1. This data indicates the size and capacity of the system according to EN 255 and EN 14511. 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. These specifications can only be achieved with clean
heat exchangers. Information on maintenance, start-up and operation can be found in the respective sections of the installation and operating instructions. The specified values,
e.g. A2 / W55, have the following meaning: 2 °C external air temperature and 55 °C heating water flow temperature.
