Nz (Neutral Zone) 7187; Min. On Time - Danfoss ECL Comfort 110 Operating Manual

Maintenance
Nz (neutral zone)
Set the acceptable flow temperature deviation.
Set the neutral zone to a high value if you can accept a high variation in flow temperature.
When the actual flow temperature is within the neutral zone, the controller does not activate
the motorized control valve.
The neutral zone is symmetrical around the desired flow temperature value, i.e. half the
value is above and half the value is below this temperature.
Min. on time (minimum activation time of valve actuator
The set value is multiplied by 20 ms (milliseconds). The time is the minimum pulse period for
activation of the valve actuator (gear motor).
The setting should be kept as high as acceptable to increase the lifetime of the valve
actuator.
