. If the control faults due to the low pressure input
(BI-3) being open during the pre-compressor startup check,
the control will go into lockout mode immediately, disabling
the compressor from starting and enabling the alarm output
(BO-6). The lockout condition can be reset by powering
down the controller, by a command from the BAS, or by the
holding the ESC and Return keys on the MUI for 5 seconds.
The low-pressure switch shall be a normally closed (NC)
switch that monitors the systems refrigerant pressure. The
input shall be checked 15 seconds before compressor start
up to be sure the pressure switch is closed and then ignored
for the first 2 minutes after the compressor output (BO-2) is
enabled. If the switch is open continuously for (30) seconds
during compressor operation the compressor output (BO-2)
will be disabled. The compressor will not restart until the
compressor short cycle time delay has been satisfied.
Condensate Overflow
The condensate overflow sensing circuit will monitor
the condensate level as a resistance input to AI-3. If the
condensate water level rises resulting in the input resistance
rising above the set point for the recognition delay period,
the condition will be recognized as a fault. The condensate
will be subjected to a (30) second lockout delay which
requires that the fault be sensed for a continuous (30)
seconds before suspending unit operation.
Alarm Output (BO-6)
The alarm output will be enabled when the control is in the
lockout mode and will be disabled when the lockout is reset.
Test Mode
Raising the zone temperature input (AI-1) reading to 180–
220°F or by holding the ESC and down arrow keys on the
MUI for 5 seconds will put the control into test mode. In
test mode the random start delay and the compressor fixed
on delay time will both be shortened to 5 seconds and the
reversing valve will be allowed to cycle with out shutting
down the compressor. If an MUI is connected to the control
LED 8 will flash and the words “Test Mode Enabled” will be
shown on the LCD display when the control is in test mode.
Test mode will be disabled after a power cycle, 30 minute
timeout, or by holding the ESC and Up arrow keys on the
MUI.
Freeze Detection (AI-5)
The freeze detection sensor will monitor the liquid refrigerant
temperature entering the water coil in the heating mode.
If the temperature drops below the freeze detection trip
point for the recognition delay period, the condition will be
recognized as a fault. The freeze detection trip point will be
factory set for 30°F and will be field selectable for 15°F by
removing a jumper wire on BI-5. The freeze detection fault
condition will be bypassed 2 minutes at normal compressor
startup, to allow the refrigeration circuit to stabilize. If the
freeze detection sensor becomes unreliable at any time
compressor operation will immediately be suspended until
the problem is corrected. This should be displayed as an
alarm on the BAS and the MUI. This alarm will be reported a
“Water Low Temp Limit” fault.
Sequence of Operation
Power Fail Restart
When the controller is first powered up, the outputs will
be disabled for a random start delay. The delay is provided
to prevent simultaneous starting of multiple heat pumps.
Once the timer expires, the controller will operate normally.
High Pressure (BI-11)
The high-pressure switch shall be a normally closed (NC)
switch that monitors the systems refrigerant pressure. If the
input senses the high-pressure switch is open it must disable
the compressor output immediately and count the fault. The
compressor minimum on time does not apply if the highpressure switch opens. The compressor will not restart until
the compressor short cycle time delay has been satisfied.
Random Start Delay
This delay will be used after every power failure, as well as
the first time the compressor is started after the control
exits the unoccupied mode or the emergency shutdown
mode. The delay should not be less than 1 second and not
longer than 120 seconds. If the control is in test mode the
random start delay will be shortened to 5 seconds.

