•••• Airflow direction, Fan speed and Setting temperature areoptimized.•••• “[Intake Air temperature] - [Remote controller settingtemperature]” is detected every 30 seconds by indicationfrom indoor unit and controlled to each area.Quick Heating → Unit forcibly turns to Quick Heating operationfor 5 minutes after Powerful-ON even through it is in the WarmHeating area.Warm Heating → Discharge air temperature iskept high by changing fan speed according to roomtemperature and warm feeling will be produced.9.7.3. Heating Operation9.8. Automatic Operation•••• Operation mode (Cooling, Dry and Heating) is automatically selected.•••• Operation mode is selected at the beginning of unit operation and every 30 minutes. Temperature, fan speed and airflowdirection are set with the remote controller.•••• During cooling mode operation, if Dry mode is selected in next operation mode selection, the operation will be Cooling Dry.9.8.1. Operation Mode SelectionOperation mode is selected according to outdoor air temperature, intake air temperature and setting temperature.1. "Heating" is selected when outdoor air temperature is below 16°C.2. "Cooling" is selected when intake air temperature is 25°C or more. (But, when intake air temperature is 16°C or more.)3. When outdoor air temperature is below 25°C, if remote controller setting temperature is increased, selectable range of“Heating”, if decreased, selectable range of “Heating” will be extended respectively.31CS-HE9DKE CU-HE9DKE / CS-HE12DKE CU-HE12DKE
