Product Description
MNL-V1RV3-2 Schneider TAC I/A MicroNet LonWorks VAV Terminal Box Controller Integral Actuator 12VA
MNL-V1RV3-2 Schneider TAC I/A MicroNet LonWorks VAV Terminal Box Controller Integral Actuator 12VA
Product Overview
The MNL-V1RV3-2 is a LonMark VAV terminal box controller from the TAC I/A Series MicroNet generation. While this product line has been discontinued, it remains in service across numerous buildings commissioned in the 2000s. Its key feature is the integration of all functions into a single package: the damper actuator, velocity pressure transducer, and controller are combined into one assembly that mounts directly over the damper shaft. This eliminates field wiring, alignment issues, and calibration drift associated with separate components, contributing to its exceptional longevity in service.
The "version two" suffix identifies the revised hardware that replaced the original MNL-V1RVx part numbers, making it the preferred variant for spare parts replacement in existing installations. The controller provides pressure-independent control, ensuring consistent airflow delivery regardless of duct pressure variations, and can operate either standalone or as a peer on a LonWorks FTT-10 free topology network.

System Integration Notes
The over-the-shaft mounting design enables quick installation but requires careful attention during replacement: shaft diameter and extension must match precisely, and the 3/8 inch shaft option requires the appropriate adapter kit rather than forced installation.
Since the transducer is integral, the high and low pressure taps consist of short tubing runs from the flow station. Tubing length limitations are critical—kinked or excessively long runs can produce stable but inaccurate airflow readings.
Configuration is performed using WorkPlace Tech software. Replacement controllers require the existing application file rather than fresh configuration, unless original engineering records are unavailable. On the network, the free topology wiring is polarity insensitive for convenience, but proper segment termination and single path routing remain essential to avoid intermittent communication faults.
Application Scenarios
These controllers are primarily used as replacement parts in existing buildings with VAV terminal boxes rather than new installations. Common applications include:
- Commercial office floors with pressure-independent boxes and reheat coils in existing LonWorks installations
- University and hospital buildings where control infrastructure is being maintained rather than replaced
- Sites undergoing staged migration to BACnet, allowing individual floors to remain operational during transition
- Museums, laboratories, and archival storage facilities where airflow stability takes precedence over control platform age
This maintenance strategy is particularly valuable for facilities that cannot accommodate simultaneous downtime across all systems.