Compressor Fixed On Delay Time
(BO2) will be enabled and the ECM2.3 blower will
operate in medium speed. When the control receives
a Y2 command (BI-8) from the thermostat the ECM2.3
blower will operate in high speed. During the heating
cycle the reversing valve will be commanded into the
off position.
The Compressor Fixed On Delay Time will ensure that the
compressor output (B02) is not enabled for 90 seconds
after the control receives a call to start the compressor.
This delay is adjustable from 30 – 300 seconds over a BAS
or a MUI. If the control is in test mode the Compressor Fixed
On Delay Timer will be shortened to 5 seconds.
Cooling Cycle
Compressor Minimum On Delay
On a call for cooling, the blower enable output and
accessory output 2 will turn on immediately after the
random start delay timer has been satisfied. If the
compressor short cycle time delay has been satisfied,
the compressor will turn on after the blower enable and
accessory output 2 are on and the fixed compressor start
delay timers have been satisfied.
The compressor minimum on delay will ensure that the
compressor output is enabled for a minimum of two (2)
minute each time the compressor output is enabled. This
will apply in every instance except in the event the high
pressure switch is tripped or emergency shutdown then the
compressor output will be disable immediately.
Set Point Control Mode
In set point control mode the reversing valve output
will be enabled. As the temperature falls below the
cooling set point and begins to operate in the cooling
proportional band, the low capacity compressor output
(BO-2) will be enabled. A PI loop in the programming
of the control will determine when the full capacity
compressor output (BO-4) is to be enabled. The
compressor must be operating in low capacity for
a minimum of 30 seconds before the full capacity
compressor output can be enabled. During low capacity
compressor operation the ECM2.3 blower will operate in
medium speed and will operate in high speed when the
compressor is operating at full capacity.
Compressor Short Cycle Delay Time
The compressor short cycle time delay will ensure that
the compressor output will not be enabled for a minimum
of five (5) minutes after it is disabled. This allows for
the system refrigerant pressures to equalize after the
compressor is disabled.
Heating Cycle
On a call for heating, the blower enable output and
accessory output 2 will turn on immediately after the
random start delay timer has been satisfied. If the
compressor short cycle time delay has been satisfied,
the compressor will turn on after the blower enable and
accessory output 2 are on and the fixed compressor start
delay timers have been satisfied.
Thermostat Control Mode
In thermostat mode the compressor will be cycled
based on Y1 and Y2 calls from a room thermostat.
When the control receives a Y1 command (BI-7) from
the thermostat the low capacity compressor output
(BO2) will be enabled and the ECM2.3 blower will
operate in medium speed. When the control receives
a Y2 command (BI-8) from the thermostat the full
capacity compressor output will be enabled and the
ECM2.3 blower will operate in high speed. During the
cooling cycle the reversing valve will be commanded
into the “ON” position.
Auxiliary heat output can be controlled over the BAS.
Set Point Control Mode
In set point control mode the reversing valve output
will be disabled. As the temperature drops below the
heating set point and begins to operate in the heating
proportional band, the low capacity compressor output
(BO-2) will be enabled. A PI loop in the programming
of the control will determine when the full capacity
compressor output (BO-4) is to be enabled. The
compressor must be operating in low capacity for
a minimum of 30 seconds before the full capacity
compressor output can be enabled. During low capacity
compressor operation the ECM2.3 blower will operate in
medium speed and will operate in high speed when the
compressor is operating at full capacity.
ECM2.3 Blower Operation
Blower speeds will be selected through the user interface or
the facility management system. There will be a total of 12
speeds selectable with only three being selected at any one
time. The lowest numbered speed selection set to ON will
select the low-speed blower setting, the middle selection
set to ON will select the medium-speed blower setting and
the highest selection set to ON will select the high-speed
blower setting. If all selections are set to OFF the software
shall select speed setting 10 for low-speed,
Thermostat Control Mode
In thermostat mode the compressor will be cycled
based on Y1 and Y2 calls from a room thermostat.
When the control receives a Y1 command (BI-7) from
the thermostat the low capacity compressor output

11 for medium-speed, and will select speed setting 12 for
high speed. If only one selection is set to ON, that selection
will set the low-speed blower setting, the medium-speed
setting will be 11, and the high-speed setting will be speed
12. The maximum low-speed setting will be speed 10 and
the minimum high-speed setting will be speed 3. In addition
there is a low limit setting in the software to prevent the
ECM2.3 blower speed from being set below acceptable limits
for each unit size.
Accessory Outputs (BO-7 and BO-8)
Accessory Output 1 will be energized 90 seconds prior to
the compressor output being energized. Accessory Output
2 will be energized with the blower output (BO-1). When
the corresponding compressor output is turned off the
accessory output will be deactivated immediately. These
outputs are selectable for normally open or normally closed
operation through the Medium User interface or through the
Building Automation System.
ECM2.3 Blower air flow “Soft Switch Settings”
SINGLE and DUAL STAGE WATER-TO-AIR
A set of 12 “soft switches” accessible through the user
interface or building automation system are used to select
the three blower speed settings for the ECM2.3 blower
motor. The 12 soft switches work in exactly the same way as
the hardware switches used on the Premier control (Refer
to Blower Performance Data - ECM2.3 Motor for proper
settings). No more than three soft switches may be set to
the “ON” position. The first “ON” switch (the lowest number
switch) determines the “low speed blower” setting. The
second determines the “medium speed blower” setting, and
the third determines the “high speed blower” setting.
Emergency Heat/Network Enabled Output (BO5)
This output is set from the factory to enable/disable
emergency heat. If a problem occurs with the unit resulting
in the compressor being locked out in heating mode, the
control will automatically enable this output to turn on field
installed electric heat. This output is interlocked with the
blower proving input BI-6 (Blower proving sensors must
be field supplied and installed). BI-6 must be connected to
PB2 position 3 (see unit schematic) in the field if no blower
proving sensor is desired. There is a configurable parameter
available through a BAS network that must be enabled if
this output is to be commanded over the BAS network.

NOTE: This FX10 application implements an alarm history which is reset
only by cycling power . This history shows on the Alm-History page. Any
alarm showing 4+ events has occurred more than 4 times.
Alarm lock-outs are reset by cycling power, by pressing the “ESC” and
Return
keys simultaneously for a minimum of 15 seconds, or by
commanding the nviAlarmReset over the BAS network.
Test mode is enabled by holding the ‘Esc’ and Down Arrow simultaneously
for a minimum of 15 seconds and releasing. Test mode times out after 30
minutes, and may also be ended by pressing ‘ESC’ and Up Arrow
simultaneously and releasing . Test Mode bypasses the On Delay (90 sec)
and Random Start timers for quicker troubleshooting. It also allows cycling
the reversing valve without compressor shutdown.

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 Unit 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 (ECM2.3 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.

NOTE: Minimum/maximum limits are only for start-up conditions, and
are meant for bringing the space up to occupancy temperature. Units
are not designed to operate at the minimum/maximum conditions on
a regular basis. The operating limits are dependant upon three primary
factors: 1) water temperature, 2) return air temperature, and 3) ambient
temperature. When any of the factors are at the minimum or maximum
levels, the other two factors must be at the normal level for proper and
reliable unit operation.

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.
