  • Page 38: Dry Operation

    7-2. 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 39: Freeze Prevention

    7-4. 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 40: Overload Prevention

    7-5. Overload Prevention (Heating) This function prevents overheating of the indoor heat exchange coil. When the temperature of the indoor heat exchange coil rises above B°C, and if the indoor fan is L (low speed), then the fan speed changes from L (low speed) to M (medium speed). When the temperature of the indoor heat exchange coil rises above A°C, the outdoor fan stops.

  • Page 41: Cold Draft Prevention

    7-6. 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.
