General
YORK® Model XP units are single package heat pumps
equipped with optional factory installed electric heaters. These
units are designed for outdoor installation on a rooftop or slab.
The units are completely assembled on rigid, permanently
attached base rails. All piping, refrigerant charge, and electrical
wiring is factory installed and tested. The units require electric
power, duct connections and fixed outdoor air intake damper
(units without economizer or motorized damper option only) at
the point of installation.
Before performing service or maintenance operations on
unit, turn off main power switch to unit. Electrical shock
could cause personal injury. Improper installation,
adjustment, alteration, service or maintenance can
cause injury or property damage. Refer to this manual.
For assistance or additional information consult a
qualified installer or service agency.
The supplemental electric heaters have nickel-chrome
elements and utilize single point power connection.

methods in Manual D of the Air Conditioning Contractors of
America (ACCA) or as recommended by any other recognized
authority such as ASHRAE or SMACNA.
The scroll compressor used in this product is specifically
designed to operate with R-410A Refrigerant and cannot be
interchanged.
A closed return duct system should be used. This will not
preclude use of economizers or outdoor fresh air intake. The
supply and return air duct connections at the unit should be
made with flexible joints to minimize noise.
The supply and return air duct systems should be designed for
the CFM and static pressure requirements of the job. They
should NOT be sized to match the dimensions of the duct
connections on the unit.
Refer to Figure 5 for bottom air duct openings. Refer to Figure 8
for side air duct openings.
When fastening ductwork to side duct flanges on unit,
insert screws through duct flanges only. DO NOT insert
screws through casing. Outdoor ductwork must be
insulated and water-proofed.
Condensate Drain
Plumbing must conform to local codes. Use a sealing compound
on male pipe threads. Install a condensate drain line from the
3/4” PVC female connection on the unit to an open drain.
This system uses R-410A Refrigerant which operates at
higher pressures than R-22. No other refrigerant may be
used in this system.
The compressor also uses a polyolester (POE oil), Mobil 3MA
POE. This oil is extremely hygroscopic, meaning it absorbs
water readily. POE oil can absorb 15 times as much water as
other oils designed for HCFC and CFC refrigerants. Take all
necessary precautions to avoid exposure of the oil to the
atmosphere.
Do not leave the system open to the atmosphere. Unit
damage could occur due to moisture being absorbed by
the POE oil in the system. This type of oil is highly
susceptible to moisture absorption
POE (polyolester) compressor lubricants are known to cause
long term damage to some synthetic roofing materials.
NOTE: The condensate drain operates in a negative pressure
in the cabinet. The condensate drain line MUST be
trapped to provide proper drainage. See Figure 10.
Exposure, even if immediately cleaned up, may cause
embrittlement (leading to cracking) to occur in one year
or more. When performing any service that may risk
exposure of compressor oil to the roof, take precautions
to protect roofing.
Procedures which risk oil leakage include, but are not limited to,
compressor replacement, repairing refrigerant leaks, replacing
refrigerant components such as filter drier, pressure switch,
metering device or coil.
Figure 10: Condensate Drain
Units are shipped with compressor mountings which are
factory-adjusted and ready for operation.
Units with scroll compressors have a shipping bracket which
must be removed after the unit is set in place. See Figure 11.

The internal wiring harnesses furnished with this unit are an
integral part of the design certified unit. Field alteration to
comply with electrical codes should not be required. If any of
the wire supplied with the unit must be replaced, replacement
wire must be of the type shown on the wiring diagram and the
same minimum gauge as the replaced wire.
A disconnect must be utilized for these units. Factory installed
disconnects are available. If installing a disconnect (field
supplied or York International® supplied accessory), refer to
Figure 7 for the recommended mounting location.
Do not loosen compressor mounting bolts.
Filters
One or two-inch filters can be supplied with each unit. One-inch
filters may be used with no modification to the filter racks. Filters
must always be installed ahead of evaporator coil and must be
kept clean or replaced with same size and type. Dirty filters
reduce the capacity of the unit and result in frosted coils or
safety shutdown. Refer to physical data tables, for the number
and size of filters needed for the unit. The unit should not be
operated without filters properly installed.
Make sure that panel latches are properly positioned on
the unit to maintain an airtight seal.
Avoid damage to internal components if drilling holes for
disconnect mounting.
NOTE: Since not all local codes allow the mounting of a
disconnect on the unit, please confirm compliance with
local code before mounting a disconnect on the unit.
Electrical line must be sized properly to carry the load. USE
COPPER CONDUCTORS ONLY. Each unit must be wired with
a separate branch circuit fed directly from the meter panel and
properly fused.
Refer to Figure 12 for typical field wiring and to the appropriate
unit wiring diagram mounted inside control doors for control
circuit and power wiring information.
