M run (running time of the motorized control valve)
Circuit
All
'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.

Nz (neutral zone)
Circuit
All
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.

Min. act. time (min. activation time gear motor)
Circuit
All
The min. pulse period of 20 ms (milliseconds ) for activation of the gear
motor.

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.
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.
*

The setting should be kept as high as acceptable to increase the
lifetime of the actuator (gear motor).
