The ABB FBVi‑2U4‑4T‑SI controller and the ABB FA‑T sensor deliver a streamlined zone-control package. The controller is a freely programmable BACnet/IP building controller, designed for VAV (Variable Air Volume) zoning applications and equipped with 2 UniPuts™, 4 universal inputs and 4 triac outputs, plus an integrated airflow sensor and dedicated room sensor input. Meanwhile the FA-T is an analog temperature sensor that can be connected directly to the controller to provide zone-temperature feedback and a manual override switch. Together, this combination allows the controller to regulate airflow and temperature based on real-time zone feedback, enabling precise comfort control and energy-efficiency in commercial HVAC systems. The FA-T’s compact passive design complements the advanced networked capabilities of the controller, making the bundle a practical solution for modern HVAC zoning.
