How to release "AUTO RESTART FUNCTION"
1
Turn off the main power for the unit.
2
Solder the Jumper wire to JR07 on the indoor electronic control P.C. board. (Refer to 9-7.)
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.
