Air conditioners absorb heat in the room and transmits it to the outdoor unit, so that 
indoor ambient temperatures are decreased. Its cooling capacity will increase or 
decrease according to outdoor ambient temperature.
If the unit is running in COOL mode and in low ambient temperature, frost may be 
formed on the heat exchanger. When indoor heater exchanger temperature 
decreases below zero, the indoor unit microcomputer will stop the compressor 
running to protect the unit.
Air conditioners absorb heat from outdoors and transmit it to the indoor unit, 
increasing room temperature. Heating capacity will decrease in lower ambient 
temperatures.
When outdoor temperature is low but high humidity, frost may form on the outdoor 
unit during extended operation, affecting heating efficiency. The air conditioner 
operation ma y stop for 8-10mi ns during auto defrosting function.
During auto defrosting, the indoor indicator flashes and the outdoor unit may 
emit vapour. This is not a malfunction.
After defrosting has finished, the heating operation will recover automatically.
In "HEAT" mode, if in the following situations, the operation of indoor unit maybe 
delayed until the heat exchanger has achieved a certain temperature.
