Max. operating overpressure (heat sink)
1. For air temperatures of -22 °C to 0 °C, flow temperature increasing from 54 °C to 65 °C.
2. When the optional weather protection hood (accessory) is used, the sound power level is reduced by 2 dB(A) and the sound pressure level in outlet direction by 1 dB(A).
3. Tonal component according to DIN 45681 Table 1 is 0 dB
4. The heat output and COP is reduced by approx. 5 % in lower operation
5. 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.
6. 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 param-
eters, in particular the defrosting capacity, the bivalence point and regulation, should also be taken into consideration. These figures are only achieved with clean heat exchang-
ers. Information on maintenance, commissioning 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: 7 °C outside temperature and 35 °C heating water flow temperature.
7. See CE declaration of conformity
8. The heat circulating pump and the heat pump manager must always be ready for operation.
