Users should contact a regional Trane office to install updated firmware or request additional information and reference Trane service database number HUB-207592.\nTracer SC is no longer actively developed, tested, or sold. Tracer SC will be considered end-of-life on December 31, 2022. Trane recommends users identify a migration plan to replace the Tracer SC controller with  the Tracer SC+ controller, which can function as a drop-in replacement for Tracer SC, providing significant security upgrades."
