7. FUNCTION 7-1. 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 21 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 22: 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 23: 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 24: 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 59°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 61°C, the outdoor fan stops. -
Page 25: 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. STANDBY lamp on front of the indoor unit lights up when this function is working. when 10 minutes has elapsed,the fan speed is automatically switched to set speed regardless of indoor heat exchange coil temperature. -
