7-3. Recommended Wire Length and Diameter Regulations on wiring diameter differ from locality to NOTE locality. For field wiring requirements, please refer to Refer to the WIRING SYSTEM DIAGRAM for the your local electrical codes. Carefully observe these meaning of "A" and "B" in Table 6. regulations when carrying out the installation.
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 31
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.
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.
8-4. 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.
8-5. Overload Prevention (Heating) This function prevents overheating of the indoor heat exchange coil. When the temperature of the indoor heat exchange coil rises above 54°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 57°C, the outdoor fan stops.
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. 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.
