Xp (proportional band)
Circuit
All
* See Appendix "Parameter ID overview"
Set the proportional band. A higher value will result in a stable but
slow control of the flow / duct temperature.

Tn (integration time constant)
Circuit
All
* See Appendix "Parameter ID overview"
Set a high integration time constant (in seconds) to obtain a slow
but stable reaction to deviations.
A low integration time constant will make the controller react fast
but with less stability.

How to calculate the running time of a motorized control valve
The running time of the motorized control valve is calculated using
the following methods:
Seated valves
Running time = Valve stroke (mm) x actuator speed (sec. / mm)
Example: 5.0 mm x 15 sec. / mm = 75 sec.
Rotating valves
*
Running time = Turning degrees x actuator speed (sec. / degr.)
Example: 90 degr. x 2 sec. / degr. = 180 sec.
