Description
The Schneider Electric (Barber Colman) SE8350U5B11 is an advanced room controller engineered for commercial HVAC applications that demand precise environmental management and seamless building automation integration. Housed in a clean white casing and fascia, this controller combines multiple sensing and control functions into a single, wall-mounted device — reducing installation complexity and overall system cost.
Integrated Humidity & Dehumidification Control
The SE8350U5B11 features an onboard relative humidity (RH) sensor paired with dedicated dehumidification control logic. This enables the controller to actively monitor space humidity levels and trigger dehumidification sequences without the need for external humidity sensors or additional control modules — ideal for applications in schools, healthcare facilities, hotels, and other occupancy-sensitive environments.
Passive Infrared (PIR) Occupancy Detection
An integrated PIR (Passive Infrared) sensor provides on-board occupancy detection, allowing the controller to automatically adjust setpoints and HVAC operation based on room occupancy. This built-in feature supports energy savings strategies by reducing conditioning in unoccupied spaces without requiring a separate occupancy sensor.
Universal Outputs for Flexible System Design
Equipped with universal outputs, the SE8350U5B11 accommodates a wide range of HVAC equipment configurations. Universal outputs can be configured for analog or digital signals, providing the flexibility to interface with fan coil units, VAV boxes, heat pumps, and other terminal equipment — simplifying design and reducing the need for additional controllers.
BACnet MS/TP Communication
Native BACnet MS/TP communication ensures seamless integration with building automation systems (BAS) and building management systems (BMS). This open-protocol support allows facility managers and system integrators to monitor, control, and trend all controller data from a central platform, supporting energy management, fault detection, and compliance reporting.
