SiBE12-908 Main FunctionsFunction and Control 51.3 Automatic OperationAutomatic Cooling / Heating FunctionWhen the AUTO mode is selected with the remote controller, the microcomputer automaticallydetermines the operation mode from cooling and heating according to the room temperatureand setting temperature at the time of the operation startup, and automatically operates in thatmode.The unit automatically switches the operation mode to cooling or heating to maintain the roomtemperature at the main unit setting temperature.DetailedExplanation ofthe Function1. Remote controller setting temperature is set as automatic cooling / heating settingtemperature (18 to 30°C).2. Main unit setting temperature equals remote controller setting temperature.3. Mode switching point are as follows. Heating → Cooling switching point:Room temperature ≥ Main unit setting temperature +3.0 deg. Cooling → Heating switching point:Room temperature < Main unit setting temperature –2.5 deg. Thermostat ON / OFF point is the same as the ON / OFF point of cooling or heatingoperation.4. During initial operationRoom temperature ≥ Remote controller setting temperature: Cooling operationRoom temperature < Remote controller setting temperature: Heating operationEx: When the set point is 25°CCooling Operation → 23°C: Thermostat OFF → 22°C: Switch to Heating OperationHeating Operation → 27°C: Thermostat OFF → 28°C: Switch to Cooling Operation(R9417)Set point +3.0ºCSet point –2.0ºC=Thermostat OFFSet point +2.0ºC=Thermostat OFFHeating OperationSet point –2.5ºCCooling Operation
