To unlock the control panel, press the MENU SELECT and POOL/SPA buttons simultaneously.
DEFROST CYCLE
At air temperatures around 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.
