Siber RF-RS485 is a Modbus communication module that enables the integration and control of Siber ventilation systems in a building automation system. This provides remote access and monitoring of system parameters such as fan speed, temperature and humidity values.

The Siber RS485 device (DFEVORFRS485) is connected to the building management system (BMS) via a wire, in Modbus language, for both reading and writing data. It collects information from the Siber DF EVO central heat recovery ventilation device and the compatible wireless sensors (vapor sensor, carbon dioxide sensor) and controller (wireless multifunctional controller or 4-button controller) that are connected to this ventilation unit with radio frequency signals.

Advantages:

- Integration and control: It enables the integration of different devices into a central system, facilitating their monitoring and control.​

- Reliable communication: The RS485 interface provides long-term and stable data transmission, which is especially useful for larger buildings or industrial facilities.​

- Flexibility: The Modbus RTU protocol is widespread and supported, so the Siber RF-RS485 unit is compatible with devices from many different manufacturers
