2. These data indicate the size and capacity of the system according to EN 14511 (5K at A7). For an analysis of the economic and energy efficiency of the system, other parameters,
in particular the defrosting capacity, the bivalence point and the regulation, should also be taken into consideration. These specifications can only be achieved with clean heat
exchangers. Information on the maintenance, start-up and operation can be found in the respective sections of the installation and operating instructions. The specified values
have the following meaning, e.g. A7 / W35: External air temperature 7 °C and heating water flow temperature 35 °C.
