DEFROST CYCLE
At air temperatures below 50° F, the heat pump may enter a defrost cycle. The defrost cycle is
initiated when a sensor on the evaporator detects that the refrigerant temperature has fallen below the
defrost set point. At this time, the heat pump compressor will stop. The heat pump evaporator fan will
continue to run, and will draw air over the evaporator fins for about 15 minutes. If, at the end of the
15 minutes, the temperature sensor detects a temperature above 44° F, the compressor will restart.
Otherwise the unit will shut down.
Because a heat pump's efficiency decreases as air temperature decreases, it is preferable to operate
the heat pump during the warmest time of day. As a rule, the unit should not be operated during the
coolest time of day, or when the air temperature falls below 45° F.
