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 4°F
(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
14°F [-10°C]). Water condensed in the unit may drip and wet or damage
furniture, etc.

control does not work, and fan speed is set to High.
• In the emergency heating operation, the fan speed gradually
rises to blow out warm air.
• In the emergency cooling operation, the horizontal vanes' po-
sition will be reset in about a minute, then the operation will
start.
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.
