Defrost thermistor
Pre-heat control ON condition
(1) Compressor is not operating. (However, pre-heat control is still OFF for 30 minutes after compressor is stopped,
regardless of the outside temperature.)
(2) Defrost thermistor reads 20°C or below.
Defrost thermistor monitor hourly, and when defrost thermistor reads 20°C or below, pre-heat control is turned ON.
When pre-heat control is turned ON, compressor is energized about 50 W (40-60 W). (Compressor and fan are not operated.)
