Night-time low noise operation can be set in mode 2. There are two methods to activate
night-time low noise operation of the outdoor unit system.
The first method is to enable an automatic night-time low noise operation by field
setting. The unit will operate at the selected low noise level during the selected time
frames.
The second method is to enable night-time low noise operation based on an external
input. For this operation an optional accessory is required.
