Grundfos CU202 Control Unit

CU202 is a combined status, control and communication unit designed for the SQ Flex system.  The CU202 enables the connection of a level sensor or a float switch
placed in a water reservoir or tank to provide automatic control for the pump. 

CU202 is designed for SQ Flex power range up to 2500W and maximum 12.5A.

CU202 incorporates cable entries for the following connections:-

·       power supply

·       pump

·       configurable IO ports

·       protective earth

The communication between CU202 and the pump is ensured through the power supply cable. This is called mains-borne signalling (or power line communication), which does not require extra cables between CU202 and the pump.

CU202 ensures system monitoring and alarm indication. The operation can be monitored through the following indications:-

·       water reservoir full (level switch)

·       pump running

·       input power

CU202 indicates a number of alarms, including:-

·       dry running

·       service needed:
- no contact to the pump
- overvoltage
- overtemperature
