Setpoint increase per time unit
The rate of increase of the flow temperature setpoint can be limited to a maximum
(heating up brake). In that case, the maximum the flow temperature setpoint can
increase is the set temperature per time unit (°C per hour). This function …
prevents cracking noises in the piping,
protects objects and construction materials that are sensitive to quick tempera-
ture increases (e.g. antiquities),
prevents excessive loads on the heat source.
In the case of space heating with a pump heating circuit (plant type 6 - x), maxi-
mum limitation of the setpoint increase is not possible.
This function can be deactivated (setting
