2-5 Auto restart function
When the air conditioner is controlled by the remote
controller, indoor unit electrical board will memorize
operation mode, set temperature and fan speed. If there
is a power-off during operation, Auto restart function is
enabled to restart the air conditioner after recovery of
power supply. If the air conditioner operates in the mode
of "I FEEL CONTROL" before power-off, the mode will be
memorized. In "I FEEL CONTROL" mode, air conditioner
operation depends on indoor temperature at restarting.
How to set Auto Restart Function
Remove the front panel.
①
②
Remove the screws of electrical cover. Remove the electrical cover.
Remove the connector of blade motor from CN151 and CN152;
③
Remove the wires of blade motor inside the electrical terminal block;
Remove the temperature sensor connector from CN112;
Remove the dynamic ground temperature sensor connector from
CN110.
④
Pull out the electrical control board and disconnect the resistor JR07
on it (near CN111).
Operation
①The operation setting is still reserved at power-off.
②The air conditioner will restart automatically according to the
memory after 3 minutes of power supply recovery.
Note:
•The operation setting will be reserved after 10 seconds of
remote controller operation.
A
•When the Auto ON/OFF timer is activated, the timer setting will
be cancelled in the event of power-off or power failure. As Auto
Restart function is equipped inside these models, once the
power is recovered, the air conditioner will start to operate three
minutes later.
•If the air conditioner is turned off by the remote controller before
power-off, Auto Restart function will be disabled due to power
button's OFF status in the remote controller.
•In order to prevent impulse current from affecting the power
supply, please arrange a sequence to start other household
appliances to avoid simultaneous power-on.
