Operation

1If the main power has been cut, the operation settings remain.

2After the power is restored, the unit restarts automatically according to the memory.(However, it takes at least 3 minutes for the compressor to start running.)

NOTE

•The operation settings are memorized when 10 seconds have passed after the remote controller was operated with the remote controller.

•If main power is turned off or a power failure occurs while AUTO START/STOP timer is active, the timer setting is cancelled.

•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.

•When some air conditioners are connected to the same supply system, if they are operated before power failure, the starting current of all the compressors may flow simultaneously at restart.

Therefore, the special counter-measures are required to prevent the main voltage-drop or the rush of the starting current by adding to the system that allows the units to start one by one.
