Dedicated to HVAC systems (Heating, Ventilation & Air Conditioning), the connected SOFREL S4TH and B4TH controllers enable regulation, 24/7 monitoring, anomaly alerts, and automation of technical installations.
The SOFREL B4TH incorporates all the functionalities of the S4TH, with the addition of full BACnet IP communication — a key standard in Building Management Systems (BMS).
With SOFREL connected controllers, operators can remotely control their HVAC installations, act on motors, pumps, or valves, and automate building processes.
Our solutions for regulating and monitoring your HVAC installations
SOFREL S4TH
The S4TH remote controller is specifically designed for HVAC systems. Thanks to its dedicated “Heating” functions and integrated communication modems, it enables continuous regulation, 24/7 monitoring, anomaly alerting, and automation of technical equipment. Robust and proven, it constitutes a reliable solution for the energy management of buildings.
SOFREL B4TH
The B4TH connected controller inherits all capabilities of the S4TH and adds 100% native BACnet IP communication. This open protocol, widely adopted in BMS, simplifies integration into modern infrastructures and ensures optimal management of HVAC installations. The B4TH blends high-performance regulation, connectivity, and scalability to sustainably improve buildings’ energy efficiency.
