Testing
FIELD TEST MODE
If the two 'TEST" quick connect terminals are
connected, there will be no random start delay,
no anti-short cycle delay, and no power to delay
present. The normal fan, reversing valve, and
compressor on delays of two, four, and six
seconds will still be present, as well as the four
second reversing off delay.
FACTORY TEST MODE
The factory mode is entered by applying the
correct combination of inputs to the control at
power up. The factory test mode operates the
control by associating
control outputs with inputs. The factory test
mode is automatically canceled after 30 seconds
after control power up, and may not be run again
until power is removed from the control.
Factory Test Mode Initiation: The control
checks the control inputs during the first 1.0
seconds after power up, looking for the factory
speedup input combination. To initiate the
factory lest mode, at some point during the first
1.0 seconds after power up, the high pressure
switch input must be active, the "SENSOR" input
must have 470 kΩ connected, the two "TEST"
quick-connect terminals connected, voltage
source must be between 22 to 29 VAC, and all
of the other inputs must be inactive.
Factory Test Mode Operation: While in the
factory test mode, the following combinations of
inputs will result in the operation of the
corresponding output conditions:
LED stays active.
“O” thermostat input active and night
setback input inactive - Reversing valve
output active.
“G” thermostat input active and emergency
shutdown input inactive - Fan output active.
“Y” thermostat input active and high
pressure switch input active - Compressor
output active.
Thermostat night setback input active and
override input inactive - Alarm output active.
