Lochinvar & A.O. Smith 100208560 Inlet Sensor Kit
The Lochinvar & A.O. Smith 100208560 Inlet Sensor Kit is a critical OEM inlet / DHW temperature sensor designed for precision thermal monitoring in high-efficiency hydronic heating systems and commercial water heaters. This kit provides the necessary feedback for the control board to manage modulating boiler firing rates and domestic hot water delivery. As an essential component for system diagnostics, the Lochinvar 100208560 ensures that inflow data is processed accurately to maintain condensing efficiency and prevent thermal overshoot. For contractors servicing Knight boilers or A.O. Smith Cyclone series units, using this genuine replacement part is mandatory to ensure sensor resistance curves match factory specifications, avoiding nuisance lockouts or improper mixing valve operation.
Key Benefits for Technicians
- Precise NTC Thermistor Calibration: Provides accurate DHW temperature monitoring to maintain consistent setpoints and system safety.
- OEM Compatibility: Engineering specific to Lochinvar and A.O. Smith equipment, ensuring the sensor housing and electrical connectors seat perfectly for a moisture-tight seal.
- Optimized System Modulation: Enables the control board to execute finer adjustments to boiler temperature control, maximizing energy savings in condensing applications.
- Direct Fit Installation: Replaces faulty or corroded sensors without the need for field modifications, reducing labor time on site.
Common Questions
What are the symptoms of a failing 100208560 inlet sensor?
Common indicators include erratic DHW temperatures, "Sensor Open" or "Sensor Short" error codes on the control interface, and the system failing to enter modulation despite high demand.
Can I use a generic thermistor instead of this kit?
It is not recommended. This inlet sensor kit is calibrated to a specific resistance-to-temperature curve required by the manufacturer's firmware; generic sensors often lead to inaccurate readings and efficiency loss.
Is this sensor compatible with both residential and commercial units?
Yes, this 100208560 sensor is utilized across various Lochinvar and A.O. Smith platforms, including high-recovery commercial water heaters and high-efficiency residential boilers.
