Removal of Unit from Common Venting System
When an existing furnace is removed from a common
ventingsystemservingotherappliances,the venting system
is likely to be too large to properly vent the remaining
attachedappliances.Thefollowingtestshouldbeconducted
with each appliance while the other appliances connected
to the common venting system are not in operation.
1. Seal any unused openings in the common venting
system.
2. Visually inspect the venting system for proper size and
horizontal pitch and determine there is no blockage or
restriction, leakage, corrosion, or other deficiencies
which could cause an unsafe condition.
3. Insofar as is practical, close all building doors and
windows between the space in which the appliances
remaining connected to the common venting system
are located and other spaces in the building. Turn on
clothes dryers and any appliance not connected to the
common venting system. Turn on exhaust fans, such
as range hoods and bathroom exhausts, so they will
operate at maximum speed. Do not operate a summer
exhaust fan. Close fireplace dampers.
4. Following the lighting instructions, place the unit being
inspected in operation. Adjust the thermostat so the
appliance will operate continuously.
5. Test for spillage at the draft control relief opening after
5 minutes of main burner operation. Use the flame of a
match or candle.
6. Follow the preceding steps for each appliance
connected to the common venting system.
7. After it has been determined that each appliance
remaining connected to the common venting system
properly vents when tested as outlined above, return
doors, windows, exhaust fans, fireplace dampers,
and any other fuel burning appliance to their previous
condition of use.
8. If improper venting is observed during any of the
above tests, the common venting system must be
corrected. See National Fuel Gas Code,ANSI Z223.1
(latest edition) or CAN/CGA B149.1 & .2 Canadian
Installation Codes to correct improper operation of
common venting system.

Cooling
When the thermostat is in the cooling mode, the O circuit is
poweredwhich energizes thereversing valve. Upon cooling
demand, the thermostat closes circuit R and Y. Closing R
and Y closes the unit contactor, starting the compressor
and outdoor fan. Closing R to Y also brings on the indoor
blower at the same time. Upon satisfying cooling demand,
the thermostat will open the above circuits and open the
main contactor, stopping the compressor and outdoor fan.
The blower will continue to operate for 60 seconds which
improves system efficiency.
NOTE: There is no blower off delay when there is only a
cell for G (fan only).
Heating
Upon first stage heating demand, the thermostat closes
circuit R to Y, which closes the unit contactor, starting the
compressor and outdoor fan. The reversing valve is not
energizedintheheatingmode.Thethermostatautomatically
bringsontheindoorblower at the selected heatpumpspeed
at the same time. Upon satisfying the heating demand,
the thermostat opens the above circuits and stops the
compressor and outdoor fan. The blower will continue
running for an additional 60 seconds.
Units with Electric Heater (If accessory is field installed)
Ifduring a first stage heating demand the thermostat closes
theRtoWcircuit calling for a secondstageheatingdemand,
theelectric heater is energized. The compressor continues
to operate in heating mode. At the same time the indoor
blower is energized on the selected heting speed. If the
second stage heat demand is satisfied, the electric heat
stages off and indoor blower returns to the selected heat
pump speed.
Sequence of Operation
RCE Models
Cooling
Whenthethermostatcalls for cooling, Risclosed to G andY
(seewiring diagram). This actioncompletes the low voltage
control circuit, energizing the compressor, condenser fan
motor and blower motor.
Unit compressors have internal protection. If there is an
abnormalrise in the compressor temperature, the protector
will open and the compressor will stop.
Blower Delay-Cooling
In cooling mode, the circulating air blower operation is
delayed for five (5) seconds after the compressor starts.
The blower continues to operate for 60 seconds after the
compressor is de-eneregized. The feature is a function of
the blower motor itself and cannot be changed.
NOTE: There is no blower off delay when there is only a
call for G (fan only).
Electric Heat (If accessory is field installed)
When the thermostat calls for heat, R is closed to W (see
wiring diagram). This action energizes the blower motor
at the selected heat speed and also energizes the electric
heat elements through the sequencer (located on the field
installed electric heater panel). Upon satisfying heating
demand, the thermostat opens the W circuit, de-energizing
theelectricheater. The blower motorwillcontinuetooperate
for an additional 2 minutes before stopping.

