To Dehumidify with A/C(optional on DX)
Because an air conditioner dehumidities as it works, you can use it
in cool or cold weather to help defog the windows. Just switch the
fan on, push the A/C button on, select the desired function and
adjust the temperature lever/control dial to a comfortable setting.
NOTE:
This setting is desirable for most operating conditions in ambient
temperatures above approximately 32°F (0°C).
