point is reached. The I-controller is an accurate but slow controller and leaves no per-
manent control deviation.
The differential term (D term) of the controller does not react to the control deviation,
but only to its rate of change. This affects the rate at which the system responds. In the
factory settings, the D term is set to zero as this is an appropriate setting for a number
of applications.
Only change the parameters in small increments and continuously monitor the effects
on the system. Only a specialist trained in control engineering may adjust the parameter
values.

Table 16: PID parameter
The sign before the P term determines the controller’s direction of action.
Positive PID-Control (default):
If the P term is positive and the process value drops below the setpoint, the control will
increase the pump speed.
Negative PID-Control
If the P term is negative and the process value drops below the setpoint, the control will
decrease the pump speed.
NOTICE
Possible malfunction if the PID control goes in the wrong direction!
The pump only runs at minimum or maximum speed. It does not react to changes in
the parameter values.
• Check controller direction.
