Grundfos CU-200 SQ Flex Control Box

Grundfos CU-200 SQFlex Controller

For use with utility power or sine wave inverters for AC, or series PV arrays for DC.

A user-friendly interface box that maintains two-way communication with the pump and monitors the operating conditions. Built-in diagnostics indicate faults and dry-running, operating status power consumption and level switch input. Built in system monitor display shows pump operation, full tank, input power (watts), Alarm indicator for dry run, overvoltage, overload, and overtemperature.

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. May be used with the IO-100 and/or IO-102.

The CU 200 incorporates cable entries for:

• power supply connection (pos. 6)
• pump connection (pos. 7)
• earth connection (pos. 8)
• level switch connection (pos. 9).

This controller will NOT work with modified sine wave inverters such as the Xantrex TR series or any of the discount inverters often sold in stores.
