1.This data indicates the size and capacity of the system. For an analysis of the economic and energy efficiency of the system, both the bivalence point and the regulation should also be taken into consideration. The specified values, e.g. B10 / W55, have the following meaning: Heat source temperature 10 °C and heating water flow temperature 55 °C.

2.Operation with 2 compressors

3.Operation with 1 compressor

4.Note that additional space is required for pipe connections, operation and maintenance.

5.See CE declaration of conformity

6.The heat circulating pump and the heat pump controller must always be ready for operation.
