This data characterises the size and performance capacity of the system. For economic and energy consumption 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: heat source temperature 2°C and heating water supply temperature 55°C.
The heat circulating pump and the controller of the heat pump must be on standby at all times.
