‘M run’ is the time in seconds it takes the controlled component to move
from fully closed to fully open position.
* See Appendix “Parameter ID overview”
Set the ‘M run’ according to the examples or measure the running
time by means of a stop watch.
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.

When the actual flow / duct temperature is within the neutral zone, the
controller does not activate the motorized control valve.
* See Appendix “Parameter ID overview”
Set the acceptable flow /duct temperature deviation.
Set the neutral zone to a high value if you can accept a high
variation in flow temperature.
The neutral zone is symmetrical around the desired flow / duct
temperature value, i.e. half the value is above and half the value is
below this temperature.
