Experience the good'sleep mode

The good sleep mode is a special feature for the most comfortable sleep by automatically adjusting the temperature and humidity. This feature maintains optimal body temperature for maximum rest. In addition, it is able to reduce the energy consumption by 36% compared to the conventional cooling mode.

3 Stages of Good'Sleep Mode

Falling Asleep Stage (A) 

In this stage, the feature eases you into sleep by dropping the temperature. The temperature will decrease by 1-2° C from the set temperature. The duration of this stage is up to 1 hour.

Sound Sleep stage (B)

In this stage, your body temperature will be raised slightly. The air conditioner automatically raises the temperature 1-2° C from the set temperature. The duration is 2 to 7 hours and it can be adjusted independently by the user.

Wake up stage (C) 

This stage allows you to wake up with comfortable intermittent air and makes you feel refreshed. The temperature rises to 3° C to the set temperature and fluctuates within this range.
