If the temperature level of the buffer storage tank is high enough, the consumers
draw the heat they require from the buffer storage tank. The heat/refrigeration
source is put into operation only if the buffer storage tank is no longer capable of
satisfying the current heat/cooling demand.
None
There is no heat generation lock based on buffer storage tank temperature.
A consumer's heat request is forwarded directly to the heat generation.
With B4
If the temperature at sensor B4 is high enough, the heat source is locked. The
consumers draw the heat they require from the buffer storage tank.
If the temperature at sensor B4 is too low, a heat request is passed on to the
producers.
With B4 and B41 / B42
If the temperature at both sensors B4 and B41 (or B42) is high enough, the heat
source is locked. The consumers draw the heat they require from the buffer
storage tank.
If the temperature at both sensors B4 and B41 (or B42) is too low, a heat request is
passed on to the producers.

The settings in detail
A buffer storage tank can be integrated in the plant. Can
be heated by heat generation or solar energy.
In the case of active cooling, it can also be used for storing
cooling energy.
The controller controls heating / cooling and forced
charging of the buffer storage tank, protects it against
overtemperatures and maintains stratification whenever
possible.
