mode
D804 D805
You can set DIP switches to select the noise level in Night operation (Sound reduction) mode(*1)(*2).
1. Make sure of the color (green or black) of the DIP switches (SW01) on the PC board.
2. Referring to the table below, set the DIP switches for the desired noise level.
*1 Night Operation limits the outdoor fan and compressor revolution speed, leading to a decrease in capacity.
*2 Depending on the remote controller to be connected, the same setting can be made from the remote controller.
For details, refer to the Installation manual of the remote controller, If different level settings are set from both the
Application Control Kit and the remote controller the quieter setting is prioritized.
