SQ Flex CU202 Multi Purpose Interface

SQ Flex CU202 Multi Purpose Interface

The Grundfos CU 202 is a control and monitoring unit designed for use with Grundfos SQFlex submersible pumps. It provides pump control, system status, alarm monitoring, and expanded setup options for solar-powered, off-grid, and remote water pumping systems.

The CU 202 comes preconfigured for tank-filling applications and can automatically start and stop the pump when used with a float switch or level sensor. Communication with the SQFlex pump takes place through the existing pump power cable, eliminating the need for a separate communication cable.

Built-in Bluetooth connectivity allows setup, monitoring, and troubleshooting through the Grundfos GO app.
