13.2 Basic function
Inverter control, which 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 model,
the microcomputer maintains the set temperature by measuring 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 and intake air temperature.
13.2.1 Internal setting temperature
Once the operation starts, remote control temperature will be taken as base vale 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.

13.2.2 Cooling operation
13.2.2.1 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 air temperature – Internal setting temperature >
compressor OFF point.
