    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 3 minutes by the remote control unit to the controller in the indoor unit.
  • Page 24 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 3 minutes by the remote control unit to the controller in the indoor unit.

  • Page 25: 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 26: Freeze Prevention

    8-4. Freeze Prevention (Cooling) 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 –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.

  • Page 27: Cold Draft Prevention

    8-6. 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. As shown in the chart below, indoor fan speed automatically changes depending upon indoor coil temperature. STANDBY lamp on front of the indoor unit lights up when this function is working.
