Lochinvar & A.O. Smith 100167835 Control
The Lochinvar & A.O. Smith 100167835 Control is a critical integrated control board engineered specifically for the Knight WH199 wall-mount boiler series. Designed for peak hydronic heating performance, it serves as the central intelligence for your appliance, managing the firing rate, combustion fan speed, and multi-zone pump logic. This OEM replacement part replaces previous iterations with improved firmware to handle sophisticated modulating burner sequences and 10:1 turndown ratios, ensuring the system operates at its rated 95% AFUE efficiency. As a technician, you’ll find the 120V line voltage terminal strip and low voltage connection points clearly labeled for streamlined field wiring. This HVACR control module provides real-time diagnostic feedback through the Smart System interface, helping you troubleshoot flame sensing issues or blower speed deviations without unnecessary downtime. Because this board coordinates the gas valve and induction blower, ensuring precise negative pressure sensing is vital for safe ignition. Use this factory-certified component to maintain the integrity of the WHB199N combustion cycle.
- Universal Compatibility: Drop-in replacement for Lochinvar Knight WH199 and select A.O. Smith commercial hydronic units.
- Smart System Integration: Full support for multi-color diagnostic displays and Loch-N-Link USB programming for rapid parameter cloning.
- Advanced Modulation: Controls the ECM pump and combustion fan to optimize fuel-to-air ratios across all heating demands.
- Rugged Build: Industrial-grade circuitry designed to survive the high-temperature environment of condensed cabinet designs.
Common Questions & Contractor Insights
Does this board require specialized programming?
Yes. While it is a direct fit for the WH199, technicians must verify local parameters such as altitude settings and pump delays via the Smart System interface or a Loch-N-Link drive during commissioning.
What are the symptoms of a failing 100167835 control?
Common indicators include erratic blower modulation, frequent "Ignition Failure" or "AC Reversed" errors on the UIM, and the inability to maintain set-point temperatures despite a clean burner and functional sensors.
Can I use this board for other Knight series models?
This specific part number is calibrated for the WH199. Using it on boilers with different BTU ratings can cause improper combustion and lockout codes. Always verify the MPN 100167835 against your existing unit's serial plate.
