Grundfos CU 200 Control Unit for SQ Flex (Max 8 AMPS)

The CU 200 control unit is a combined status, control and communication unit especially developed for the SQFlex system. Furthermore, the CU 200 enables connection of a level switch.

The CU 200 incorporates cable entries for;

Communication between the CU 200 and the pump takes place via the pump power supply cable.

It is possible to start, stop and reset the pump by means of the on/off button.
