Main Functions
SiUS04-924
Function and Control 13
The compressor rotational speed is increased when starting the heating (or cooling) operation. This
enables a quick set temperature.
Even during extreme cold weather, a high capacity is achieved. It is maintained even when the
outdoor air temperature is 36°F(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 maintains the room
temperature at low power.