Compressor Delay
The defrost board has a field-selectable function to reduce
occasionalsounds that mayoccur while the unit is cycling in
and out of the defrost mode. The compressor will be cycled
offfor30secondsgoinginand out ofthedefrostmode when
thecompressordelayjumperis installed. For optimal energy
performance, remove the delay jumper.
NOTE: The 30-second “off” cycle is not functional when
jumpering the TEST pins.
Time Delay
The timed-off delay is 5 minutes long. The delay helps to
protectthe compressor fromshort cycling incase the power
to the unit is interrupted or a pressure switch opens. The
delayis bypassed by placing thetimer select jumper across
the TEST pins for 0.5 seconds.
Pressure Switch Circuit
Highandlowpressureswitches are connected to thedefrost
control board on heat pump models (see Figure 8 on page
8). Air conditioning models have a high pressure switch
installed in line with compressor contactor coil.
NOTE: If both first and second stage heating demand
are satisfied at the same time or if the unit is operating in
emergency heat mode and the demand is satisfied, the
heat pump and heaters are de-energized while the blower
will continue to operate for an additional 2 minutes before
stopping.
Defrost System
The defrost system includes two components: the defrost
thermostat and the defrost control.
Defrost Thermostat
The defrost thermostat is located on the liquid line between the
check/expansion valve and the distributor. When the defrost
thermostat senses 42°F or cooler, the thermostat contacts close
and send a signal to the defrost control board to start the defrost
Ɵming. It also terminates defrost when the liquid line warms up
to 70°F.
Defrost Control
The defrost control board includes the combined funcƟons of
Ɵme/temperature defrost control, defrost relay, diagnosƟc LEDs
and terminal strip for field wiring connecƟons (see Figure 8).
The control provides automaƟc switching from normal heaƟng
operaƟon to defrost mode and back. During the compressor
cycle (call for defrost), the control accumulates compressor run
Ɵme at 30, 60, 90 minute field-adjustable intervals. If the defrost
thermostat is closed when the selected compressor run Ɵme
interval ends, the defrost relay is energized and the defrost begins.
Defrost Control Timing Pins
Each timing pin selection provides a different accumulated
compressorruntimeperiodduringone thermostat run cycle.
Thistimeperiodmustoccurbeforeadefrostcycleisinitiated.
Thedefrostintervalcanbeadjustedto30(T1), 90 (T2), or 90
(T3) minutes. The defrost timing jumper is factory installed
toprovide a 90-minute defrost interval. If the timing selector
jumper is not in place, the control defaults to a 90-minute
defrost interval. The maximum defrost period is 14 minutes
and cannot be adjusted. For optimal system performance,
move the jumper to the 60 minute defrost interval.
A test option is provided for troubleshooting. The test mode
may be started any time the unit is in the heating mode and
the defrost thermostat is closed or jumpered. If the jumper
is in the TEST position at power up, the control will ignore
the test pins. When the jumper is placed across the TEST
pins for 2 seconds, the control will enter the defrost mode. If
the jumper is removed before an additional 5-second period
has elapsed (7 seconds total), the unit will remain in defrost
mode until the defrost thermostat opens or 14 minutes have
passed. If the jumper is not removed until after the additional
5-second period has elapsed, the defrost will terminate and
the test option will not function again until the jumper is
removed and reapplied.

During a single demand cycle, the defrost control will
lock out the unit after the fifth time that the circuit is
interrupted by any pressure switch wired to the control
board. In addition, the diagnostic LEDs will indicate a
locked-out pressure switch after the fifth occurrence of
an open pressure switch (see Table 3).
The unit will remain locked out until power to the board
is interrupted, then re-established, or until the jumper
is applied to the TEST pins for 0.5 seconds.
NOTE: Thedefrost control board ignores input from the low
pressure switch terminals as follows:
• During the TEST mode
• During the defrost cycle
• During the 90-second start-up period
• For the first 90 seconds each time the reversing
valve switches heat/cool modes
If the TEST pins are jumpered and the 5-minute delay
is being bypassed, the LO PS terminal signal is not
ignored during the 90-second start-up period.
Diagnostic LEDs
The defrost board uses two LEDs for diagnostics. The
LEDs flash a specific sequence according to the condition
as shown in Table 3.
System Performance (RCE, RHP Models)
This equipment is a self contained, factory optimized
refrigerant system, and should require no adjustments
when properly installed. If however unit performance is
questioned, perform the following checks.
Insure unit is installed per manufacturer’s instructions and
that line voltage and air flows are correct. Refer to Table 4
for proper superheat values. Check super heat settings by
measuringpressureatthesuction line service port. ForTXV
systems, measure pressure at the liquid service port. Take
line temperature within 2 inches of service port connection
to its main tube. If unit superheat/subcooling varies by
more than table allowance, check internal seals, service
panels and duct work for air leaks, as well as restrictions
and blower speed settings. If unit performance remains
questionable, remove charge, evacuate to 500 Microns,
and weigh in refrigerant to name plate charge. It is critical
that the exact charge is re-installed. Failure to comply will
compromisesystemperformance. Ifunit performance is still
questionable, check for refrigerant related problems such
as,blocked coil or circuits, malfunctioningmetering devices
or other system components.

ment, including operation of electrical equipment at voltages other than the range specified on the unit nameplate (includes damages caused by brownouts), or reverse rotation of compressors or motors due to improper phasing.

The manufacturer makes no express warranties other than the warranty
specified above. All implied warranties, including the implied warranty of merchantability and fitness for a particular purpose, are excluded to the extent legally permissible. Should such exclusion or limitation of the warranty be unenforceable, such implied warranties are in any event limited to to a period of one (1) year. Liability for incidental and conse- quential damages is excluded. Some states do not allow limitations on the duration of an implied warranty or the exclusion or limitation of inci- dental or consequential damages, so the limitations or exclusions may not apply to you.
The manufacturer will not pay electricity or fuel costs, or increases in
electricity or fuel costs, for any reason whatsoever, including additional
or unusual use of supplemental electric heat. This warranty does not cover lodging expenses.
The manufacturer shall not be liable for any default or delay in perfor-
mance under this warranty caused by any contingency beyond its con- trol.
This warranty gives you specific legal rights, and you may also have other
rights which vary from state to state.
