Si04-115 General FunctionalityMain Function 331.12 Automatic OperationThe unit automatically switches the operation mode to cooling or heating to maintain the roomtemperature at the main unit setting temperature.Detailedexplanation of thefunction1. 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 plus correctionvalue (correction value / cooling: 0 deg, heating: 2 deg.).3. Operation ON / OFF point and mode switching point are as follows. Heating → Cooling switching point: Room temperature ≥ Main unit setting temperature+2.5 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 operationHowever, in the automatic Powerful cooling/heating mode, the guard timer is set as follows toprevent hunting in cooling / heating mode.Heating /cooling switching point 2.5 deg.or higher(Heating thermostatOFF point)Main unit settingtemperature(Cooling thermostatOFF point)Cooling /heating switching point Coolingoperation Heatingoperation CoolingoperationWith compressor capacity suppliedWith no compressor capacity supplied(1.5 deg.)or higherLess than(1.5 deg.)2.5 deg.or higher(R1918)
