2. 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 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. "AUTO RESTART FUNCTION" is OFF when the units are
shipped from the factory.
How to set "AUTO RESTART FUNCTION"
!
Turn off the main power for the unit.
@
Pull out the electronic control P.C. board, and change switch(SW2-1) on the indoor electronic control P.C. board
as follow figures.
Operation
!
If the main power (230V AC) has been cut, the operation settings remain.
@
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 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 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 cur-
rent by adding to the system that allows the units to start one by one.
