Description
The CU 362 is the "brain" of the Dedicated
Controls system and is mounted in the control
cabinet front.
The CU 362 can control and monitor up to six
Grundfos wastewater pumps. The pumps can
drain a pit using built-in draining algorithms. The
algorithms are based on a water level measured
by float switches or an analog level sensor.
