Lochinvar & A.O. Smith 100111038 Controller
The Lochinvar & A.O. Smith 100111038 Combined Controller is the critical integrated command module designed specifically for the BTH 120 100 and BTH-120/A series natural gas water heaters. As a veteran-grade commercial water heater control board, this OEM replacement part (formerly identified as part number 9006262005) manages the sequence of operation, ignition timing, and safety parameter monitoring for high-efficiency condensing systems. It features a high-visibility LCD interface for real-time diagnostic reporting and error code troubleshooting, allowing for precise field adjustments of setpoints for both potable water and hydronic heating applications. Built to withstand the thermal demands of heavy-duty commercial environments, this digital controller ensures consistent BTU output regulation while monitoring the blower motor, burner assembly, and temperature sensors. For contractors maintaining gas-fired water heaters, this unit is the standard for restoring factory-spec operational efficiency and combustion stability in the field.
Key Benefits- Direct OEM Compatibility: Engineered specifically for the Lochinvar BTH series and A.O. Smith Cyclone models to ensure seamless electrical communication.
- Advanced Diagnostics: Features on-board fault code displays that simplify troubleshooting and reduce technician diagnostic time.
- Integrated Logic: Consolidates ignition control and temperature monitoring into a single combined controller for streamlined wiring and system reliability.
- Precision Thermal Management: Maintains tight differentials to optimize energy consumption and prevent unnecessary cycling of the commercial furnace or boiler.
Is this controller backward compatible with older BTH models?
This unit is the manufacturer-designated replacement for the 100111038 and obsolete 9006262005 parts. It is essential to verify your specific series number (e.g., Series 100) before installation to ensure harness compatibility.
What are the primary causes of failure for this control module?
Most HVAC control board failures in commercial settings result from localized power surges, moisture infiltration in the cabinet, or loose wiring connections at the terminal block. Always check the slow-blow fuses (F1, F2, F3) before replacing the entire module.
Does this board require specialized programming during installation?
While the board is pre-calibrated for the BTH-120 100 series, technicians should always verify the configuration settings on the LCD display to match the specific application requirements and venting lengths of the existing installation.
