Lochinvar & A.O. Smith 100111329 Relay Switch
The Lochinvar & A.O. Smith 100111329 Relay Switch is a critical OEM 24 VAC control component engineered for high-recovery commercial water heaters and hydronic boiler systems. This genuine relay replacement manages the sequential activation of heating elements and integrates seamlessly with the Smart System control panel to maintain precise water temperature setpoints. Designed for heavy-duty cycling, the 100111329 relay facilitates power distribution to the combustion air blower and ignition controls, ensuring the system achieves optimal thermal efficiency while providing necessary safety interlocking for HVACR applications. Utilizing this factory-direct switch ensures compatibility with specific Lochinvar and A.O. Smith models, preventing the timing errors or voltage drops often associated with generic aftermarket alternatives. For technicians troubleshooting multi-stage firing or louver proving issues, this 120V/24VAC relay serves as a reliable solution for restoring pilot circuit integrity and water heater operational stability in demanding environments.
Key Benefits:- OEM Precision: Specifically calibrated for Lochinvar and A.O. Smith commercial units to ensure exact electrical timing.
- Enhanced Durability: Built to withstand high-frequency switching cycles in hydronic and HVACR systems.
- System Safety: Functions as a primary control interface for burner operation and safety limit monitoring.
- Seamless Integration: Features standard pin configurations for rapid field installation and technical troubleshooting.
- What are the symptoms of a failing 100111329 relay? Common signs include heating elements failing to energize, intermittent "no heat" errors, or the control board failing to prove the ignition sequence.
- Is this relay switch compatible with all Lochinvar boilers? No, this is a model-specific OEM part. It is essential to verify your unit's serial number and production record before installation.
- Does this part handle the main power load? This relay typically acts as a pilot duty or control circuit switch, directing 24V signals to higher-amperage contactors or gas valves.
