UNIT OPERATION
This control board contains a 3.5 minute short cycle protector. A 3.5 minute delay will occur between
Compressor off/on cycles. To bypass delay, short forced defrost pins for 1 second then release.
However, there is an additional 2.5 minutes delay upon expiration of the 3.5 minute short cycle delay to
ensure the high and low side pressures are equalized. This is important for long term rotary compressor
reliability. It is a delay that cannot and must not be bypassed. The internal crankcase heater is energized
during off cycle as needed.
