10-4. AUTO RESTART FUNCTION
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 “I FEEL CON-
TROL.” mode before power failure, the operation is not memorized. In “I FEEL CONTROL.” mode, the operation is decid-
ed by the initial room temperature at (re)start.
How to set “AUTO RESTART FUNCTION”
1
Turn off the main power for the unit.
2
Remove the indoor electronic control P.C. board and the display P.C.board.(See page 57.)
3
Pull the indoor electronic control P.C. board forward and cut the RESISTOR JR07 on it.

Operation
1
If the main power (220-240V AC) has been cut, the operation settings remain.
2
After 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 indoor unit was operated with the remote
controller.
•
If the 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.
