Specifies how long the compressor remains powered off when the controller is powered on.
Compressor Minimum On Time
Specifies the minimum time that the compressor is powered on regardless of whether the control temperature decreases to less than the Cut-Out setpoint.
Specify how long the compressor remains powered on before normal controller programming powers it off.
NOTE: The adjustment knob off position immediately powers off the compressor.
Compressor Minimum Off Time
Specifies how long the compressor remains powered off before the controller powers it on. This timer must expire and the temperature must be greater than
the Cut-In setpoint for the controller to power on the compressor.