Power And Control Wiring
Field wiring to the unit, fuses, and disconnects must conform to
provisions of National Electrical Code (NEC), ANSI/NFPA No.
70 – Latest Edition (in U.S.A.), current Canadian Electrical
Code C221, and/or local ordinances. The unit must be
electrically grounded in accordance with NEC and CEC as
specified above and/or local codes.
When connecting electrical power and control wiring to
the unit, water-proof connectors must be used so that
water or moisture cannot be drawn into the unit during
normal operation. The above water-proofing conditions
will also apply when installing a field supplied disconnect
switch.
Voltage tolerances which must be maintained at the
compressor terminals during starting and running conditions are
indicated on the unit Rating Plate and Table 1.

subject to drafts, sun exposure or heat from electrical fixtures or
appliances. Follow the manufacturer's instructions enclosed
with thermostat for general installation procedure. Seven (7)
color-coded, insulated wires should be used to connect the
thermostat to the unit. Refer to Table 6 for control wire sizing
and maximum length.
Power Wiring Detail
Units are factory wired for the voltage shown on the unit

Minimum Position Adjustment
• Check that the damper blades move smoothly without
binding; carefully turn the Minimum Position Adjust screw
(found on the damper control module) fully clockwise and
then set the thermostat indoor fan switch to the ON
position and then OFF or energize and de-energize
terminals “R” to “G”.
• With the thermostat set to the indoor fan ON position or
terminals “R” to “G” energized, turn the Minimum Position
Adjusting screw (located on the damper control module)
counterclockwise until the desired minimum damper
position has been attained.
Enthalpy Set Point Adjustment
All of the components, including the dampers, hardware, and
mounting instructions are shipped in a single package external
from the unit and must be field assembled and installed.
• The enthalpy set point may now be set by selecting the
desired set point shown in the Enthalpy Set Point
Adjustment Figure 13. Adjust as follows:
Power exhaust is only available as a field installed accessory.
• For a single enthalpy operation carefully turn the set point
adjusting screw (found on the damper control module) to
the “A”, “B”, “C” or “D” setting corresponding to the lettered
curve of the Enthalpy Set Point Adjustment Figure 14.
Economizer And Power Exhaust Set Point
Adjustments
Remove the top rear access panel from the unit. Locate the
economizer control module, where the following adjustments
will be made.
• For a dual enthalpy operation, carefully turn the set point
adjusting screw fully clockwise past the "D" setting.
Extreme care must be exercised in turning all set point,
maximum and minimum damper positioning adjustment
screws to prevent twisting them off.

Indoor Air Quality AQ
Indoor Air Quality (indoor sensor input): Terminal AQ accepts a
+2 to +10 Vdc signal with respect to the (AQ1) terminal. When
the signal is below it's set point, the actuator is allowed to
modulate normally in accordance with the enthalpy and mixed
air sensor inputs. When the AQ signal exceeds it's set point
setting and there is no call for free cooling, the actuator is
proportionately modulated from the 2 to 10 Vdc signal, with 2
Vdc corresponding to full closed and 10 Vdc corresponding to
full open. When there is no call for free cooling, the damper
position is limited by the IAQ Max damper position setting.
When the signal exceeds it's set point (Demand Control
Ventilation Set Point) setting and there is a call for free cooling,
the actuator modulates from the minimum position to the full
open position based on the highest call from either the mixed
air sensor input or the AQ voltage input.

Phasing
XP units are properly phased at the factory. Check for proper
compressor rotation. If the blower or compressors rotate in the
wrong direction at start-up, the electrical connection to the unit
is misphased. Change the phasing of the Field Line
Connection at the factory or field supplied disconnect to
obtain proper rotation. (Scroll compressors operate in only one
direction. If the scroll is drawing low amperage, has similar
suction and discharge pressures, or producing a high noise
level, the scroll is misphased.)
Scroll compressors require proper rotation to operate
correctly. Units are properly phased at the factory. Do
not change the internal wiring to make the blower
condenser fans, or compressor rotate correctly.
Procedure for adjusting belt tension:
1. Loosen six nuts (top and bottom) A.
2. Adjust by turning (B).
3. Never loosen nuts (C).
4. Use belt tension checker to apply a perpendicular
force to one belt at the midpoint of the span as shown.
Deflection distance of 4mm (5/32”) is obtained.
To determine the deflection distance from normal position,
use a straight edge from sheave to sheave as reference
line. The recommended deflection force is as follows:
Tension new belts at the max. deflection force
recommended for the belt section. Check the belt
tension at least two times during the first 24 hours of
operation. Any retensioning should fall between the min.
and max. deflection force values.
5. After adjusting retighten nuts (A).
Blower Rotation
Check for proper supply air blower rotation. If the blower is
rotating backwards, the line voltage at the unit point of power
connection is misphased (See ‘PHASING’).
