Schneider Electric (Viconics) VTR8350A5000B Controller

The Schneider Electric (Viconics) VTR8350A5000B Controller is a specialized Line-Voltage Fan Coil Unit (FCU) solution designed for high-performance building automation. This BACnet MS/TP communicating room controller streamlines the management of complex fan coil systems by integrating temperature and on-board relative humidity (RH) sensor control into a single, sleek touch screen interface. Specifically engineered for the LineVoltFCU BACnet HUM White series, this model simplifies multi-speed fan control and valve modulation through native BACnet integration. As a veteral-grade HVAC terminal unit controller, it eliminates the need for external secondary controllers in standard commercial and hospitality applications. The VTR8350A5000B is PIR-ready, allowing for easy field upgrades with occupancy sensors to maximize energy efficiency. Supporting Lua4RC scripting, this controller allows for customized sequences of operation to meet specific ASHRAE performance requirements without requiring complex programming tools. By utilizing the VC3000 Relay Pack, contractors can leverage existing high-voltage wiring, significantly reducing field labor during retrofit projects.

• Native BACnet MS/TP & Modbus: Seamlessly integrates with building management systems for real-time monitoring and advanced energy management.
• Integrated Humidity Control: Specifically designed for humidity sensor applications, including active dehumidification strategies to ensure occupant comfort.
• Retrofit-Ready Design: Minimizes hardware overhead by allowing the re-use of original line-voltage wiring between the unit and the digital interface.
• Programmable Interface: Features a touch screen display with 7-day scheduling and multi-language support for diverse commercial environments.
• Advanced Fan Sequencing: Supports both 3-speed and ECM fan systems to optimize fan coil controller efficiency and lower acoustic noise.

Common Questions

Is the VC3000 Relay Pack required for operation?
Yes, the VTR8350A5000B is part of a two-component system. It must be paired with a VC3000 series relay pack to interface with high-voltage fan motors and valves.

Can I add motion sensing after installation?
While this specific model does not include an onboard PIR sensor, it is PIR-ready. You can install an optional PIR cover or integrate wireless occupancy sensors via a ZigBee module.

What wiring is recommended for the communication bus?
For reliable BACnet MS/TP communication, use 22 AWG shielded twisted pair cable. Ensure proper grounding and termination at the end of the trunk to prevent data packet loss.
