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 < -0.5°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 < -1.0°C.
• Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature >
Compressor OFF point.

• This mode can be set using remote control and the operation is decided by indoor intake air temperature.
• During operation mode judgment at the beginning of the Auto Mode operation, indoor fan motor (with speed of
Lo-) is running for 30 seconds to detect the indoor intake air temperature.
• The operation mode is decided based on below chart.
• After the operation mode is decided, the unit operation will follow the respective operation mode control.
