1. The operating limit of 7 °C is achieved in the opposite direction.
2. 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.
3. Note that additional space is required for pipe connections, operation and maintenance.
4. 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. A2 / W35: Heat source temperature 2 °C
and heating water flow temperature 35 °C.
5. See CE declaration of conformity
6. The heat circulating pump and the heat pump controller must always be ready for operation.
7. The entered values refer to the operation (heating water/cooling water) in the opposite direction to the flow.
