1. The heat circulating pump and the heat pump manager must always be ready for operation.
2. At air inlet temperatures of -20 °C to 0 °C flow temperature rising from 55 °C to 65 °C (see operating limits diagram).
3. These data indicate the size and capacity of the system according to EN 255 (10K at A2) and EN 14511 (5K at A7) without weather-proof protective cover. For an analysis of the
economic and energy efficiency of the system, other parameters, in particular the defrosting capacity, the bivalence point and the regulation, should also be taken into consideration.
The specified values have the following meaning, e.g. A7 / W35: External air temperature 7 °C and heating water flow temperature 35 °C.
4. 2-compressor operating mode
5. 1-compressor operating mode
6. 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.
7. Note that additional space is required for pipe connections, operation and maintenance.
