Peco Controls SP155-027 Sensor

The Peco Controls SP155-027 Zone Sensor is a high-precision field replacement designed for seamless integration with Trane VariTrac, Tracer Summit, and Voyager unitary systems. Engineered to support commercial building automation, this Trane compatible zone sensor features an integrated temperature adjustment slide and a 4-wire CommJack (communication jack) for direct equipment diagnostics and data logging. It serves as a cost-effective alternative to OEM parts such as the Trane X1351060602, maintaining high accuracy in temperature monitoring across designated zones. The hardwired 24V unit includes intuitive On and Cancel buttons, allowing for localized override and setpoint management. Built with a durable vinyl housing and a low-profile wall-mount design, the SP155-027 ensures reliable thermistor performance in high-demand HVACR environments. This sensor is the technician’s choice for restoring full monitoring, energy management, and diagnostic functionality to centralized controllers without the OEM markup.

• Broad Compatibility: Direct drop-in replacement for Trane VariTrac, Tracer Summit, and Voyager climate systems.
• Integrated Diagnostics: The built-in communication jack allows for easy connection to digital controllers and diagnostic tools.
