Lochinvar & A.O. Smith 100110233 Control

The Lochinvar & A.O. Smith 100110233 Control is a heavy-duty automatic temperature reset limit control designed for high-demand commercial water heaters and hydronic boilers. This genuine OEM component, manufactured by APCOM, serves as a direct drop-in for legacy part numbers 11B06-10 and 9005044205, ensuring seamless integration with existing 3/4-inch tank openings. Engineered to maintain rigorous safety parameters, it features an adjustable temperature range of 100°F to 240°F with a precise 5°F to 45°F differential, allowing technicians to fine-tune thermal cycling for maximum efficiency. The assembly includes the required 7855 immersion well (also referenced as 9005078205), providing a complete aquastat replacement solution for Lochinvar, State, and American water heater systems. Focused on circuit reliability, this limit control board prevents over-temperature conditions by automatically resetting once the tank fluid returns to the safe operational range, minimizing downtime for critical facility infrastructure.

• Broad Compatibility: Direct OEM cross-reference for 11B06-10, 9005044205, and 93661-4.
• Integrated Immersion Well: Includes the 7855/9005078205 well for rapid installation and accurate thermal transfer.
• Adjustable Thermal Precision: Field-adjustable setpoints from 100°F to 240°F to meet specific load profiles.
• Automatic Reset Logic: Eliminated manual intervention requirements after temporary high-limit excursions.
• Industrial Grade Build: Designed by APCOM to withstand the continuous cycling of commercial gas water heaters.

• What is the difference between this and a manual reset? This 100110233 control automatically closes the circuit once the water temperature drops below the differential setting, whereas manual limits require a physical reset after tripping.
• Does it include the mounting well? Yes, the package includes the compatible immersion well specifically designed for a 3/4-inch NPT tank connection.
• Is this compatible with State or American brand heaters? Yes, because A.O. Smith is the parent manufacturer, this part is the standard A.O. Smith replacement control for several State and American commercial units.
