4.243 Central setpoint compensation
• Limitation of the maximum heat source setpoint adaption
Using central setpoint compensation, the heat source setpoint will be adjusted such
that the temperature at sensor B10 reaches the required value.
The maximum value of the readjustment can be set on this operating line.
Setting range
--- / 0...100
---
Function deactivated (deviations will not be offset)
The controller calculates the difference between the heat demand currently placed on
the heat sources and the common flow temperature effectively acquired by sensor B10.
The previous heat demand is adjusted by this differential (+ / -) and passed to the heat
sources as the new heat demand.
The maximum readjustment can be made on this operating line.
Even if the deviation calls for a larger readjustment, the maximum readjustment made
is the value set here.
The common flow temperature sensor B10 required for the central setpoint compensa-
tion is an auxiliary function (ZuFu12) and must be activated (operating line 157) before
it can be used.
The readjustment can only be made in connection with controllable heat sources.
