2. This data indicates the size and capacity of the system according to EN 255 or EN14511. 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. The specified values, e.g. A2 / W55, have the following
meaning: 2 °C external air temperature and 55 °C heating water flow temperature.
