LOW NOISE MODE

The following reduces the operating sound of the outdoor unit from the normal sound.
The air conditioner is set to the "Low noise mode" when closing the contact input of a commercial
timer or ON/OFF switch to a connector on the outdoor control PC board.
* Performance may drop depending on the outside air temperature condition, etc.
