At low room temperatures, frost may buildup at the evaporator during
operation. The unit will automatically start defrosting and the POWER
LED blinking. The defrost control sequence is as follows:
A. When the unit operates in the cooling operation, drying operation, the
ambient temperature sensor senses the evaporator coil temperature is
below -1°C, after the compressor will stop operating for 10 minutes or
the coil temperature up to 7°C, the unit restart to cool operating mode.
B. When the unit operates in the heating operation, drying operation, once the
coil temperature sensor senses the temperature of the evaporator is below
40°C and the differential temperature between coil temperature and room
temperature is below 19°C after the compressor operation for 20 minutes,
the unit start defrosting for 5 minutes and the power indicator blinking.
