OPERATION
Fan The fan will run constantly except when a defrost is initiated, or when the evaporator temp is above 35oF. When in defrost mode the fan is off until the end of the defrost and the 2 minute drip time has passed. There is 2 minutes delay after a defrost before the fan comes on. The difference of the evaporator and room temperature of more than 9oF will override the fan delay. FAN LED indicator is flashing during 2 minutes drip period.
Defrost The control uses time defrosts with four defrost per day for oil return safety. The defrost timer begins counting on power up. For example, if a defrost is desired at 12 am, 6 am, 12m, and 6 pm then power up the unit at any of those four times.
