CU 302 is designed for monitoring and controlling SQE submersible pumps in residential water supply applications. The simple user interface and built-in Bluetooth module ensure easy installation and configuration. The Bluetooth connection to the Grundfos GO app offers extensive setup and monitoring options.
Suitable for
- Domestic ground water intake
- Domestic water pressure boosting
- Ground water intake
CU 302 is pre-configured for constant pressure, which is the most used application, offering a plug-and-pump solution, which saves time on commissioning. For other applications, the controller provides several control modes, which can be selected and set through the Grundfos GO app. Grundfos GO makes the configuration easier and allows installers to set up high-performing systems.
CU 302 communicates with the pump through the power cable. This communication principle is called power-line communication and means that no additional cables are required to the pump. Grundfos GO offers detailed information and logs that help the installer find the root cause in failure situations.
In addition, the controller can use Wi-Fi, GENIbus or Modbus to monitor the system remotely either through Grundfos Connect or another SCADA system. Remote monitoring saves time for inspection of installations. CU 302 is equipped with power and pump connections and offers two configurable inputs and outputs.
