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 < 2.7°F.
