Excess heat draw can be triggered from some other device via bus or through storage
tank recooling.
Ex
cess heat draw
When dissipat
ion of excess heat is activated, it can be drawn by space heating. This
can be selected separately for each heating circuit (H1, H2, H3).
Off.
Excess heat draw is deactivated.
On.
Excess heat draw is activated.
Ex
cess heat draw is active only if the respective Hx input is defined as a heat request
or heat request 10 V input.
If there is a buffer storage tank, it must be stated whether the Hx circuit can draw heat
from it.
With buffer
When making use of alternative heat sources, the buffer storage tank temperature is
used as a control criterion for the release of additional heat sources.
No
Hydraulically speaking, the consumer group is connected upstream of the buffer
storage tank and cannot draw any heating or cooling energy from it. The heat or
refrigeration request is forwarded to the heat / refrigeration source upstream of the
buffer storage tank.
Yes
The consumer group is connected downstream from the buffer storage tank. It draws
heating or cooling energy from the buffer storage tank and its temperature request is
taken into account by buffer management.
The setting defines whether the primary controller / system pump has an impact on the
consumer group.
With primary c
ontroller /
system pump
No
Hydraulically speaking, the consumer group is connected upstream of the primary
controller / system pump and cannot draw any "precontrolled" heating or cooling
energy. The heat or refrigeration request is always forwarded to the heat / refrigeration
source upstream of the primary controller.
