If your facility is still operating on a Tracer Summit system, it’s important to plan ahead. These controllers reached legacy status in 2014 and are no longer manufactured, meaning long-term support depends on remaining parts availability.

At Hunton Services, we help building owners modernize strategically, not all at once. Our recommended upgrade path begins by replacing the BCU(s) with Tracer SC, creating a modern system backbone. From there, proprietary controllers can be upgraded to BACnet MS/TP open-protocol controllers through a phased approach that minimizes disruption while extending the life of your BAS.

Many legacy BAS installations also rely on LON technology and aging field devices that are becoming increasingly difficult to support. As these systems age, parts availability, serviceability, technician familiarity, and compatibility with newer technologies continue to decline. We help you navigate these challenges with a practical modernization strategy that improves reliability, expands system capabilities, and prepares your building for future analytics, connectivity, and control technologies.
