Peco Controls SDP155-008 Dig Display

The Peco Controls SDP155-008 is a high-performance digital display zone sensor engineered for seamless integration into Trane VariTrac zoning, Tracer Summit building automation, and Voyager unitary climate systems. This 10K Type 2 thermistor sensor serves as a direct professional-grade replacement for Trane models X13790464, 419-1120, and SEN01280. Designed for rigorous commercial environments, it features an intuitive LCD for real-time temperature monitoring and a single set-point adjustment for precise local control. The interface includes essential "On" and "Cancel" buttons for timed overrides, alongside a dedicated communication jack for field technician diagnostics. Operating on 24 VAC nominal power, the SDP155-008 ensures accurate data transmission to centralized controllers, supporting enhanced energy management and equipment diagnostics. Its decorator-style poly housing allows for vertical flush mounting on standard 2x4 device boxes, maintaining a low profile while delivering industrial-grade stability.

• Universal Compatibility: Engineered specifically to interface with Trane Unit Control Modules (UCM) and building automation systems.
• Enhanced Local Control: Features a clear digital display and adjustable set-points to allow for precise zone temperature management.
• Field Diagnostic Support: Integrated communication jack provides easy access for technicians to monitor system parameters without removing the cover.
• Flexible Overrides: Includes manual "On" and "Cancel" functionality to manage temporary occupancy requirements and set-point offsets.
• Easy Installation: Standard 24 VAC wiring and a compact housing design simplify the retrofit process for existing Trane sensor footprints.

• Can I use an ohm meter to verify the sensor setpoint? No, the sensor setpoint output requires connection to a powered UCM for accurate functional verification and cannot be tested via standard resistance measurements.
• Does the display illuminate immediately upon wiring to 24V power? The digital display is only enabled once the sensor signal wiring is fully established with the controller; power alone will not activate the LCD.
• What gauge wiring is recommended for long runs? For installations exceeding 75 feet, technicians should utilize 18-gauge, 2-conductor cable for power and 18-gauge, 3-conductor cable for signal leads to prevent voltage drop.
