3012. Operation Control12.1 Basic FunctionInverter control, which equipped with a microcomputer in determining the most suitable operation mode as timepasses, automatically adjusts output power for maximum comfort always. In order to achieve the suitable operationmode, the microcomputer maintains the set temperature by measuring the temperature of the environment andperforming temperature shifting. The compressor at outdoor unit is operating following the frequency instructed bythe microcomputer at indoor unit that judging the condition according to internal setting temperature and intake airtemperature.12.1.1 Internal Setting TemperatureOnce the operation starts, remote control setting temperature will be taken as base value for temperature shiftingprocesses. These shifting processes are depending on the air conditioner settings and the operation environment.The final shifted value will be used as internal setting temperature and it is updated continuously whenever theelectrical power is supplied to the unit.12.1.2 Cooling Operation12.1.2.1 Thermostat control Compressor is OFF when intake Air Temperature - Internal Setting Temperature < -2.7F. Compressor is ON after waiting for 3 minutes, if the Intake Temperature - Internal Setting Temperature >Compressor OFF point.12.1.3 Soft Dry Operation12.1.3.1 Thermostat control Compressor is OFF when Intake Temperature - Internal Setting Temperature < -3.6°F. Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature >Compressor OFF point.12.1.4 Heating Operation12.1.4.1 Thermostat control Compressor is OFF when Intake Temperature - Internal Setting Temperature > +3.6°F.
