The direction of action of the controller is determined by the sign of
the P term.
Positive PID control (default):
If the sign of the P term is positive and the process value drops below
the setpoint, the control will increase the pump speed until the set-
point has been reached.
Negative PID control:
If the sign of the P term is negative and the process value drops below
the setpoint, the control will decrease the pump speed until the set-
point has been reached.
NOTE:
Check the controller's direction of action if PID control is being used,
but the pump is only running at minimum or maximum speed without
responding to changes in the parameter values.
Have maintenance and repair work carried out by qualified person-
nel only!
It is recommended to have the pump serviced and checked by WILO
Customer Service.
