AUTO RESTART FUNCTION
When the indoor unit is controlled by the remote controller; the operation mode, set temperature, and the fan speed are
memorized by the indoor electronic control P.C. board. After power failure, the unit operates automatically when power is
restored. In case of unit 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 temperature. Refer to page 28.
How to set AUTO RESTART FUNCTION
Cut the jumper wire JR84
Operation
a) If main power
(ACI 15V) is cut, the operation settings remain.
b)
When power is restored, the unit restarts in previous mode
3
minutes later without remote controller.
c) Even if power is cut for about 0.5 seconds, auto restart works.
Note
a) If main power is cut while AUTO START/STOP timer is set, the timer setting is cancelled when auto restart function
works.
b) If the unit was off by the remote controller before power failure, auto restart function does not work as the power button
of the remote controller is off.
