Lochinvar & A.O. Smith 100167772 Control Module

The Lochinvar & A.O. Smith 100167772 Control Module is a critical OEM replacement part engineered for high-efficiency commercial water heaters and hydronic boiler systems. As a primary digital controller, this module manages the ignition sequence, gas valve modulation, and flame supervision to ensure peak thermal efficiency and operational safety. Designed to interface with the SMART TOUCH and CON•X•US platforms, the 100167772 provides consistent combustion control and system diagnostics, effectively reducing downtime by allowing technicians to monitor flow rates and temperature differentials in real-time. This HVAC control board is a direct replacement for various Power-fin and Armor series models, maintaining system compatibility without requiring field modifications. By consolidating pump relay logic and safety limit monitoring into a single robust unit, this module streamlines HVAC troubleshooting and ensures the long-term reliability of the combustion assembly in demanding mechanical room environments.

• Ensures precise flame supervision and ignition control for consistent burner performance.
• Supports system diagnostics through integrated error code reporting for faster on-site repairs.
• Optimizes energy consumption via advanced modulation algorithms that adjust to load demand.
• Maintains OEM compatibility with Lochinvar and A.O. Smith commercial grade equipment.
• Protects internal components by monitoring flow rates and temperature set points to prevent overheating.

What are the symptoms of a failing 100167772 control module?
Common indicators include "No Display" on the user interface, persistent ignition failure lockout codes, or the system failing to modulate the gas valve despite a call for heat.

Is this a direct replacement for older Lochinvar control boards?
While the 100167772 is a standard replacement part, always verify your specific model and serial number, as it is designed to replace specific revisions within the Power-fin and Armor product lines.

Does this module control the system and boiler pumps?
Yes, the 100167772 integrates pump relay logic, managing the timing and operation of the boiler, system, and domestic hot water (DHW) pumps based on the programmed parameters.
