Trigger: While the compressor is running and unit mode is Cool, if saturated condenser temperature

is higher or equal to High Saturated Condenser Unload Value, the event is triggered.

Action Taken: Unload the compressor by decreasing the capacity by one step every 5 seconds until

the evaporator pressure rises above the High Condensing Pressure Unload set point.
