This professional-grade direct spark ignition (DSI) control board serves as the primary electronic controller for managing the ignition sequence and gas flow in high-efficiency heating systems. By utilizing a high-voltage spark to ignite the main burner directly, it eliminates the need for a standing pilot light. The module features continuous flame monitoring and integrated safety protocols, including an automatic lockout function in the event of ignition failure, ensuring consistent and safe furnace performance.
Type: Ignition Control Board
Size: Medium
Application: Designed for use in residential and commercial gas-fired forced-air furnaces, rooftop units (RTU), and unit heaters. Specifically engineered for systems requiring direct spark ignition and modulating heating cycles.
Specifications: Integrated flame sensing technology, automated pre-purge and post-purge timing sequences, diagnostic LED status indicators, and support for modulating gas valves to optimize thermal efficiency.
