AUTO RESTART FUNCTION

• These models are equipped with an auto restart function. If you do not want to use this function, please
consult the service representative because the setting of the unit needs to be changed.
• When the indoor unit is controlled with the remote controller, the operation mode, the set temperature, and
the fan speed are memorized by the indoor electronic control P.C. board. The auto restart function sets to
work the moment the power has restored after power failure, then, the unit will restart automatically. If the unit
is operated in "AUTO" mode before power failure, the operation mode (COOL, DRY or HEAT) is not stored in
the memory. When the main power is turned on, the unit decides the operation mode by the initial room
temperature at restart and starts operation again.
Operation
1 If the main power has been cut, the operation settings remain.
2 When three minutes have passed after power was restored, the unit will restart automatically according to
the memory.
Notes:
• The operation settings are memorized when 10 seconds have passed after the remote controller was oper-
ated.
• If the main power is turned off or a power failure occurs while AUTO START/STOP timer is active, the timer
setting is cancelled. As these models are equipped with an auto restart function, the air conditioner starts
operating with timer cancelled at the same time that power is restored.
• If the unit has been off with the remote controller before power failure, the auto restart function does not work
as the power button of the remote controller is off.
• To prevent breaker off due to the rush of starting current, systematize other home appliances not to turn on
at the same time.
