Grundfos CU 202 SQFlex control unit suitable for Solar Pumps
CU 202 is designed for monitoring and controlling SQFlex submersible pumps in solar applications.
The new generation of SQ control units
Grundfos CU 202 and CU 302 offer cutting-edge technology to make monitoring and control of pumps easier for you via Bluetooth and WiFi connection.
CU 202 is a combined status, control and communication
unit designed for the SQFlex system. It can be connected
to a level switch and is designed for SQFlex power range
up to 2500 W and maximum 12.5 A.
CU 202 incorporates cable entries for the following
connections:
• power supply
• pump
• configurable IO ports
TM022217
TM022437
• protective earth.
The communication between CU 202 and the
pump is ensured through the power supply cable.
This is called mains-borne signaling (or power line
communication), which does not require extra cables
between CU 202 and the pump.
CU 202 ensures system monitoring and alarm indication.
The operation can be monitored through the following
indications:
• water reservoir full (level switch)
• pump running
• input power.
CU 202 indicates a number of alarms, including:
• dry running
• service needed:
- no contact to the pump
- overvoltage
- overtemperature
- overload
