Reverse circulation
1. The heat circulating pump and the heat pump controller must always be ready for operation.
2. 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.
3. 2-compressor operating mode
4. 1-compressor operating mode
5. The specified sound pressure level corresponds to the operating noise of the heat pump in heating operation with a flow temperature of 35°C.
6. See CE declaration of conformity
