3612 Operation and Control12.1. Basic FunctionInverter control, which equipped with a microcomputer in determining the most suitable operating mode as time passes,automatically adjusts output power for maximum comfort always. In order to achieve the suitable operating mode, themicrocomputer maintains the set temperature by measuring the temperature of the environment and performing temperatureshifting. The compressor at outdoor unit is operating following the frequency instructed by the microcomputer at indoor unit thatjudging the condition according to internal setting temperature and intake air temperature.12.1.1. Internal Setting TemperatureOnce the operation starts, remote control setting temperature will be taken as base value for temperature shifting processes.These shifting processes are depending on the air conditioner settings and the operation environment. The final shifted valuewill be used as internal setting temperature and it is updated continuously whenever the electrical 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 Temperatue < -1.5qC.• Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature > Compressor OFFpoint.12.1.3. Soft Dry Operation12.1.3.1. Thermostat control• Compressor is OFF when Intake Air Temperature - Internal Setting Temperatue < -1.5qC.• Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature > Compressor OFFpoint.12.1.4. Heating Operation12.1.4.1.
