Each chiller on the RS485 network must have a unique address, generally from 001 to 200 (Default is often 11). Baud Rate: Set the speed, commonly 9600 or 19200 baud.

Set the speed to match your master network (typically 9600 or 19200 bps ).

(Note: Always refer to the specific W3000 interface manual corresponding to your controller version—e.g., v17 or CA13—as addresses can vary, per documents like and.) 5.

Connect the positive line to A (+), the negative line to B (-), and the shield to the reference ground ( GND or Common ) at a single point to prevent ground loops.

The Climaveneta W3000 Modbus system is designed to provide precise control over HVAC equipment, allowing for efficient management of heating, cooling, and ventilation systems. Its compatibility with the Modbus protocol facilitates seamless integration with other devices and systems that support this standard, making it an ideal choice for both new installations and retrofits.

To help refine this integration, could you share the of your Climaveneta chiller or the software version of your W3000 controller? If you are facing a specific communication error, let me know what BMS platform you are using so I can provide targeted troubleshooting steps. Share public link
