Lochinvar 100287202 High Altitude Control Board Kit WHN056

Product Description

The LOCHINVAR 100287202 is a high altitude main control board kit designed for use with the WHN056 unit. This control board serves as the primary electronic management component, coordinating ignition sequencing, burner operation, and system safety functions within the appliance. It is engineered specifically for high altitude installations where combustion air density and pressure conditions differ from standard sea-level operation. Installation is typically performed by a licensed HVAC technician or qualified boiler service professional familiar with the applicable equipment.

This control board kit is intended for high altitude applications where standard control boards are not rated for the reduced air pressure conditions. The WHN056 designation indicates compatibility with that specific Lochinvar unit. Installers working in high altitude regions should confirm local code requirements and equipment altitude ratings before proceeding with any control board replacement.
