7 Additional model features
7.1 Defrosting
Type of defrosting
Defrosting tray included
7.2 Heating water in device protected against icing
7.3 Performance levels
7.4 Controller internal/external
1. See operating limits diagram
2. This data indicates the size and capacity of the system. For an analysis of the economic and energy efficiency of the system, other parameters, such as, in particular, the defrosting
capacity, the bivalence point and regulation, should also be taken into consideration. The specified values, e.g. A2 / W55, have the following meaning: 2 °C external air temperature
and 55 °C heating water flow temperature.
3. Operation with 1 compressors
4. Operation with 2 compressors
5. See CE declaration of conformity
6. The heat circulating pump and the heat pump controller must always be ready for operation.
