Resideo 121371L Well Assembly
The Resideo 121371L Well Assembly is a precision-engineered immersion well designed for accurate thermal sensing in hydronic heating systems and water heaters. Constructed from high-grade copper, this assembly ensures rapid heat transfer and reliable performance for temperature control sensors. It features a 3-inch insertion depth and a 3/8-inch internal diameter, making it compatible with a wide range of standard remote bulb controllers and electronic sensors. The 1/2-inch NPT connection provides a secure, leak-proof fit into tanks or piping manifolds. This specific Resideo sensor well includes a heavy-duty mounting clamp to ensure the sensing element remains firmly seated against the well wall, preventing air gaps that cause lag in temperature readings. For contractors performing retrofits or new installations, the 121371L offers a standardized solution for protecting HVAC temperature sensors from high-pressure fluid environments while maintaining high-sensitivity thermal tracking.
Key Benefits
- High Thermal Conductivity: Copper construction facilitates near-instantaneous temperature response for hydronic temperature controls.
- Standardized Fit: The 1/2" NPT threaded connection integrates seamlessly into existing boiler and water heater ports.
- Secure Mounting: Included clamp prevents sensor drift, ensuring consistent thermal well performance and accuracy.
- Pressure Protection: Isolates the sensing bulb from the system fluid, allowing for sensor replacement without draining the system.
Common Questions
What is the maximum bulb diameter for the 121371L?
This well is designed for sensing bulbs with a diameter of up to 3/8-inch, ensuring a tight fit for standard Resideo and Honeywell Home controllers.
Can this immersion well be used in potable water systems?
Yes, the copper construction and lead-free design make it suitable for domestic hot water and potable applications as well as closed-loop hydronic systems.
Does this assembly include the heat-conductive compound?
While the kit includes the mounting clamp for mechanical contact, applying a thermal paste is recommended to further reduce response time in critical HVACR applications.
