6.10.3 Manual selection / Adaption of partial diagrams
A plant diagram consists of several partial diagrams.
It is possible to manually compose the required plant diagram from the respective
partial diagrams.
But it is also possible to modify and adjust partial diagrams of a plant diagram
generated via "Presetting" (5700).
The partial diagrams in the controller are listed in Section "Applications" (see page
52 et. seq.). Also listed in the catalogue are the required operating lines which must
be set to produce the respective partial diagrams, plus the sensors required for the
relevant partial diagram.

Charging pump
D iverting valve
The solar plant storage tank can either be integrated using a diverting valve (with a
collector pump) over via a separate charging pump.
When using a diverting valve, it is always only one heat exchanger that can be
used at a time. Only alternative operation is possible.
When using charging pumps, all heat exchangers can be used at the same time.
Either parallel or alternative operation is possible.

Depending on the selection made, setting of the relay outputs assigns appropriate
extra functions to the basic diagrams. See the Section "Applications".
DHW circulating pump Q4
The connected pump serves as a DHW circulating pump.
Operation of the pump can be scheduled as required on operating page "DHW",
operating line "Release circulating pump".
Collector pump 2 Q16
When using a solar collector, a circulating pump for the collector circuit is required.
