How to set the remote controller exclusively for particular indoor unit
After you turn the breaker ON, the first remote controller that sends the signal to the indoor unit will be regarded as the
remote controller for the indoor unit.
The indoor unit will only accepts the signal from the remote controller that has been assigned to the indoor unit once they
are set.
The setting will be cancelled if the breaker has turned off, or the power supply has shut down.
Please conduct the above setting once again after the power has restored.
9-5. 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. However 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.
How to set "AUTO RESTART FUNCTION"
1
Turn off the main power for the unit.
2
Pull out the indoor electronic control P.C. board and the display P.C.board. (Refer to page 51.)
3
Cut the RESISTOR JR07 on the indoor electronic control P.C.board.(Refer to page 49.)
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 remote controller was operated.
•
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 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.
