Program List and Explanations
The point of intersection of the tangent with the respective axis will
result in the parameters a and L.
Consult the manual of the control unit for connecting and program-
ming details. Choose control upwards or downwards.
If Control upwards or Control downwards is active

Control Parameters
5.2.1.43.10
Setpoint:
User-defined process value (Measured value or flow)

P-Band:
Range below (upwards control) or above (downwards con-
trol) the set-point, within the dosing intensity is reduced from 100%
to 0% to reach the set-point without overshooting.
