Peco Controls SP155-017 Sensor

The Peco Controls SP155-017 is a precision-engineered 10K Ohm wired zone sensor designed for seamless integration with Trane VariTrac zoning, Tracer Summit building controls, and Voyager unitary climate systems. Built to original equipment manufacturer (OEM) standards, this thermistor-based sensor serves as a high-reliability replacement for BAYSENS017B and X1351060901 modules. It features a 10K Type 2 thermistor element that provides accurate temperature monitoring with a tolerance of ±0.2°C at 25°C, ensuring stable feedback for centralized HVAC controllers. The sensor is housed in a durable poly decorator-style enclosure, suitable for standard wall mounting or installation within a 2x4 handy box. Field technicians utilize this model for remote temperature sensing, morning warm-up monitoring, and zone temperature averaging in commercial environments. By maintaining direct compatibility with Trane UCM (Unit Control Module) platforms, the SP155-017 eliminates the need for complex calibration or specialized adapters during field service or system upgrades.

• Direct Trane Compatibility: Engineered specifically to drop into existing Trane Tracer Summit and VariTrac network architectures without compatibility issues.
• High-Accuracy Thermistor: Features a 10K Ohm resistance curve that ensures precise thermal data for effective energy management and equipment diagnostics.
• Versatile Application: Validated for use as a standalone zone sensor, a remote sensor for standard modules, or as part of a temperature averaging circuit.
• Industrial-Grade Build: The rugged poly housing is designed for longevity in commercial office spaces, classrooms, and washdown environments.
• Simplified Wiring: Supports standard low-voltage 24 VAC systems with a straightforward subbase design for rapid field replacement.

What Trane part numbers does this sensor replace?
This unit is a direct replacement for BAYSENS017B, X1351060901, 41901087, and THT01235. It is designed to match the electrical performance of these OEM Trane zone sensors.

Can this sensor be used for temperature averaging?
Yes, multiple SP155-017 sensors can be wired in series-parallel configurations to provide an average temperature reading across a large open zone, which is critical for balancing airflow in large commercial layouts.

How should the sensor be mounted to ensure maximum accuracy?
Technicians should mount the subbase on an interior wall away from direct sunlight, supply air diffusers, or heat-generating equipment. Ensure the wire access hole in the wall is sealed behind the subbase to prevent drafts from affecting the 10K Type 2 thermistor.
