5.12 Proportional band (Xp)

Adapting the control characteristic to the plant's behavior (controlled system).
Setting the proportional band for control of the damper actuator of the modulating
burner.
Setting range
1...200
Xp influences the controller's P-behavior.
In the case of a setpoint / actual value deviation of 20 °C, a setting of Xp=20 produces
a manipulated variable corresponding to the damper actuator running time
(Tv = 0, Tn = maximum).

5.13 Integral action time (Tn)

Adapting the control characteristic to the plant's behavior (controlled system).
Setting the integral action time for control of the damper actuator of the modulating
burner.
Setting range
10...500
Tn influences the controller's I-behavior.

5.14 Derivative action time (Tv)

Adapting the control characteristic to the plant's behavior (controlled system).
Setting the derivative action time for control of the damper actuator of the modulating
burner.
Setting range
0...30
Tv influences the controller's D-behavior. If Tv = 0, the controller has no PI behavior.
For setting rules concerning Xp, Tn and Tv, refer to section "Modulating burner control
– setting rules"
