CAUTION
Be careful not to make mis-wiring.
Firmly tighten the terminal screws to prevent them from loosening.
After tightening, pull the wires lightly to confirm that they do not move.
If the connecting wire is incorrectly connected to the terminal block, the unit does
not operate normally.
If an earth is incorrect, it may cause an electric shock.
4-5 AUTO RESTART FUNCTION
These models are equipped with an auto restart function. If you do not want to use this
function, please consult the service representative because the setting of the unit needs
to be changed.
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 “AUTO”
mode before power failure, the operation mode (COOL, DRY or HEAT) is not stored in
the memory. When the main power is turned on, the unit decides the operation mode
by the initial room temperature at restart and starts operation again.
Operation
1 If the main power (230V AC) has been cut, the operation settings remain.
2 When three minutes have passed after power was restored, the unit will restart
automatically according to the memory.
Notes:
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. As these models are equipped with the
auto restart function, the air conditioner should start operating at the same time that
a power has restored.
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.
