being turned off to keep the pressure balance of the cooling system.
Remarks: There will be 1 minute for the compressor to work after the unit is electrified for
the first time.
Freeze-prevention
To prevent indoor heat exchanger freezing in cooling and dehumidification operation,
compressor or outdoor fan may stop running; indoor fan speed will be adjusted to a
higher gear automatically.
Dry for enzyme-prevention (optional)
Indoor fan motor will go on running for 3 minutes at low fan speed when turned off in cooling
mode in order to keep dry condition inside the unit.

there is no person in the room, air conditioner will stay in PAUSE status. User needs to
turn on Air conditioner by remote controller.

automatically return the same operating conditions when the power is restored.

speed will be adjusted to a lower gear automatically and compressor may be stopped.
