Why does the indoor fan run at a low speed and why is the green light flash during heating mode?
When air conditioner runs on anti- cold air mode, the green light flashing, and process see below: During heating mode, the temperature of room and evaporator is low, to avoid cold air blowing, the indoor unit runs in anti-cold air mode. When the evaporator temperature is below 15℃, the indoor motor doesn’t run, the outdoor unit runs. When the evaporator temperature is between 15℃ and 30℃, the indoor motor runs in breeze (lower than low speed), On anti-cold mode, outdoor unit keep running, so evaporator temperature rise rapidly. When the evaporator temperature rise to 26℃, the indoor motor runs in breeze, when rise to 30℃, the indoor motor runs in low speed, when rise to 34℃, the motor runs in medium speed, when the evaporator temperature is increased to 38℃,the indoor motor runs in the set speed.
