Grundfos CU200 controller

The Grundfos CU200 controller is a device used to control and monitor the SQFlex pumping system.

• It allows visualizing the status and operation of the SQFlex pumping system on a screen.
• It has alarm indications in case of failures or problems in the system.
• It displays symbols of the available power supply options for the system (solar, wind, generator, or electrical grid).
• It has a connection for a level switch that stops the pump when the tank is full.
• It communicates with the pump through the power cable, without the need for additional cables.

The Grundfos CU200 controller requires minimal maintenance.

It is recommended:

• Clean the surface of the controller with a soft, dry cloth when necessary.
• Ensure that cable connections are tight and free of corrosion.
• Protect the controller from moisture, dust, and extreme temperatures.
