Description
The Lennox 27A07 DSI Ignition Control Board is an electronic operating component used to manage direct-incompatible heating equipment. It processes input from connected sensors and systems, then coordinates the sequence of burner and flame verification during startup and normal operation. The board continuously monitors system status and responds to conditions based on programmed logic and control parameters. In HVAC systems, it is installed within the electrical compartment, where it manages communication between related components, supports structured firing sequences, and helps maintain consistent operational performance throughout the heating cycle.
