Trane SEN1449 Sensor

Maintain precise environmental control in high-demand commercial and industrial applications with the Trane SEN1449. As a veteran HVACR technician, you know that consistent feedback is critical for the performance of Trane and American Standard HVAC systems. This 10K Wired Zone Sensor utilizes a high-accuracy 10K ohm thermistor to provide stable temperature sensing, ensuring your Reliatel RTRM or legacy control board receives the exact DC voltage signals required for optimal staging and efficiency.

The Trane SEN1449 features an integrated Fahrenheit Dial for manual setpoint adjustments, allowing occupants to fine-tune comfort without complex programming. Its 3-wire or 2-wire setup (depending on the controller configuration) is designed for rugged performance, minimizing induced voltage and signal loss compared to wireless alternatives. This OEM temperature sensor is built with durable ABS and polycarbonate materials, rated for operating environments between 32°F and 122°F, making it a reliable choice for warehouses, offices, and mechanical rooms.

• Reliable 10K Thermistor: Delivers precise temperature data to minimize short-cycling and improve energy efficiency.
• Manual Setpoint Control: Features a user-friendly dial for individual zone adjustments, reducing calls for simple comfort changes.
• Wired Connection Stability: Eliminates battery maintenance and signal interference common in wireless sensor deployments.
• Broad Compatibility: Engineered as a direct replacement part (formerly SEN00505) for a wide range of Trane and American Standard units.
• Hardwired Durability: Robust construction designed to withstand the humidity and temperature fluctuations of industrial settings.

How do I test the Trane SEN1449 sensor?
Using a multimeter set to VDC, check the terminals at the controller (typically J6-1 and J6-2 on RTRM modules). With the sensor attached, you should see a voltage corresponding to the zone temperature. If testing resistance, ensure the sensor is disconnected and compare the ohm reading against a standard 10K thermistor temperature chart.

What is the maximum wiring distance for this zone sensor?
For optimal signal integrity, the maximum field wiring length should not exceed 200 feet using 18 AWG shielded or unshielded twisted pair wire.

Can this sensor be used for discharge air temperature?
While the SEN1449 is primarily designed as a wall-mounted zone sensor for space temperature monitoring, its 10K thermistor curve is compatible with many Trane controllers that require 10K ohm inputs for various sensing points.
