The control unit constitutes the control of a (hybrid) lifting station or a pumping station for wastewater. Probes, float switches
or pressure sensors can be used to detect the level. When the switching level has been reached, pumping is activated. In
hybrid lifting stations the backwater protection is also activated. If the level has fallen accordingly, pumping is ended auto-
matically and, in hybrid lifting stations, the backwater protection too.

The control unit includes corresponding electrical equipment for intrinsically safe electric circuits.
