Lochinvar 100167840 High Altitude Control Board

Product Description

The LOCHINVAR 100167840 is a high altitude integrated control board designed for Knight Wall Mount Boilers. This board serves as the central electronic controller for the boiler system, managing ignition sequencing, burner operation, and safety lockout functions at high altitude conditions where standard atmospheric pressure settings require adjustment. Licensed HVAC technicians and hydronic heating specialists are the primary installers of this component. The high altitude designation indicates factory configuration for reduced air density environments, making it a direct replacement for installations located at elevation.

This control board is intended for use in residential and light commercial hydronic heating applications utilizing Lochinvar Knight Wall Mount Boilers. It is suited for high altitude installations where standard control boards are not approved for use. Technicians replacing a failed or faulted control board in a Knight Wall Mount Boiler system will install this board as an OEM-style replacement to restore full system functionality.

Key Features

• High altitude configuration for operation in reduced atmospheric pressure environments
• Integrated control manages ignition, burner sequencing, and safety shutoff functions
• OEM-style replacement designed specifically for Knight Wall Mount Boiler platforms
• Direct drop-in fit eliminates field modification of control wiring harness

Compatibility
