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, defrosting
capacity, bivalence point and regulation, should also be taken into consideration. The specified values have the following meaning, e.g. A7 / W35: external air temperature 7 °C
and heating water flow temperature 35 °C.