Belt Tension
The tension on the belt should be adjusted as shown in Figure 15.

CFM Static Pressure and Power-Altitude and Temperature
Corrections
The information below should be used to assist in application of
product when being applied at altitudes at or exceeding 1000
feet above sea level.
The air flow rates listed in the standard blower performance
tables are based on standard air at sea level. As the altitude or
temperature increases, the density of air decreases. In order to
use the indoor blower tables for high altitude applications,
certain corrections are necessary.
A centrifugal fan is a “constant volume” device. This means
that, if the rpm remains constant, the CFM delivered is the
same regardless of the density of the air. However, since the air
at high altitude is less dense, less static pressure will be
generated and less power will be required than a similar
application at sea level. Air density correction factors are shown
in Table 10 and Figure 16.

Figure 16: Altitude/Temperature Correction Factors
The examples below will assist in determining the airflow
performance of the product at altitude.
blower tables to select the blower speed and the BHP
requirement.
Example 1: What are the corrected CFM, static pressure, and
BHP at an elevation of 5,000 ft. if the blower performance data
is 1,400 CFM, 0.6 IWC and 0.67 BHP?
Solution: As in the example above, no temperature
information is given so 70°F is assumed.
Solution: At an elevation of 5,000 ft. the indoor blower will still
deliver 1,400 CFM if the rpm is unchanged. However, Table 11
must be used to determine the static pressure and BHP. Since
no temperature data is given, we will assume an air temperature
of 70°F. Table 10 shows the correction factor to be 0.832.
Corrected static pressure = 0.6 x 0.832 = 0.499 IWC
Corrected BHP = 0.67 x 0.832 = 0.56
Example 2: A system, located at 5,000 feet of elevation, is to
deliver 1,400 CFM at a static pressure of 1.5". Use the unit
32
The 1.5" static pressure given is at an elevation of 5,000 ft. The
first step is to convert this static pressure to equivalent sea level
conditions.
Sea level static pressure = 0.6 / .832 = 0.72"
Enter the blower table at 1,400 sCFM and static pressure of
0.72". The rpm listed will be the same rpm needed at 5,000 ft.
Suppose that the corresponding BHP listed in the table is 0.7.
This value must be corrected for elevation.
BHP at 5,000 ft. = 0.7 x .832 = 0.58

Drive Selection
1.
Determine side or bottom supply air duct application.
2.
Determine desired airflow.
3.
Calculate or measure the amount of external static pressure.
4.
Using the operating point determined from steps 1, 2 & 3, locate this point on the appropriate supply air blower performance table. (Linear
interpolation may be necessary.)
5.
Noting the RPM and BHP from step 4, locate the appropriate motor and/or drive on the RPM selection table.
6.
Review the BHP compared to the motor options available. Select the appropriate motor and/or drive.
7.
Review the RPM range for the motor options available. Select the appropriate drive if multiple drives are available for the chosen motor.
8.
Determine turns open to obtain the desired operation point.
Example
1.
2200 CFM
2.
1.6 iwg
3.
Using the supply air blower performance table below, the following data point was located: 1478 RPM & 1.82 BHP.
4.
Using the RPM selection table below, Size X and Model Y is found.
5.
1.82 BHP exceeds the maximum continuous BHP rating of the 1.5 HP motor. The 2 HP motor is required.
6.
1478 RPM is within the range of the 2 HP drive.
7.
Using the 2 HP motor and drive, 2.5 turns open will achieve 1478 RPM.

1. Motors are multi-tapped and factory wired for high speed.
The RPM of the supply air blower will depend on the required
CFM, the unit accessories or options and the static resistances
of both the supply and the return air duct systems. With this
information, the motor speed tap (direct drive) or the motor
pulley number of turns open (belt drive) can be determined from
the Blower Performance Data Tables.
Belt drive blower systems MUST be adjusted to the
specific static and CFM requirements for the application.
The belt drive blowers are NOT set at the factory for any
specific static or CFM. Adjustments of the blower speed
and belt tension are REQUIRED. Tighten blower pulley
and motor sheave set screws after these adjustments.
Re-checking set screws after 10-12 hrs. run time is
recommended.
Note the following:
1.
The supply air CFM must be within the limitations shown in
the Unit Physical Data Table 8.
2.
Pulleys can be adjusted in half turn increments.
3.
The tension on the belt should be adjusted as shown in the
Belt Adjustment Figure 15.
4.
Tighten blower pulley and motor sheave set screws after
any adjustments. Re-check set screws after 10-12 hrs. run
time is recommended.
Start the supply air blower motor. Adjust the resistances in both
the supply and the return air duct systems to balance the air
distribution throughout the conditioned space. The job
specifications may require that this balancing be done by
someone other than the equipment installer.
