The following drawing shows a schematic view of the inverter principle:
Inverter Features The inverter provides the following features:
 The regulating capacity can be changed according to the changes in the outdoor
temperature and cooling load.
 Quick cooling
The rotation speed of the compressor is increased when starting the cooling.
This enables to reach the set temperature quickly.
 Comfortable air conditioning
A fine adjustment is integrated to keep the room temperature constant.
 Energy saving cooling
Once the set temperature is reached, the energy saving operation enables to maintain the
room temperature at low power.
Frequency Limits The following functions regulate the minimum and maximum frequency:
 Compressor protection function. Refer to page 37.
 Discharge pipe temperature control. Refer to page 39.
 Input current control. Refer to page 40.
 Freeze-up protection control. Refer to page 41.
