The operating instructions of the functionally necessary accessories such as hydraulic module or hydraulic station are stored in the "Downloads" tab under "ACCESSORIES".

* The data are only recommendations. Depending on individual circumstances, a heat pump with a lower heating capacity may also be suitable for larger buildings and vice versa. In addition, it is possible to connect several heat pumps together and thus increase the heating capacity. Finally, a precise individual calculation is required to select the really suitable system for the project.
