Description
The Fenwal 35‑615900‑227 is a professional‑grade 24 VAC Direct Spark Ignition (DSI) control module designed to reliably manage ignition sequencing, flame sensing, and inducer blower control in gas‑fired HVAC systems and industrial applications. This microprocessor‑based ignition control is engineered to ensure safe, efficient burner start‑up and ongoing combustion monitoring for furnaces, boilers, water heaters, and other gas‑burning equipment.
Key Features
- 24 VAC Direct Spark Ignition (DSI) Control with microprocessor logic for dependable timing and operation.
- 30‑second pre‑purge and inter‑purge intervals for safer combustion preparation.
- 15‑second trial‑for‑ignition (TFI) to initiate spark and light the burner.
- DETECT‑A‑FLAME flame sensing for enhanced safety and verification.
- Inducer blower relay control and airflow switch monitoring for proper combustion airflow coordination.
- On‑board diagnostics with LED indicators and flame test points for easier troubleshooting.
- Supports local or remote flame sensing and automatic reset/alarm output.
