Control modes
The CUE has a built-in PID controller that provides
closed-loop control of the value you want to control.
The CUE can also be set to open-loop control where
the setpoint represents the desired pump speed.
Open loop is typically used without sensor. All other
contr
ol modes require a sensor.
The table below shows the functions and possible set-
tings offered by the CUE.
