Page 11: Ffunction
FUNCTION 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 12 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 13 2) FREEZE PREVENTION 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. ROOM TEMP.
- Page 14 4) DRY OPERATION (DEHUMIDIFICATION) HEAT PUMP MODEL 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 an OFF automatically as shown in the chart below according to the room temperature.
- Page 15 6) DEFROSTING OPERATION (HEAT PUMP MODEL) When the capacity of unit bas been decreased due to frost sticking to the outdoor heat exchanger during heating, the temperature drop gradient is detected by the microcomputer controlled temperature sensing system, and defrosting operation is started. At this time, the indoor and outdoor fan motors wills stop, only the compressor is operated, and the system is automatically changed to cooiling operation mode.
