Solar controlling element
In place of a collector pump and diver-
ting valves for integrating the storage
tanks, the solar plant can also be ope-

External solar exchanger
In the case of solar plants with 2 stora-
ge tanks, it must be selected whether
there is an external heat exchanger
used for both the DHW and the buffer
storage tank, or for 1 of them only.
Combi storage tank
Functions specific to combi storage
tanks are activated with this setting. For
