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 48
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.
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.
7-3. Automatic Switching between Cooling and Heating When AUTO mode is selected, the microprocessor calculates the difference between the set temperature and the room temperature, and automatically switches to COOLING or HEATING mode to maintain the desired temperature. Room temp. ≥ Set temp. COOL Room temp.
7-5. Overload Prevention (Heating) This function prevents overheating of the indoor heat exchange coil. (KPAV180R5VAA - MCAV180R5VAA) (KPAV220R5VAA - MCAVR5VAA) 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).
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.

7-8. Outdoor Fan Speed Control (Cooling and Dry Operation) To optimize performance of the air conditioner, the outdoor fan speed is switched automatically according to the outdoor temperature. If the outdoor air temperature falls below B°C, the fan speed switches to LOW. If the outdoor air temperature rises above A°C, the fan speed switches to HIGH.
