 AUTO mode (Auto change over)

The unit selects the operation mode according to the difference between the 

room temperature and the set temperature. During AUTO mode, the unit 

changes mode (COOL↔HEAT) when the room temperature is 2°C away 

from the set temperature for more than 15 minutes.

Note: 

Auto Mode is not recommended if this indoor unit is connected to a MXZ 

type outdoor unit. When several indoor units are operated simultaneously, 

the unit may not be able to switch operation mode between COOL and 

HEAT. In this case, the indoor unit becomes standby mode (Refer to table 

of Operation indicator lamp).

 COOL mode

Enjoy cool air at your desired temperature. 

Note: 

Do not operate COOL mode at very low outside temperatures (less than 

-10°C). Water condensed in the unit may drip and wet or damage furni-

ture, etc.

  DRY mode

Dehumidify your room. The room may be cooled slightly. 

Temperature cannot be set during DRY mode.

 HEAT mode

Enjoy warm air at your desired temperature.

  FAN mode

Circulate the air in your room.

Each press raises or lowers the temperature by 1°C.

 

Press 

 to stop the operation.

Auto restart function

If a power failure occurs or the main power is turned off during operation, “Auto 

restart function” automatically starts operation in the same mode as the one 

set with the remote controller just before the shutoff of the main power. When 

timer is set, timer setting is cancelled and the unit starts operation when power 

is resumed.

If you do not want to use this function, please consult the service repre-

sentative because the setting of the unit needs to be changed.
