Lochinvar & A.O. Smith 100208474 Connection Board
The Lochinvar & A.O. Smith 100208474 is a critical low voltage connection board designed for seamless integration with Lochinvar Knight WB51-WB211 series wall-mount boilers. As an authentic OEM boiler control interface, this component manages the essential signal pathways between the primary control logic and external system accessories. Technicians recognize this board as the central hub for terminal connections, ensuring that thermostat calls, sensor data, and modulation signals are processed without impedance. When diagnosing communication errors or intermittent control failures in high-efficiency hydronic systems, replacing a compromised interface with the factory-specified 100208474 connection board is the standard procedure to restore signal integrity. This board is engineered to precise electrical tolerances, preventing the common cross-talk and voltage drops associated with aftermarket alternatives, thereby maintaining the operational safety and sequence of operation required for commercial and residential heating applications.
Technical Benefits for Contractors
- Direct OEM Replacement: Matches the exact footprint and terminal configuration for Lochinvar Knight series boilers, eliminating the need for field modifications.
- Optimized Signal Routing: Specifically designed to handle low voltage wiring connections, reducing the risk of electromagnetic interference in the control circuit.
- Enhanced System Reliability: Restores reliable communication for HVAC control boards, ensuring accurate feedback for outdoor reset and limit controls.
- Durable Construction: Built to withstand the thermal cycles of high-efficiency boiler cabinets for long-term performance.
Common Questions
Which boiler models are compatible with part 100208474?
This board is the specific factory replacement for Lochinvar Knight wall-mount units, specifically models WB51, WB81, WB106, WB151, and WB211.
Does this board handle high-voltage line power?
No, this is a dedicated low voltage connection board designed strictly for signals, sensors, and thermostat interfaces. High-voltage connections are handled via the separate power distribution block.
What are signs that this connection board may be failing?
Typical failure symptoms include lost communication with the user interface, unresponsive external sensors, or the boiler failing to recognize a call for heat despite verified external wiring.
