    9. FUNCTION 9-1. Room Temperature Control Room temperature control is obtained by cycling the compressor ON and OFF under control of the room tem- perature sensor in the remote control unit. The room temperature (and other information) is transmitted every 3 minutes by the remote control unit to the controller in the indoor unit.

  • Page 34: Dry Operation

    9-2. 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.
