  • Page 26: Function

    10. FUNCTION 10-1. Room Temperature Control Cooling 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 27 Heating 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 28: Dry Operation

    10-2. 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.

  • Page 29: Freeze Prevention

    10-3. Freeze Prevention (Cooling) This function prevents freezing of the indoor heat exchange coil. When the compressor has been running for 10 minutes or more and the temperature of the indoor heat exchange coil falls below –1°C, the control circuit stops the compressor for at least 6 minutes. The compressor does not start again until the temperature rises above 8°C or 6 minutes has elapsed.

  • Page 30: Cold Draft Prevention

    10-5. Cold Draft Prevention (Heating) This function controls indoor fan speed so a strong draft of cold air will not blow out before the indoor heat exchange coil have sufficiently warmed up.
