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.
2. Operation with 1 compressors
3. Operation with 2 compressors
4. The specified sound pressure level corresponds to the operating noise of the heat pump in heating operation with a flow temperature of 35°C. The specified sound pressure level
represents the free sound area level. The measured value can deviate by up to 16 dB(A), depending on the installation location.
5. See CE declaration of conformity
6. The heat circulating pump and the heat pump manager must always be ready for operation.