To check the supply air CFM after the initial balancing has been
completed:
1.
2.
Remove the two 5/16” dot plugs from the blower motor and
the filter access panels shown in Figure 7.
Insert at least 8" of 1/4 inch tubing into each of these holes
for sufficient penetration into the air flow on both sides of
the indoor coil.
Johnson Controls Unitary Products
NOTE: The tubes must be inserted and held in a position
perpendicular to the air flow so that velocity pressure
will not affect the static pressure readings.
3.
Using an inclined manometer, determine the pressure drop
across a dry evaporator coil. Since the moisture on an
evaporator coil may vary greatly, measuring the pressure
drop across a wet coil under field conditions would be
inaccurate. To assure a dry coil, the compressors should
be deactivated while the test is being run.
4.
Knowing the pressure drop across a dry coil, the actual
CFM through the unit can be determined from the curve in
Pressure Drop vs. Supply Air CFM (Figure 17).
Failure to properly adjust the total system air quantity and
static pressure can result in extensive system damage.
After readings have been obtained, remove the tubes and
reinstall the two 5/16” dot plugs that were removed in Step 1.
NOTE: De-energize the compressors before taking any test
measurements to assure a dry indoor coil.

1. Deduct these values from the available external static pressure shown in the respective Blower
Performance Tables.
2. The pressure drop through the economizer is greater for 100% outdoor air than for 100% return air. If the
resistance of the return air duct is less than 0.25 IWG, the unit will deliver less CFM during full economizer
operation.
Operation
Sequence Of Operation
For the XP series of units, the thermostat makes a circuit
between “R” and “Y1” for the first stage of cooling.
The call is passed to the Unit Control Board (UCB), which
then determines whether the requested operation is available
and, if so, which components to energize.
For heating, the thermostat makes a circuit between “R” and
“W1”. The UCB energizes the compressor and condenser fan
allowing the unit to run in heating mode. A demand defrost
control operates the defrost cycle on all 3 thru 5 ton units.
If at any time a call for both heating and cooling are present, the
heating operation will be performed. If operating, the cooling
system is halted as with a completion of a call for cooling.
Heating always takes priority.
Continuous Blower
By setting the room thermostat fan switch to "ON," the supply
air blower will operate continuously.
Intermittent Blower
With the room thermostat fan switch set to "AUTO" and the
system switch set to either the "AUTO" or "HEAT" settings, the
blower is energized whenever a cooling or heating operation is
requested. The blower is energized after any specified delay
associated with the operation.
When energized, the indoor blower has a minimum run time of
30 seconds. Additionally, the indoor blower has a delay of 10
seconds between operations.
No Outdoor Air Options
When the thermostat calls for cooling, the low-voltage control
circuit from “R” to “Y1” and “G” is completed. The compressor and
38
condenser fan motor are energized. After completing the specified
fan on delay for cooling, the UCB will energize the blower motor.
Once the thermostat has been satisfied, it will de-energize Y1. If
the compressor has satisfied its minimum run time, the
compressor and condenser fan de-energize. Otherwise, the
unit operates the cooling system until the minimum run time for
the compressor has been completed. After the compressor deenergizes, the blower is stopped following the elapse of the fan
off delay for cooling.
To be available, a compressor must not be locked-out due to a
high or low-pressure switch or freezestat trip and the anti-short
cycle delay (ASCD) must have elapsed.
Economizer With Single Enthalpy Sensor
When the room thermostat calls for cooling, the low voltage
control circuit from “R” to “G” and “Y1” is completed. The UCB
energizes the blower motor (if the fan switch on the room
thermostat is set in the “AUTO” position) and drives the
economizer dampers from fully closed to their minimum position.
If the enthalpy of the outdoor air is below the setpoint of the
enthalpy controller (previously determined), “Y1” energizes the
economizer. The dampers will modulate to maintain a constant
supply air temperature as monitored by the discharge air sensor.
If the outdoor air enthalpy is above the setpoint, “Y1” energizes
the compressor and condenser fan motor only.
Once the thermostat has been satisfied, it will de-energize “Y1”. If
the compressor has satisfied its minimum run time, the
compressor and condenser fan are de-energized. Otherwise, the
unit operates the cooling system until the minimum run times for
the compressor has been completed. After the compressor deenergizes, the blower is stopped following the elapse of the fan
off delay for cooling, and the economizer damper goes to the
closed position. If the unit is in continues fan operation the
economizer damper goes to the min. position.
Johnson Controls Unitary Products
444463-YIM-F-0212
Economizer With Dual Enthalpy Sensors
The operation with the dual enthalpy sensors is identical to the
single sensor except that a second enthalpy sensor is mounted
in the return air. This return air sensor allows the economizer to
choose between outdoor air and return air, whichever has the
lowest enthalpy value, to provide maximum operating efficiency.
