Basic function
Basic operation is an operation mode that can be selected by pressing the Mode button.
Auto(2-Step Cooling or Heat)
In Auto mode, the air conditioner will automatically set the temperature and fan speed depending on the room
temperature detected by the room temperature sensor.
t 2-Step Cooling mode sets the air conditioner to operate in Fast + Cool mode when set temperature is lower than indoor
temperature, and then the air conditioner will automatically operate in Dry mode when indoor temperature reaches set
temperature.
Cool
In Cool mode, the air conditioner will cool your room. You can adjust the temperature and the fan speed to feel cooler in hot
season.
t If current outside temperature is much higher than the selected indoor temperature, it may take time to bring the inner
temperature to the desired coolness.
t Quiet mode makes the unit quieter during the operation of the indoor unit in the Cool mode.
Dry
The air conditioner in Dry mode acts like a dehumidier by removing moisture from the indoor air.
Dry mode makes the air feel refreshing in a humid climate.
To activate the Dry mode, set temperature on the remote controller should be lower than indoor room temperature.
Fan
Fan mode can be selected to circulate your room. Fan mode will be helpful to refresh the stale air in your room.
Heat
The air conditioner heats as well as cools. Warm your room with this versatile appliance in the cold of winter.
t Fan may not operate for about 3~5 minutes at the beginning to prevent any cold blasts while the air conditioner is
warming up.
