The CU 200 control unit is a combined status,
control and communication unit specifically developed for the
SQFlex system. Furthermore, the CU 200 enables connection of a
level switch.
The CU 200 incorporates cable entries for ...
• power supply connection
• pump connection
• earth connection

Communication between the CU 200 and the pump
takes place via the pump power supply cable. This is called
mains borne signaling (or Power Line Communication), and this
principle means that no extra cables between the CU 200 and the
pump are required. It is possible to start, stop and reset
the pump by means of the on/off button
