Tracer® Symbio™ for Enhanced Energy Efficiency and Serviceability

Symbio baner

Controlling large equipment for energy efficiency is critical for focused energy cost management and sustainability initiatives. Decades of global experience in chillers and heat pumps has led to development of the renowned proprietary design Trane Tracer® Symbio™ equipment controller.

It is the industry’s first application-specific and field-programmable controller – providing more flexibility and customizable operation sequences. Building automation systems integration meets industry standards to enable a more integrated process and is made even more flexible with new communication protocol options.

  • Flexibility – as occupant and building needs evolve, Symbio solves present and future challenges. Symbio easily integrates with older systems via open standard protocols.  Upgradeable software also offers proactive cybersecurity updates and future enhancements that comply with changing energy codes.
  • Connectivity – Connected buildings meet occupant demands with ease by allowing secure access to system and equipment data anytime, anywhere. Use data collected by Symbio to remotely monitor, troubleshoot, schedule and control equipment.
  • Serviceability – Symbio can be reprogrammed easily and often with non-proprietary software service tools and built-in interfaces. Users benefit from multi-language support. Utilize detailed event logs, trends, and alarm management to ensure optimized system performance. Symbio automates and streamlines equipment start-up and allows you to remotely diagnose and manage systems.
