Function and Control 105
3.2.7 Compressor Step
The compressor operation frequency is controlled in order to keep a constant evaporation
temperature in cooling and a constant condensing temperature in heating.
Cooling t cool = Remote controller set temperature - Indoor return air temperature.
Depending on t cool and the cooling load, the target evaporating temperature will be a value
between 2°C and 20°C.
Heating t heat = Indoor return air temperature - Remote controller set temperature.
Depending on t heat and the heating load, the target condensing temperature will be a value
between 42°C and 54°C. (for RZQG100-140L : 42°C and 50°C)
