Inverter Features
The inverter provides the following features:
The regulating capacity can be changed according to the changes in the outside
temperature and cooling/heating load.
Quick heating and quick cooling
The compressor rotational speed is increased when starting the heating (or cooling). This
enables a quick set temperature.
Even during extreme cold weather, the high capacity is achieved. It is maintained even when
the outside temperature is 2°C.
Comfortable air conditioning
A detailed adjustment is integrated to ensure a fixed room temperature. It is possible to air
condition with a small room temperature variation.
Energy saving heating and cooling
Once the set temperature is reached, the energy saving operation enables to maintain the
room temperature at low power.
