12. Operation Control
12.1 Basic Function
Inverter control, which equipped with a microcomputer in determining the most suitable operation mode as time
passes, automatically adjusts output power for maximum comfort always. In order to achieve the suitable operation
mode, the microcomputer maintains the set temperature by measuring the temperature of the environment and
performing temperature shifting. The compressor at outdoor unit is operating following the frequency instructed by
the microcomputer at indoor unit that judging the condition according to internal setting temperature and intake air
temperature.
12.1.1 Internal Setting Temperature
Once 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 value will be used as internal setting temperature and it is updated continuously whenever the
electrical power is supplied to the unit.
12.1.2 Cooling Operation
12.1.2.1 Thermostat Control
 Compressor is OFF when intake Air Temperature - Internal Setting Temperature < -1.5°C.
 Compressor is ON after waiting for 3 minutes, if the Intake Temperature - Internal Setting Temperature >
Compressor OFF point.
12.1.3 Soft Dry Operation
12.1.3.1 Thermostat Control
 Compressor is OFF when Intake Temperature - Internal Setting Temperature < -2.0°C.
 Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature >
Compressor OFF point.
12.1.3.2 iAUTO-X Operation
 iAUTO-X operation can be set using remote control.
 This operation is applied to faster cool down time of the room and comfort feel by thermal shift and fan speed
control.
 Thermal control
o The internal setting temperature will shift 1°C lower than remote control setting temperature for maximum
4 hours to provide extra cool and better comfort.
o After providing 4 hours of fast cooling, the unit continues to provide comfort cooling according to human
presence and activity detection.
