Trane ZZSENSAL0400AA Sensor
The Trane ZZSENSAL0400AA is a precision-engineered OEM remote wired indoor sensor designed to provide localized temperature data for advanced climate control. In professional zoning applications, relying on a single thermostat location often leads to hot or cold spots; this remote temperature sensor allows the system to average readings across multiple zones or monitor a specific high-priority space. It is a critical component for maintaining the calibration and operational integrity of Trane ComfortLink II and AccuLink systems, including the XL950 (TZONE950) and newer XL1050 (TZONE1050) series. Built with a Negative Temperature Coefficient (NTC) thermistor, it ensures high-accuracy feedback—within +/- 0.5°F at 75°F—to the comfort control module. Its compact, wall-mount design is finished in neutral white for an unobtrusive installation on any interior surface. For maximum performance in residential or commercial mechanical rooms, this sensor supersedes legacy part numbers SEN1337 and SEN01337, ensuring compatibility with CONT402, CONT624, and CONT850 controls.
Key Benefits:- Enhanced HVAC Precision: Provides a +/- 0.5°F accuracy rating at 75°F, allowing for tighter deadband control and reduced equipment cycling.
- Advanced Compatibility: Seamlessly integrates with Trane ComfortLink II XL950 and XL1050 thermostats, as well as American Standard AccuLink systems.
- Temperature Averaging: Supports multi-sensor networks to average indoor temperatures, solving comfort issues in large open-plan areas or multi-story builds.
- Rugged Operating Range: Reliably monitors ambient air within a 20°F to 120°F range, suitable for various residential and commercial conditioned spaces.
- Easy Retrofit: Directly replaces older SEN1337 and SEN01337 models, utilizing standard 18-gauge thermostat wire for connection.
Where is the best location to mount the ZZSENSAL0400AA?
For accurate readings, mount the sensor approximately 5 feet above the floor on an interior wall. Avoid locations near air supply registers, direct sunlight, or exterior doors where drafts may skew data.
Does this sensor require a separate power source?
No, this is a wired remote sensor that receives its low-voltage signal directly from the thermostat or comfort control via the RS2/RS1 terminals.
Will this work with the XL1050 thermostat?
Yes, the ZZSENSAL0400AA is compatible with the 1050 series. Note that when assigned as the primary indoor sensor, it will typically disable the thermostat's onboard sensing to prioritize the remote location's data.
