Low=Pressure
Switch
-- A low-pressure
switch is factory-installed in select models only.
If provided, this switch is located in the suction
line internal to the outdoor unit. The switch is
designed to protect the compressor from a loss
of charge. Under normal conditions, the switch
is closed. If the suction pressure falls below 5
psig, then the switch will open and de-energize
the outdoor unit. The switch will close again
once the suction pressure increases above 20
psig. Please note that the switch interrupts the
thermostat inputs to the unit. Thus, when the
switch opens and then closes, there will be a 5
minute short cycling delay before the outdoor
unit will energize.
Comfort Alert TM Diagnostics
(Select Models)
-- The Comfort Alert TM diagnostics module is
a breakthrough innovation for troubleshooting
heat pump and air conditioning system failures.
The module installs easily in the electric box of
the outdoor unit near the compressor contactot. By monitoring and analyzing data from the
Copeland Scroll compressor® and the thermostat demand, the module can accurately detect
the cause of electrical and system related failures
without any sensors. A flashing LED indicator
communicates the ALERT code and guides the
service technician more quickly and accurately
to the root cause of a problem.
The scroll compressor's run (R), common (C) and
start (S) wires are routed through the holes in the
Comfort Alert TM module marked "R,'"C" and "S."
The common (C) wire need not be routed through
the module for it to operate properly.
24 VAC Power Wiring -- The Comfort Alert TM
module requires a constant nominal 24 VAC
power supply.The wiring to the module's R and
C terminals must be directly from the indoor unit
or thermostat.

Table 2. Module Wiring Troubleshooting
To set the cycle timer, place the timing pin on
the defrost control board to the desired time
interval post.
Note: All units are shipped from the factory with
the default time setting of 30 minutes. Maximum
heating performance can be achieved by setting
the time to 90 minutes.
Defrost Test Procedure
1.
2.
Terminals"R'-'C" must have 18-30v present
between them in order for time delay and
defrost sequences to be initiated.
With compressor running in heat mode,
first jump the "T2"-'DFT" test pins. This
will indicate to board that defrost T-stat is
closed. Defrost T-stat closes at 32 °, opens
at 68 ° .
3.
4.
Next jump the "Test" pin to "C" on terminal
strip.This will initiate defrost test in 5, 10 or
15 seconds (This is determined by 30, 60
or 90 minutes defrost pin settings). Factory
setting will be 30 minutes.
When the reversing valve shifts to the
defrost mode, quickly remove jumper from
"Test'-'C'.
If the jumper is not removed
within a 5 second period, the defrost test
will terminate. Unit will continue to stay in
defrost mode Until :
A)
B)
C)
Board recognizes that defrost
sensor has reached 68 ° and
opened or
"T2"-'DFT'jumper
is removed or
10 minutes have elapsed (board
override)
If the above steps will not initiate a defrost, replace
the defrost board.
Anti Short Cycle Timer Test
The 5 minute time delay featu re can be bypassed
or shortened to 1 second by jumping the "Test"
to "C" terminal.
Note: If jumper is left on the "Test" to "common"
pins permanently, the defrost cycle will become
inoperable.
