7 Complies with the European safety regulations
8 Additional model features
8.1 Water in device is protected against freezing
8.2 Max. operating overpressure (heat source/heat sink)
9 Heat output / COP
9.1 Heat output / coefficient of performance (COP)
1. Operating limits must be observed in the project planning stage. For detailed information, see the operating limits diagram. Operating restrictions are to be expected in the
event of non-compliance.
The intended use is within the operating limits shown. The heat pump is optimised for the application of space heating in accordance with EN14825. For projects involving
continuous operation with heat-source infeed temperatures of greater than +17 °C, the operating limits shown are to be complied with using downstream hydraulic equipment,
for example.
2. Tonal component according to DIN 45681 Table 1 is 0 dB
3. The specified sound pressure level corresponds to the operating noise of the heat pump in heating operation at 55 °C flow temperature.
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.
4. Note that additional space is required for pipe connections, operation and maintenance.
5. These data indicate the size and capacity of the system according to EN 14511. For an analysis of the economic and energy efficiency of the system, the bivalence point and
regulation should be taken into consideration. These specifications can only be achieved with clean heat exchangers. Information on maintenance, commissioning and oper-
ation can be found in the respective sections of the installation and operating instructions. The specified values, e.g. B0 / W55, have the following meaning: Heat source tem-
perature 0 °C and heating water flow temperature 55 °C.
6. See CE declaration of conformity
7. The heat circulating pump and the heat pump manager must always be ready for operation.
8. The coefficients of performance are valid with the circulating pumps included in the scope of supply.
