SOFREL B4TH: Native BACnet Connectivity for HVAC Control

The SOFREL B4TH is a connected controller designed to regulate and monitor your technical installations.
As the heir to the SOFREL S4TH know-how, it retains all its functionalities while natively integrating the BACnet protocol, a key standard in BMS (Building Management System).

Native BACnet Communication

Thanks to its direct compatibility with BACnet/IP networks, the SOFREL B4TH easily integrates into your existing systems without any gateway or additional adaptation. This guarantees:

Full interoperability with your technical equipment (heating, ventilation, air conditioning…)
Simplified deployment and easier maintenance

Performance & Connectivity

Just like the S4TH, the B4TH ensures precise and reliable regulation of your installations. It also provides advanced remote-control and telemetry functions, allowing you to optimize consumption and guarantee continuous control.

Available in versions 4AI/4DI/2AO/2DO and 8AI/8DI/4AO/4DO, the SOFREL B4TH can be extended with up to 10 I/O extension modules, offering optimal adaptability to any type of installation.
