Lennox 17M50 Humidity Sensor

The Lennox 17M50 Humidity Sensor is a high-precision relative humidity (RH) sensor kit designed for seamless integration with Lennox L Connection network building automation systems. Engineering specifically for wall-mount installation, this 17M50 unit (catalog number 17M50, identical to 17M5001) serves as a critical feedback loop for commercial rooftop equipment, including LG, LC, LH, SG, and SC models. It facilitates advanced Humiditrol reheat control or supermarket reheat applications, ensuring moisture levels are maintained within tight tolerances of ±3% RH. This sensor is compatible with the BC1-1 Building Controller and Prodigy Control Systems, providing the necessary data for constant volume bypass and VAV zoning performance. Operating on a 24VAC/VDC power supply, it offers selectable 4-20 mA or 0-10VDC output signals, making it a versatile component for industrial humidity monitoring in data centers, healthcare facilities, and climate-controlled commercial spaces.

• OEM Compatibility: Specifically engineered for Lennox rooftop units and split systems using the L Connection network.
• Precise Moisture Control: Delivers high-accuracy readings (±3% RH) across a 0-100% measurement range for demanding environments.
• System Optimization: Essential for triggering condenser reheat and managing Humiditrol functions to improve indoor air quality.
• Rapid Response: Features a response time of less than 10 seconds, allowing for real-time HVAC adjustments.
• Universal Output: Selectable signaling (4-20mA or 0-10V) ensures compatibility with various building automation systems.

Is the 17M50 compatible with non-Lennox equipment?
While designed for the Lennox L Connection network, the standard 4-20mA or 0-10VDC output allows it to communicate with various third-party electromechanical controllers and building functions.

What is the difference between the 17M50 and 17M5001?
These parts are technically identical. The 17M50 is the current catalog number and can be used as a direct replacement for any 17M5001 application.

Where should the 17M50 be mounted for the most accurate readings?
For optimal performance, the wall-mounted humidity sensor should be located in the return air path or a representative conditioned space, approximately 5 feet above the floor, away from direct drafts, sunlight, or stagnant corners.
