NOTE:

The operation settings are memorized when 10 seconds have passed after the indoor unit 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 works 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.

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.
