8.4.14 Louver Position Memory Function
When starting the unit again after shutting down, its louver will restore to the angle originally set by the
user, but the precondition is that the angle must be within the allowable range, if it exceeds, it will
memorize the maximum angle of the louver. During operation, if the power fails or the end user shuts
down the unit in the turbo mode, the louver will restore to the default angle.
8.4.15 INTELLIGENT EYE(optional)
With the built-in infrared sensor, the indoor unit detects human movement. The AC will turn off if you
leave the room for 30 minutes and turn on automatically when you come back, which helps saving
more energy.
8.4.16 Silence operation(optional)
Press the “silence” button on remote controller to initiate SILENCE function. When the Silence function
is activated, the compressor running frequency will keep lower than F2 and the indoor unit will bring
faint breeze, which will reduce the noise to the lowest level and create a quiet and comfortable room
for you.

The PCB will detect the voltage of power supply and adjust the compressor running frequency to
protect the system.
In the first 10 seconds after power on, this protection is inactive.
When this protection happens, it will last 3 minutes and then the PCB will detect the power supply
voltage again.
