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 about 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 furniture, etc.
DRY mode
Dehumidify your room. The room may be cooled slightly.
Temperature cannot be set during DRY mode.

ELECTING OPERATION MODES
Note:
Multi system operation
Two or more indoor units can be operated by one outdoor unit. When several
indoor units are operated simultaneously, cooling and heating operations can-
not be done at the same time. When COOL is selected with one unit and HEAT
with another or vice versa, the unit selected last goes into standby mode.
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.
