Grundfos CU 200 SQFlex Pump Control Unit

The CU 200 control unit is a combined status, control and communication unit developed specifically for the SQFlex system. It enables connection of a level switch, which can turn off the pump when the water reservoir is full.
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.

The CU 200 incorporates cable entries for:
  • power supply connection
  • pump connection
  • earth connection
  • level switch connection

The CU 200 offers the following alarm indications:
  • Dry running
  • Service needed in case of:
  • No contact to pump
  • Over-voltage
  • Over-temperature
  • Overload