Economizer With Power Exhaust
A unit equipped with an economizer (single or dual enthalpy)
and a power exhaust operates as specified above with one
addition. The power exhaust motor is energized 45 seconds
after the actuator position exceeds the exhaust fan set point on
the economizer control. When the power exhaust is operating,
the second stage of mechanical cooling will not operate. As
always, the "R" to "G" connection provides minimum position
but does not provide power exhaust operation.
Motorized Outdoor Air Dampers
This system operation is the same as the units with no outdoor
air options with one exception. When the “R” to “G” circuit is
complete, the motorized damper drives open to a position set
by the thumbwheel on the damper motor. When the “R” to “G”
circuit is opened, the damper spring returns fully closed.
Cooling Operation Errors
Each cooling system is monitored for operation outside of the
intended parameters. Errors are handled as described below. All
system errors override minimum run times for compressors.
High-Pressure Limit Switch
During cooling operation, if a high-pressure limit switch opens,
the UCB will de-energize the compressor, initiate the ASCD
(Anti-short cycle delay), and stop the condenser fan. If the call
for cooling is still present at the conclusion of the ASCD, the
UCB will re-energize the compressor.
Should a low-pressure switch open three times within one hour
of operation, the UCB will lock-out the compressor and flash a
code (Table 19).
Freezestat
During cooling operation, if a freezestat opens, the UCB will deenergize the compressor, initiate the ASCD, and stop the
condenser fan. If the call for cooling is still present at the
conclusion of the ASCD, the UCB will re-energize the halted
compressor.
Should a freezestat open three times within two hours of
operation, the UCB will lock-out the associated compressor and
flash a code (Table 19).
Low Ambient Cooling
To determine when to operate in low ambient mode, the UCB
has a pair of terminals connected to a temperature-activated
switch set at 45ºF. When the low ambient switch is closed and
the thermostat is calling for cooling, the UCB will operate in the
low ambient mode.
Low ambient mode operates the compressors in this manner:
10 minutes on, 5 minutes off. The indoor blower is operated
throughout the cycle. The 5-minute off period is necessary to
defrost the indoor coil.
Low ambient mode always begins with compressor operation.
Compressor minimum run time may extend the minutes of
compressor operation. The defrost cycle will begin immediately
following the elapse of the minimum run time.
When operating in low ambient mode, the UCB will not lockout
the compressors due to a freezestat trip. However, a freezestat
trip will de-energize the associated compressor. If the call for
cooling is still present at the end of the ASCD and the freezestat
has closed, the unit will resume operation.
Safety Controls
Should a high-pressure switch open three times within two
hours of operation, the UCB will lock-out the associated
compressor and flash a code (see Table 19).
The unit control board monitors the following inputs for each
cooling system:
Low-Pressure Limit Switch
1.
A suction line freezestat to protect against low evaporator
temperatures due to a low airflow or a low return air
temperature, (opens at 26 ± 5 °F and resets at 38 ± 5°F).
2.
A high-pressure switch to protect against excessive
discharge pressures due to a blocked condenser coil or a
condenser motor failure, (opens at 625 ± 25 psig).
3.
A low-pressure switch to protect against loss of refrigerant
charge, (opens at 22 ± 5 psig).
The low-pressure limit switch is not monitored during the initial
30 seconds of a cooling system's operation. For the following
30 seconds, the UCB will monitor the low-pressure switch to
ensure it closes. If the low-pressure switch fails to close after
the 30-second monitoring phase, the UCB will de-energize the
compressor, initiate the ASCD, and stop the condenser fan.
Once the low-pressure switch has been proven (closed during the
30-second monitor period described above), the UCB will monitor
the low-pressure limit switch for any openings. If the low-pressure
switch opens for greater than 5 seconds, the UCB will de-energize
the compressor, initiate the ASCD, and stop the condenser fan.
The above pressure switches are hard-soldered to the unit. The
refrigeration systems are independently monitored and
controlled. On any fault, only the associated system will be
affected by any safety/preventive action.
If the call for cooling is still present at the conclusion of the
ASCD, the UCB will re-energize the compressor.
The unit control board monitors the temperature limit switch of
electric heat units and the temperature limit switch and the gas
valve of gas furnace units.

444463-YIM-F-0212
Compressor Protection
In addition to the external pressure switches, the compressor
also has inherent (internal) protection. If there is an abnormal
temperature rise in a compressor, the protector will open to shut
down the compressor. The UCB incorporates features to
minimize compressor wear and damage. An Anti-Short Cycle
Delay (ASCD) is utilized to prevent operation of a compressor
too soon after its previous run. Additionally, a minimum run time
is imposed any time a compressor is energized.
The ASCD is initiated on unit start-up and on any compressor
reset or lock-out.
