Defrost Cycle
The UltraTemp
®
Heat Pump may enter a defrost cycle
if air temperatures are around 50° F (10° C).
The defrost cycle initiates when the evaporator sensor
detects refrigerant temperature below the defrost set
point. At this time, the heat pump compressor stops.
The heat pump evaporator fan will continue to run,
and will draw air over the evaporator fins for about 15
minutes.
If the temperature sensor detects a temperature above
44° F (7° C), the compressor will restart after the 15
minutes. If not, the unit will shut down.
The efficiency of a heat pump decreases as air
temperature decreases. For maximum efficiency,
operate the heat pump during the warmest time of day.
