Automatic Defrost
At low room temperatures, frost may build up at the evaporator during
operation. The unit will automatically start defrosting and the
POWER
LED will
blink. The defrost control sequence is as follows:
A. When the unit operates in the cooling operation or drying operation, and
the ambient temperature sensor senses the evaporator coil temperature
is below -1°C, then the compressor will stop operating for 10 minutes or
until the coil temperature reaches 7°C, then the unit will restart the cooling
operating mode.
B. When the unit operates in the heating operation or drying operation, and
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 has been operating
for 20 minutes, the unit will start defrosting for 5 minutes and the power
indicator will blink.
Overload Protection
In the event of power loss, to protect the compressor there is a 3-minute delay
before the compressor restarts.