Flash Codes
The UCB will initiate a flash code associated with errors within
the system. Refer to UNIT CONTROL BOARD FLASH CODES
Table 19.
Reset
Remove the call for cooling, by raising thermostat setting higher
than the conditioned space temperature. This resets any
pressure or freezestat flash codes.
Heating Sequence Of Operations
With or Without Electric Heat
When the thermostat calls for the first stage of heating, the low
voltage control circuit is completed between “R” and “W1”. The
24vac signal is passed through the UCB to the “Y” contact on
the Defrost Control (DC) assuring the reversing valve cannot be
energized, except during defrost. If the ASCD timer is satisfied
the UCB will energize compressor contactor M1.
If the compressor alone cannot satisfy the heating
requirements, a second stage call from the thermostat
completes the circuit between “R” and “W2”. This 24vac signal
is passed through the UCB to the electric heat section (if
available). The total available kW of electric heat will be
energized on a call for “W2”.
inhibit feature prohibits defrost if the coil temperature is above
40°F.
Forced Defrost
A forced-defrost feature puts the system into a defrost period
every 6 hours and 4 minutes to recirculate lubricants, unless the
coil temperature is above 40°F. All defrost timing occurs only
while the compressor is on.
During the defrost mode, the defrost control will provide a 24
volt signal from terminal “W1/66” to the fan control terminal
“W2”. This signal will energize electric heat stage 1, if the unit is
so equipped.
For trouble shooting purposes, the defrost cycle can be
manually initiated by shorting the “TEST” pins together for 5
seconds. Defrost will terminate normally during the “TEST”
mode.
Defrost Mode (5 Ton)
As mentioned earlier, the defrost control (DC) utilizes a time/
temperature defrost scheme. The following two conditions must
be met before the DC will enter a defrost mode:
The defrost thermostat (SD) must be closed. This normally
open thermostat is mounted on the liquid line and is set to close
at 28 ± 4°F.
Once the defrost thermostat closes, the defrost control starts a
run timer that must be satisfied before defrost can begin. This is
accumulated compressor run time. The selection pin is factory
set at 60 minutes, but is field adjustable to 30, 60 or 90 minutes.
When the DC enters the defrost mode, it’s on-board defrost
relay is powered. This energizes the reversing valve, deenergizes the condenser fan motor and energizes the unit’s
optional electric heater. The DC remains in defrost mode until
either of the following two conditions is met:
1.
The liquid line thermostat is open. It is set to open at 55 ±
4°F.
Defrost Mode (3 thru 4 Ton)
2.
The maximum defrost run time of 10 minutes is met.
The demand defrost control implements a temperature
differential (”delta-T”) demand defrost algorithm. The heat pump
is allowed to operate in the heating mode until the combination
of outdoor ambient and outdoor coil temperatures indicate that
defrosting is necessary. When coil temperature is below the
initiate point for the ambient temperature continuously for 4-1/2
minutes, the heat pump is put into a defrost cycle. This 4-1/2
minute timer eliminates unnecessary defrost cycles caused by
refrigeration surges such as those that occur at the start of a
heating cycle.
Forced Defrost
A timed inhibit feature prevents the system from responding to
a call for defrost less than 20 minutes after the initiation of the
previous defrost. After the 20 minute inhibit time has expired,
temperature conditions must call for defrost continuously for 41/2 minutes before a defrost cycle is initiated. A temperature
40
The processor on the defrost board is only energized when the
defrost sensor (DS) is closed.
To create a forced defrost:
1.
The DS must either be closed or a jumper must be placed
across the DFS terminals on the board.
2.
Place a jumper across the test pin terminals on the board.
Depending on the selected defrost minimum run time of 30,
60 or 90 minutes, the board will go into defrost in 7.5, 15 or
22.5 seconds.
The DC will remain in defrost until the jumpers across
the DS and the test pin terminals are removed.
Johnson Controls Unitary Products
444463-YIM-F-0212
Once the jumpers are removed, the board then terminates
defrost when the DS opens or a maximum of 10 minutes
after the test pin jumper is removed, whichever comes first.
Safety Controls
The electric heat control circuit includes the following safety
controls:
temperature swing in the conditioned space. Reducing the
value below the correct setpoint will give shorter “ON” cycles
and may result in the lowering of the temperature within the
conditioned space. Refer to Table 18 for the required electric
heat anticipator setting.

This control is located inside the heater compartment and is set
to open at the temperature indicated in the Electric Heat Limit
Setting Table 17. It resets automatically. The limit switch
operates when a high temperature condition, caused by
inadequate supply air flow occurs, thus shutting down the
heater and energizing the blower.

Troubleshooting
Troubleshooting of components may require opening
the electrical control box with the power connected to
the unit. Use extreme care when working with live
circuits! Check the unit nameplate for the correct line
voltage and set the voltmeter to the correct range before
making any connections with line terminals.
