Excess heat draw can be triggered by the following functions:
-
Input H1, H2 or EX2
-
Storage tank recooling
-
Solid fuel boiler excess heat draw
When dissipation of excess heat is activated, it can be drawn by space heating. This
can be adjusted separately for each heating circuit.
If there is a buffer storage tank, this defines whether the H1/H2/H3 circuit can draw
heat from it.
When using alternative heat sources, the buffer storage tank temperature is used as a
control criterion for the release of additional heat sources.
This defines whether the H1/H2/H3 circuit receives its heat via the primary controller or
with the help of the system pump (depending on the type of plant).
2-pipe system
The cooling circuit with Hx and the heating circuits demand cooling/heating from the
same primary circuit.
4-pipe system
The cooling circuit with Hx and the heating circuits demand cooling/heating from
separate primary circuits.

Before buffer st tank
After buffer st tank
If the plant uses a buffer storage tank, it is to be set here whether, hydraulically, the
primary controller or the system pump is installed upstream from the buffer storage
tank.
