3.5 BMS Integration (Modbus-RTU)
For advanced control and monitoring, the HMI WING EC can be integrated into a Building Management System (BMS) via Modbus-RTU protocol. Refer to the Modbus communication protocol documentation for register addresses and data points.
- Ensure the Modbus A and B terminals are correctly connected to your BMS.
- Configure the Modbus address and baud rate settings on the HMI WING EC panel to match your BMS system.
- The panel acts as a Modbus slave device, allowing the BMS to read status and control parameters.
4. Maintenance
4.1 Cleaning
To ensure optimal performance and longevity of your HMI WING EC control panel, regular cleaning is recommended.
- Before cleaning, always disconnect the power supply to the device.
- Use a soft, dry, lint-free cloth to wipe the display and casing.
- For stubborn marks, slightly dampen the cloth with water or a mild, non-abrasive cleaning solution. Do not spray liquids directly onto the panel.
- Avoid using harsh chemicals, abrasive cleaners, or solvents, as these can damage the display or casing.
