Fenwal 35-605201-005 Control

The Fenwal 35-605201-005 is a 24 VAC microprocessor-based direct spark ignition control engineered for precision in gas-fired appliances. As a specialized Euro-Model, this unit is designed for high-performance HVACR applications requiring a 0-second prepurge and a 10-second trial for ignition (TFI). The ignition control module utilizes a robust Noryl gray enclosure and is CE approved, making it a staple for contractors maintaining international or specific OEM configurations. Featuring DETECT-A-FLAME technology, it ensures reliable remote flame sensing and quick response times during the combustion cycle. The integrated diagnostic LED provides real-time feedback, allowing for rapid troubleshooting of ignition lockouts or flame sensing issues. With a wide operating temperature range from -40°F to 176°F, this Fenwal control maintains timing accuracy for natural, LP, and manufactured gas systems. This DSI control is not position-sensitive, offering flexibility for vertical or horizontal mounting in tight service panels where reliable automated ignition is critical for system safety.

• Efficient Ignition Cycle: Features a 0-second prepurge and a 10-second TFI for immediate heat delivery in demanding environments.
• Advanced Diagnostics: On-board LED flashes specific fault codes to identify internal failures, airflow faults, or flame signal errors.
• Universal Fuel Compatibility: Designed to regulate 24V gas valves on natural gas, propane (LP), and manufactured gas burners.
• Technical Resilience: Built with conformal coating to resist moisture up to 95% R.H., protecting the board from non-condensing environmental stress.
• Precise Flame Sensing: Minimum flame current of 0.7 microamps ensures stable operation and prevents nuisance lockouts.

How do I troubleshoot a 3-flash LED code on this module?
A 3-flash sequence typically indicates an ignition lockout. Check the spark gap, verify the high-voltage cable integrity, and ensure the flame sensor is clean and properly positioned within the flame envelope.

Can this Euro-Model replace a standard US 35-60 series control?
While the 35-605201-005 shares terminal configurations with other 35-60 models, it is a Special Euro-Model with specific CE-compliant timings. Always verify that your appliance’s data plate matches the 10-second TFI and 0-second prepurge before installation.

What is the proper way to measure the flame signal?
Use a DC microammeter connected to the FC+ and FC- test pins. A healthy system should draw at least 0.7 microamps; readings below this threshold usually point to poor grounding or carbon buildup on the electrode.
