Lennox 76M31 Sensor

Lennox 76M31 Sensor

The Lennox 76M31 is a high-precision return air duct relative humidity sensor engineered for demanding commercial and industrial HVACR applications. As a non-communicating duct mount RH sensor, it provides critical real-time moisture data to the Lennox Prodigy and CORE unit controllers, essential for managing Humiditrol reheat systems and supermarket humidity control. Designed for technical reliability, this 24VAC HVAC humidity sensor features a robust 7-7/8 inch probe with a high-impact ABS enclosure, ensuring accurate readings across a 0-100% RH range even in challenging airflow environments. For professional contractors, the 76M31 (also found under C0SNSR30AE) is the OEM standard for maintaining precise latent load management and indoor air quality in Lennox LG/LC/LH/SG/SC series rooftop units.

Key Benefits for Technicians
  • System Compatibility: Direct integration with Lennox IMC, Prodigy, and CORE controllers for seamless condenser reheat governance.
  • Industrial Build: Features a 3/4" diameter sensor probe with a durable NEMA-rated enclosure style for return air duct mounting.
  • High Accuracy: Delivers +/-3% RH precision between 20-95% RH, ensuring stable operation of reheat feature parameters.
  • Wide Operating Range: Rated for temperatures from -10°F to 160°F, making it suitable for a broad spectrum of commercial HVAC maintenance environments.
  • Simplified Wiring: Equipped with standard terminal blocks for 24VAC power requirements (1.5 VA) and easy 0-10VDC output verification.
Frequently Asked Questions

Where should the 76M31 sensor be installed for the most accurate readings?
For optimal performance, install the sensor in the return air duct at least 6 feet away from the unit to avoid turbulent air or localized temperature fluctuations that could skew the relative humidity data.

Does this sensor support Humiditrol and supermarket reheat applications?
Yes, this OEM Lennox sensor is specifically designed to monitor and control condenser reheat for Humiditrol systems. Ensure M3 Parameter 105 is correctly configured to option 3 or 6 during commissioning.

What wiring is required for long distance runs over 150 feet?
On runs exceeding 150 feet, use a local isolated 24VAC transformer and 18AWG minimum shielded twisted-pair conductors to prevent signal degradation and ensure consistent HVAC sensor voltage.
