The D component is set to zero at the factory because this setting is suitable for many ap-
plications.
Change the parameters in small steps only and monitor the effects on the system continu-
ously. Only a trained expert in the field of control engineering may carry out adjustment of
the parameter values.

Table 17: PID parameter
The sign for the P component determines the control's direction of control action.
Positive PID-Control (default):
If the P component is positive, the control system reacts to falling below the setpoint by in-
creasing the pump speed.
Negative PID-Control
If the P component is negative, the control system reacts to falling below the setpoint by re-
ducing the pump speed.
NOTICE
Possible malfunction in case of incorrect direction of control ac-
tion for PID control!
The pump runs only at minimum or maximum speed. It will not react to
changes in the parameter values.
• Check the controller's direction of control action.
