Fenwal 35-605601-005 Control Freon Maintaining a reliable standing pilotThe Fenwal 35 605601 005 is a 24VAC DSI control module designed for precise combustion management in gas fired atmospheric burners. This microprocessor based ignition control eliminates the need for a standing pilot, utilizing a 10 second trial for ignition (TFI) to ensure safe and efficient burner startup. As a direct spark ignition unit, it features a single try for ignition logic with no pre purge (NO PP) or inter purge delays, making it an ideal
