About night quiet mode

The night quiet mode function reduces operating noise of the outdoor unit at nighttime. This function is useful if the user is

worried about the effects of the operating noise on the neighbors.

However, if night quiet mode is running, cooling capacity will be saved.

Setting procedure

Turn the night quiet mode switch (SW6-1) to on.
