Nz (neutral zone)
1x187
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.

Min. act. time (min. activation time gear motor)
1x189

motor.
See Appendix “Parameter ID overview”
