Press the SLEEP button when you are ready to go to sleep. When in COOL mode, the unit will increase the temperature by 1°C (2°F) after 1 hour, and will increase an additional 1°C (2°F) after another hour.
When in HEAT mode, the unit will decrease the temperature by 1°C (2°F) after 1 hour, and will decrease an additional 1°C (2°F)after another hour.
The sleep feature will stop after 8 hours and the system will keep running with final situation.

Active Clean function (Multi-Zone Systems models do not have this function)

The Active Clean Technology washes away
dust when it adheres to the heat exchanger by automatically freezing and then rapidly thawing the frost. A “pi-pi” sound will be heard.
The Active clean operation is used to produce more condensed water to improve the cleaning effect, and the cold air will blow out. After cleaning, the internal wind wheel then keeps operating with hot air to blow-dry the evaporator, thus keeping the inside clean.

• When this function is turned on, the indoor unit display window appears “CL ” , after 20 to 130 minutes, the unit will turn off automatically and cancel Active Clean function.
