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 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: Heat source temperature 7 °C and heating water flow temperature 35 °C. 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. Please note that additional space is required for pipe connections, operation and maintenance. The heat circulating pump and the heat pump controller must always be ready for operation. Depending on the type of heat pump and refrigerant, the maximum flow temperatures in heating mode may decline with lower external temperatures. Further information can be found in the heat pump's operating limits diagram.

Note: The maximum possible flow temperature and the operating limits vary by +- 2K due to component tolerances. The minimum volume flow specified in the device information must be ensured at the lower operating limit. In mono energy operating mode with the heating element activated, the maximum flow temperature increases by approximately 3K.
