Jump response to various control deviations (open control circuit, actuator removed)

Adjustment time Tn = 7 min.

Sample time Tn = 20 sec.

Mixed heating circuit runtime = 2 min.

The P-pulse that brings the mixed heating circuit to the new position and is proportional to the control deviation is followed by additional actuation pulses if the control deviation is not yet remedied (I-part). The adjustment time remains constant despite varying control deviations.

7.3.4.10.1.5Actuator end position function

This function determines the type of control signal in the end positions OPEN or CLOSED of each actuator.

1= Continuous voltage at connection OPEN or CLOSED at the respective end position

2= De-energised at end position OPEN or CLOSED respectively

Recommendation for the basic setting of the adjustment time with different heating systems:
