1. See operating limits diagram
2. These data characterize the size and performance of the system. For economic and energetic reasons, additional factors such as defrosting behaviour, bivalence point and control
need to be taken into consideration. Abbreviations have the following meaning, e.g. A2 / W55: outside temperature 2 °C and heating water supply temperature 55 °C.
3. See EC Declaration of Conformity
4. The heating circulating pump and the controller of the heat pump must be on standby at all times.
