Default setting value
- 4Way Cassette, Mini 4Way Cassette: 5 °C
- Other indoor units: 2 °C
(*5)
This function can be applied to 4 Way Cassette and Mini 4 Way Cassette only. If the air conditioner operates the heating
mode immediately after finishing the cooling mode, the condensated water in the drain pan becomes water vapor by
the heat of the indoor unit heat exchanger. Since the water vapor might be condensed on the indoor unit, which may
fall into a living space, use this function to get rid of the water vapor out of the indoor unit by operating the fan (for
maximum 20 minutes) even when the indoor unit is turned off after cooling mode is turned to heating mode .
