  • Page 30: Function

    8. FUNCTION 8-1. Room Temperature Control Cooling Room temperature control is obtained by cycling the compressor ON and OFF under control of the room temperature sensor in the remote control unit. The room temperature (and other information) is transmitted every 5 minutes by the remote control unit to the controller in the indoor unit.
  • Page 31 Heating Room temperature control is obtained by cycling the compressor ON and OFF under control of the room temperature sensor in the remote control unit. The room temperature (and other information) is transmitted every 5 minutes by the remote control unit to the controller in the indoor unit.

  • Page 32: Dry Operation

    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.

  • Page 33: Freeze Prevention

    8-4. Freeze Prevention (Cooling and Dry) This function prevents freezing of the indoor heat exchange coil. When the compressor has been running for 6 minutes or more and the temperature of the indoor heat exchange coil falls below –0.8°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 34: Overload Prevention

    8-6. Overload Prevention (Heating) Overload prevention prevents overheating of the indoor heat exchange coil. This function works either when the temperature of indoor heat exchange coil goes up or compressor current rises to a certain level. Temperature of indoor heat exchange coil sensor When the temperature of the indoor heat exchange coil rises above A2°C, and if the indoor fan is L (low speed), then the fan speed changes from L (low speed) to M (medium speed).

  • Page 35: Cold Draft Prevention

    8-7. 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. OPERATION lamp on front of the indoor unit flashes when this function is working. Indoor fan operates in LL until indoor heat exchange coil temperature reaches 33°C.
