Lochinvar & A.O. Smith 100208652 Control
The Lochinvar & A.O. Smith 100208652 Control is a precision-engineered manual reset low water cut off (LWCO) designed for high-efficiency hydronic systems. Operating on a 24Vac control circuit, this safety device utilizes a 3/8" NPT probe to monitor water levels within the heat exchanger or header, providing essential protection against dry-fire conditions. The 100208652 model LTB024A-S1 is a standard replacement for Knight fire tube boilers (models KH55 through KH285) and various A.O. Smith commercial water heaters. It features a rugged 4-pin wire harness connection for streamlined integration into the factory control board. By requiring a physical intervention to reset the system after a low-water trip, this HVAC safety control ensures a technician can inspect the system for leaks or pump failures before operation resumes, preventing catastrophic equipment damage.
Key Benefits for Contractors- OEM Compatibility: Exact drop-in replacement for Lochinvar Knight boilers and A.O. Smith equipment, maintaining system certification.
- Manual Reset Safety: Prevents automatic recycling in low-water states, forcing a manual system inspection to identify the root cause.
- Simple Installation: Includes a factory-standard 4-pin wire harness and 3/8" NPT probe for quick mechanical and electrical setup.
- System Protection: Highly responsive 24V low water cutoff logic shuts down the burner immediately upon sensing an air pocket or level drop.
- How do I reset the 100208652 control after a lockout? Once water levels are restored to the proper range, press the physical manual reset button on the housing to close the safety circuit and allow the boiler to fire.
- Is the probe included with the 100208652 control? Yes, this specific part number typically includes the 3/8" NPT probe and the control module as a complete LWCO kit.
- Can this be used on steam boilers? While primarily found on hot water hydronic heating systems and commercial heaters, always verify your specific model's manual to ensure the probe depth and pressure ratings match your application.