When not necessary, shut off all electric power to the
unit prior to any of the following maintenance
procedures so as to prevent personal injury.
Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and
dangerous operation which could cause injury to person
and/or damage unit components. Verify proper
operation after servicing.
5.
If M2 is not pulled in, check for 24 volts at the M2 coil. If 24
volts are present at M2 but M2 is not pulled in, replace the
contactor.
6.
Failing the above, if there is line voltage supplied at M2, M2
is pulled in, and the supply air blower motor still does not
operate, replace the motor.
7.
If 24 volts is not present at M2, check that 24 volts is
present at the UCB supply air blower motor terminal,
“FAN”. If 24 volts is present at the FAN, check for loose
wiring between the UCB and M2.
8.
If 24 volts is not present at the “FAN” terminal, check for 24
volts from the room thermostat. If 24 volts are not present
from the room thermostat, check for the following:
a. Proper operation of the room thermostat (contact
between R and G with the fan switch in the ON position
and in the AUTO position during operation calls).
b. Proper wiring between the room thermostat and the
UCB.
c. Loose wiring from the room thermostat to the UCB.
9.
If 24 volts is present at the room thermostat but not at the
UCB, check for proper wiring between the thermostat and
the UCB, i.e. that the thermostat G terminal is connected to
the G terminal of the UCB, and for loose wiring.
10. If the thermostat and UCB are properly wired, replace the
UCB.
On a call for cooling, the supply air blower motor is operating
but the compressor is not (the room thermostat fan switch is in
the “AUTO” position).
1.
If installed, check the position of the economizer blades. If
the blades are open, the economizer is providing free
cooling and the compressors will not immediately operate.
If both stages of cooling are requested simultaneously and
the economizer provides free cooling, following a short
delay the compressor will be energized unless it is locked
out, unless this option has been disabled through computer
communications.
2.
If no economizer is installed or the economizer is not
opening to provide free cooling and the compressor does
not energize on a call for cooling, check for line voltage at
the compressor contactor, M1, and that the contactor is
pulled in. Check for loose wiring between the contactor and
the compressor.
On calls for cooling, if the compressors are operating but the
supply air blower motor does not energize after a short delay
(the room thermostat fan switch is in the “AUTO” position).
1.
Turn the thermostat fan switch to the ON position. If the
supply air blower motor does not energize, go to Step 3.
2.
If the blower motor runs with the fan switch in the ON
position but will not run after the compressor has energized
when the fan switch is in the AUTO position, check the
room thermostat for contact between R and G in the AUTO
position during calls for cooling.
3.
If the supply air blower motor does not energize when the
fan switch is set to ON, check that line voltage is being
supplied to the contacts of the M2, contactor, and that the
contactor is pulled in. Check for loose wiring between the
contactor and the supply air blower motor.
If M1 is pulled in and voltage is supplied at M1, lightly touch
the compressor housing. If it is hot, the compressor may be
off on inherent protection. Cancel any calls for cooling and
wait for the internal overload to reset. Test again when
cool.
4.
If M1 is not pulled in, check for 24 volts at the M1 coil. If 24
volts are present and M1 is not pulled in, replace the
contactor.
3.
4.
42
If M2 is pulled in and voltage is supplied to M2, lightly touch
the supply air blower motor housing. If it is hot, the motor
may be off on internal protection. Cancel any thermostat
Johnson Controls Unitary Products
444463-YIM-F-0212
5.
Failing the above, if voltage is supplied at M1, M1 is pulled
in, and the compressor still does not operate, replace the
compressor.
6.
If 24 volts is not present at M1, check for 24 volts at the
UCB terminal, C1. If 24 volts is present, check for loose
wiring between C1 and the compressor contactor.
7.
If 24 volts is not present at the C1 terminal, check for 24
volts from the room thermostat at the UCB Y1 terminal. If
24 volts is not present from the room thermostat, check for
the following:
a. 24 volts at the thermostat Y1 terminal
b. Proper wiring between the room thermostat and the
UCB, i.e. Y1 to Y1, Y2 to Y2
c. Loose wiring from the room thermostat to the UCB.
8.
9.
If 24 volts is present at the UCB Y1 terminal, the
compressor may be out due to an open high-pressure
switch, low-pressure switch, or freezestat. Check for 24
volts at the HPS1, LPS1, and FS1 terminals of the UCB. If
a switch has opened, there should be a voltage potential
between the UCB terminals, e.g. if LPS1 has opened, there
will be a 24-volt potential between the LPS1 terminals.
If 24 volts is present at the UCB Y1 terminal and none of
the protection switches have opened, the UCB may have
locked out the compressor for repeat trips. The UCB
should be flashing an alarm code. If not, press and release
the ALARMS button on the UCB. The UCB will flash the
last five alarms on the LED. If the compressor is locked
out, cancel any call for cooling. This will reset any
compressor lock outs.
