Lochinvar & A.O. Smith 100189284 Control
The Lochinvar & A.O. Smith 100189284 Control is a critical OEM replacement integrated control board engineered specifically for Fire Tube (FTXL) heating boilers, including the FTX850, FTX850L, and FTX850N models. As a veteran technician knows, the SMART SYSTEM control module is the "brain" of the hydronic system, managing flame ignition, burner modulation, and essential safety circuit checks. This board processes real-time data from outlet temperature sensors and flame sense electrodes to maintain high-efficiency condensing operation. It features integrated logic for cascade management, allowing the lead boiler to coordinate up to eight units for balanced lead-lag rotation. The 100189284 provides direct 24V communication to gas valves, blower motors, and pump relays, ensuring precise delta T control. Designed for seamless plug-and-play installation within the existing low voltage connection board, this integrated boiler control replaces legacy or failed modules to restore full system Modbus or BACnet communication and freeze protection protocols.
Product Features:- Specifically engineered for Lochinvar Knight FTXL and FTX850 series boilers.
- Advanced modulation control optimizes firing rates based on system supply temperature demand.
- Integrated safety diagnostics monitor low water cutoff (LWCO) and blocked drain switches.
- Supports multi-temperature loop control and domestic hot water (DHW) priority.
- Compatible with CON·X·US remote communication kits for mobile system monitoring.
- How do I verify if this board is compatible with my FTX model? This 100189284 control board is the standard OEM replacement for FTX850 series boilers. Always check your specific serial number and the SMART SYSTEM version before installation.
- Does this board handle pump staging? Yes, the integrated control module manages boiler pumps, system pumps, and DHW recirculation pumps via internal relay logic.
- What should I check if I have a "No Display" fault? Technicians should first verify the control module fuses (specifically F3) and transformer 24V output before replacing the integrated control.
