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 4°F (2°C) away from the set tem-
perature for more than 15 minutes.
Note:
Auto Mode is not recommended if this indoor unit is connected to a MXZ type out-
door 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

Note:
Do not operate COOL mode at very low outside temperatures (less than 14°F
[-10°C]). Water condensed in the unit may drip and wet or damage furniture, etc.
DRY mode
Dehumidify your room. The room may be cooled slightly.
Temperature cannot be set during DRY mode.
