Lochinvar & A.O. Smith 100110747 Temperature Assembly

The Lochinvar & A.O. Smith 100110747 Temperature Assembly is a high-precision inlet temperature assembly designed for commercial boilers and water heaters. Engineered to provide accurate thermistor readings, this HVAC replacement part is essential for maintaining proper boiler temperature control and ensuring the system operates within its designed thermal parameters. By monitoring incoming water temperatures, this sensor allows the integrated smart system control to modulate the firing rate, preventing flue gas condensation and protecting the heat exchanger from low-temperature returns.

For veteran technicians, the 100110747 temperature sensor offers a direct-fit solution that eliminates field-modification headaches. It is compatible with a wide range of AO Smith and Lochinvar models, including specialized hydronic and potable water systems. Built with heavy-duty materials to withstand constant thermal cycling, this assembly maintains precise temperature management, which is critical for system longevity and energy efficiency. Replacing a drifted or failed sensor with this OEM-spec assembly restores the unit's ability to provide real-time data to the control board, ensuring consistent performance in demanding high-demand environments.

• Ensures precise temperature management for accurate modulation and system protection.
• Directly compatible with Lochinvar and A.O. Smith commercial boiler and water heater lineups.
• Reduces the risk of boiler condensation by providing reliable inlet temperature readings.
• Constructed for industrial durability to handle high-temperature HVACR applications.
• Simplifies maintenance with a complete inlet temperature assembly design.

• How do I confirm if my sensor is failing? Use a multimeter to check the resistance of the 100110747 thermistor against the manufacturer’s temperature-resistance chart; erratic readings usually indicate a need for replacement.
• Is this assembly suitable for return water monitoring? Yes, this inlet temperature assembly is specifically designed to monitor water entering the heat exchanger.
• Can this part prevent "E30" or "E31" error codes? In many A.O. Smith systems, replacing a faulty temperature assembly resolves errors related to sensor malfunctions or open/shorted circuits.