NOTE: While the above step will reset any lockouts, the
compressor may be held off for the ASCD. See the next
step.
10. If 24 volts is present at the UCB Y1 terminal and none of
the switches are open and the compressor is not locked
out, the UCB may have the compressor in an ASCD.
Check the LED for an indication of an ASCD cycle. The
ASCD should time out within 5 minutes. Press and release
the TEST button to reset all ASCDs.
11. If 24 volts is present at the UCB Y1 terminal and the
compressor is not out due to a protective switch trip, repeat
trip lock out, or ASCD, the economizer terminals of the
UCB may be improperly wired. Check for 24 volts at the Y1
“OUT” terminal of the UCB. If 24 volts is present, trace the
wiring from Y1 “OUT” for incorrect wiring. If 24 volts is not
present at the Y1 “OUT” terminal, the UCB must be
replaced.
12. For units without economizers: If 24 volts is present at the
Y1 OUT terminal, check for 24 volts at the Y1 “ECON”
terminal. If 24 volts is not present, check for loose wiring
from the Y1 “OUT” terminal to the Mate-N-Lock plug, the
jumper in the Mate-N-Lock plug, and in the wiring from the
Mate-N-Lock plug to the Y1 “ECON” terminal.
13. For units with economizers: If 24 volts is present at the Y1
“OUT” terminal, check for 24 volts at the Y1 “ECON”
terminal. If 24 volts is not present, check for loose wiring
Johnson Controls Unitary Products
from the Y1 “OUT” terminal to the Mate-N-Lock plug, a
poor connection between the UCB and economizer MateN-Lock plugs, loose wiring from the Mate-N-Lock plug to
the economizer, back to the Mate-N-Lock plug, and from
the Mate-N-Lock plug to the Y1 “ECON” terminal. If nothing
is found, the economizer actuator may have faulted and is
failing to return the 24-volt “call” to the Y1 “ECON” terminal
even though the economizer is not providing free cooling.
To test, disconnect the Mate-N-Locks and jumper between
the WHITE and YELLOW wires of the UCB’s Mate-N-Lock
plug. If the compressor energizes, there is a fault in the
economizer wiring or actuator.
14. The UCB can be programmed to lock out compressor
operation during free cooling and in low ambient
conditions. These options are not enabled by default. Local
distributors can test the UCB for this programming.
For units with factory installed economizers, the UCB is
programmed to lock out compressor operation when the
LAS set point is reached.
For units without factory installed or with field installed
economizers, the UCB allows compressor operation all the
time. This programming can be checked or changed by the
local distributor.
15. If none of the above correct the error, replace the UCB.
Unit Flash Codes
Various flash codes are utilized by the unit control board (UCB)
to aid in troubleshooting. Flash codes are distinguished by the
short on and off cycle used (approximately 200ms on and
200ms off). To show normal operation, the control boards
flashes a 1 second on, 1 second off “heartbeat” during normal
operation. This is to verify that the UCB is functioning correctly.
Do not confuse this with an error flash code. To prevent
confusion, a 1-flash, flash code is not used.
Current alarms or active restrictions are flashed on the UCB
LED.
• LAST ERROR - When this button is pressed and released
one time within five seconds, it flashes the last five flash
codes on the board’s LED. The most recent alarm is
shown first and the oldest alarm is shown last.
When pressed and released twice within a five second
span, the fault history is cleared.
• TEST RESET - When this button is pressed and released
one time within five seconds, any anti-short cycle delays
(ASCD) is by-passed for one cycle.
When this button is pressed twice within five seconds, any
active lockouts are reset.
• COMM SET UP - If the board is to be networked with
other units, this button is used to set the network address.
The first time the button is pressed within five seconds, it
scans the bus, then assigns itself the first available
address {starts at 2}. It then flashes that address one time.
Pressing the button two times within five seconds causes
the control to flash its address.
43
Pressing the button three times within five seconds forces
the control to reset its address to 1, which is the factory
default.
Fan On And Off Delays
1. These flash codes do not represent alarms.
Maintenance
Normal Maintenance
The fan ON and OFF delays can be field adjusted by pressing a
combination of buttons on the UCB.
• Electric Heat - Press and release the COMM SETUP and
LAST ERROR buttons at the same time. The control
flashes twice on the LED as the control writes a 0 second
ON and a 30 second OFF fan delay to the control’s
program memory.
Prior to any of the following maintenance procedures,
shut off all electric power to the unit to prevent personal
injury.
Filters
Inspect once a month. Replace disposable or clean permanent
type as necessary. DO NOT replace permanent type with
disposable. The dimensional size of the replacement filter must
be the same as the replaced filter.
