PRODUCT INTRODUCTION
Protect Functions
Protect functions can prolong the air conditioner' s service life and provide more comfortable airflow.
Delay-starting protection for the compressor
The compressor will restart working at least 3 minutes (5 minutes in heating mode) after 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.
Reset power or Auto restart (alternative)
Reset power: When there is a power suspension, air conditioner will automatically switch off. When the power is back,
the unit will automatically reset power. For energy saving if there is no person in the room, air conditioner will stay in
PAUSE status. User needs to turn on Air conditioner by remote controller.
Auto restart: The unit memories the operation mode, air flow setting, temperature setting etc., so that should there be a
power failure when the unit is in operation, it will automatically return the same operating conditions when the power is
restored.
Cooling overload working (optional)
In cooling operation, if the temperature of outdoor heat exchanger is too high, indoor fan speed will be adjusted to a
lower gear automatically and compressor may be stopped.
Drip proof (optional)
In cooling and dehumidification operation, louver blades can change the position automatically to prevent from dripping.
