Comfort Alert Code 4.
CA1 Circuit 1 shutdown and retry after Anti-Short Cycle
Delay (ASCD). Maximum is 3 attempts.
Comfort Alert Code 5.
Circuit 1 shutdown and retry after ASCD.
CA1
Note: This alarm is sent by the Comfort Alert Module
only after the fault has been sensed for a minimum
of 4 hours.
Comfort Alert Code 6
CA1
Circuit 1 shutdown
Comfort Alert Code 7
CA1
Circuit 1 shutdown.
Comfort Alert Code 8
Run outdoor and indoor fans continuously for circuit
CA1 2 and change mode of operation to Unoccupied
Auto. This procedure prevents the Space
Temperature from reaching extreme values.
Comfort Alert Code 9. Shutdown and wait for voltage
CA1
to return to operational levels.
DDC
De-energize all relay outputs.
IFC IFC locks out for 1 hour
IFC flashes error code on LED, transmits the
IFC warning through the network, but otherwise
operates normally
If lost 17 times within single call for heat, locks out
IFC
for 1 hour. Otherwise retry ignition.
IFC Energizes inducer and main blower. Locks out
IFC
for 1 hour
If the low pressure switch trips 3 times within 120
minutes of operation during the same call for heating
DDC
operation, the control will lock out compressor and
outdoor fan operation. If the lock-out due to low
pressure occurs at an outdoor ambient temperature
below 5 °F, the control will automatically exit the
DDC
lock-out mode when the outdoor ambient
temperature rises above 5 °F. LPS is ignored during
defrost.
