Lochinvar & A.O. Smith 100111012 Electronic Control
This genuine Lochinvar & A.O. Smith 100111012 Electronic Control is a critical microprocessor-based controller designed specifically for BTH400NL commercial water heaters. As a primary digital display control board, it manages the combustion process, monitors safety limit strings, and provides real-time diagnostics for high-efficiency systems. This module is the direct replacement for the legacy 9006235005 control board, ensuring seamless integration with existing internal wiring harnesses. For a technician, this replacement control board is essential for restoring precise temperature modulation and responding to BTH error codes. It handles advanced logic for both natural gas and propane configurations, maintaining water heater efficiency through high-authority sensors. By replacing a malfunctioning 100111012 electronic control, you ensure the appliance operates within its original factory parameters, protecting the heat exchanger from thermal stress and optimizing the burner firing rate for consistent hot water delivery in high-demand commercial environments.
Key Benefits- System Compatibility: Engineered for direct fitment in Lochinvar BTH400NL and equivalent A.O. Smith commercial units.
- Advanced Diagnostics: Features an integrated LCD interface to quickly identify fault codes and system status.
- Operational Precision: Utilizes microprocessor logic to coordinate the blower, igniter, and gas valve for optimal combustion.
- Reliable Monitoring: Continuously checks the flame signal and high-limit switches to ensure safe daily operation.
- Will this 100111012 board replace a 9006235005? Yes, this is the current manufacturer-authorized replacement for that older part number.
- How do I troubleshoot a blank display on the BTH400NL? First, verify the 24V power supply at the transformer; if power is present but the screen is dead, the 100111012 control module likely requires replacement.
- Is this control board compatible with both LPG and Natural Gas? Yes, the electronic control is designed to manage the gas sequence for both fuel types, provided the gas valve and orifices are correctly configured.
