ESIE12-06 Function DetailsFunction and Control 101Dew condensation prevention controlDry operation with horizontal airflow is carried out for 1 hour. (P2)Note: 1. When there is any change to heating/fan modes, airflow direction and operation ON/OFFstate during dew condensation prevention control, this control is reset.3.1.8 Freeze-up Prevention ControlThe unit will perform the forced thermostat off function in following conditions:Thermostat off due to freeze-up prevention.Based on the judgement to prevent the indoor heat exchanger from freezing, the thermostatis forcedly turned OFF.*1 FHQG Only3.1.9 Monitoring ControlWhen the indoor unit fan is turned off while the thermo. for cooling, heating and drying is off,even if the indoor unit temperature recovers afterwards and becomes the one that turns thethermo. on, the thermistor cannot detect indoor unit temperature because the suction airthermistor of indoor unit is installed inside the machine.In order to prevent such a condition, this monitoring control has the function of detecting indoorunit temperature by operating the fan at certain intervals when the fan is turned off while thethermo. is off.3.1.10 Defrost ControlWhen the heating operation continues at a low outdoor air temperature, the frost adhered to thesurface of outdoor heat exchanger deteriorates heating capacity.When the amount of adhered frost exceeds a certain level, the operation will automaticallyswitch to the cooling cycle to melt the frost.When the frost is melted, the normal heating operation will be resumed.3.1.11 Draft Avoidance ControlIn order to prevent cold wind from directly blowing to the user when the indoor heat exchangertemperature is low, such as the timing that heating started and defrost ended, this control hasthe function of changing the airflow rate to LL tap and fixing the airflow direction to horizontal.Freeze-up prevention control-3ºC-5ºC-1ºC7ºC Cumulative timer cleared after a continuous 20 minutes4ºCThe thermostat turns OFF after a continuous 1 minuteafter 8 minutes from startup (1)The thermostat turns OFF after a continuous 1 minuteafter 8 minutes from startupThe thermostat turns OFF after a cumulative 40minutesReset after a continuous 10 minutes and cumulativetimer cleared after a continuous 10 minutesIndoor unitheat exchangertemperature
