8-2. Dry Operation (Dehumidification)
Dry operation uses the ability of the cooling cycle to remove moisture from the air, but by running at low level to
dehumidify without greatly reducing the room temperature. The air conditioner repeats the cycle of turning ON
and OFF automatically as shown in the chart below according to the room temperature.
