AUTO RESTART FUNCTION
When the indoor unit is controlled with the remote controller, the operation mode, 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 "I FEEL CONTROL" mode before power failure, the operation is not memorized. In
"I FEEL CONTROL" mode, the operation is decided by the initial room temperature at (re)start.
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 this model is equipped with the auto restart function, the air conditioner should start
operating at the same time that a power has 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 appliance not to turn on at
the same time.
