Description
The Fenwal 35 605601 105 Ignition Control Module and its equivalent listings are professional grade 24 VAC Direct Spark Ignition (DSI) control modules designed to deliver precise ignition sequencing, reliable flame sensing, and advanced diagnostics for gas fired heating equipment. Built with a microprocessor based control circuit, this module ensures consistent performance and safe combustion in furnaces, boilers, water heaters, and other gas appliances.
Key Features
- 24 VAC Direct Spark Ignition (DSI): Efficiently ignites burners using an electronic spark, eliminating the need for a standing pilot light and improving system reliability.
- 15 Second Pre Purge: Clears combustion air path before ignition to ensure safer and cleaner starts.
- 10 Second Trial for Ignition (TFI): Provides a controlled window for flame establishment before lockout, enhancing safety.
- Detect A Flame Flame Sensing: Built in flame sensing verifies combustion presence and supports safe operation.
- On Board Diagnostics: LED indicators simplify troubleshooting and system diagnostics for faster service workflows.
- Remote or Local Flame Sense: Flexible flame detection options adapt to different ignition configurations.
- Robust Construction: Conformal coating helps withstand demanding HVAC environments and high humidity conditions.
