8 Operation Details
8.1. Basic Function
Inverter 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, 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.

8.1.1. 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.
