Fenwal 35-605928-215 Control

The Fenwal 35-605928-215 is a high-performance 24V direct spark ignition control module engineered for gas-fired equipment including commercial boilers, water heaters, and furnaces. This microprocessor-based unit delivers precise sequencing with a 30-second pre-purge, a 10-second trial for ignition (TFI), and a 15-second ignition period. Designed for the field technician, it utilizes Detect-a-Flame technology for continuous flame supervision and features on-board diagnostics via a system LED to streamline troubleshooting. This DSI ignition control supports both local and remote flame sensing and is compatible with natural, manufactured, and LP gas types. With an operating range of -40°F to 176°F, the Fenwal 35-605928-215 ignition module ensures stable performance in high-demand environments. The inclusion of flame sense test pins allows for real-time monitoring of micro-amp signals without breaking the circuit, making it a reliable HVAC replacement part for critical heating applications.

• Precision Timing: Microprocessor control ensures consistent 30s pre-purge and 10s TFI intervals for safe burner start-up.
• Advanced Diagnostics: Built-in LED provides clear fault codes, reducing downtime during service calls.
• System Versatility: Direct spark ignition (DSI) design supports a wide variety of 24 VAC atmospheric or power-vented gas appliances.
• Reliable Monitoring: Features dedicated flame current test pins for accurate micro-amp measurement and rapid system characterization.
• Rugged Construction: Encapsulated electronics protect against moisture and vibration in demanding boiler rooms or commercial kitchens.

How do I troubleshoot a lockout on this Fenwal 24V module?
The integrated diagnostic LED will flash specific codes indicating the failure mode, such as no flame signal, pressure switch failure, or internal circuit faults. Refer to the standard Fenwal fault code table to isolate the issue.

Can this control be used with both local and remote flame sensing?
Yes, the 35-605928-215 is designed to support both local (through the spark electrode) or remote (using a separate flame rod) sensing configurations depending on the appliance wiring.

What are the power requirements for this ignition module?
The unit operates on a 24 VAC (18-30 VAC) 50/60 Hz supply. Ensure your transformer has sufficient VA capacity to handle both the module and the gas valve load.
