Lochinvar User Interface Control Board

The Lochinvar User Interface Control Board (also called an interface control board or boiler display control board) is a genuine OEM replacement part for Lochinvar boilers and water heaters. It connects the front-panel user interface to the unit's main integrated control. This lets technicians and operators see system status and adjust settings.

Key Features:

• Communication link: Passes data between the user interface display and the main boiler control.
• Monitoring and setup: Gives access to modulation rates, temperature set points, sensor feedback, and error codes.
• Easier diagnostics: Shows fault messages and configuration menus, which helps with troubleshooting.
• OEM engineering: Made to work with the factory control architecture and the existing connectors and cabling on the unit.
• Hydronic and hot water use: Used on Lochinvar condensing boiler and water heating products.

Typical signs of a failing interface board include a blank or flickering display, unresponsive buttons, or soft lockouts that won't clear. Replacing it with a genuine Lochinvar part helps keep the unit controlling and communicating correctly. After installation, the installer menu may need to be checked to confirm local parameters. Select the child item that matches your unit's control part number.
