Fenwal 35-615516-111 Module
The Fenwal 35-615516-111 is a high-performance 24 VAC microprocessor-based direct spark ignition (DSI) control module optimized for precision burner management in gas-fired heating systems. This veteran-grade HVAC ignition control is engineered with an integrated inducer blower relay, simplifying the wiring stack while ensuring robust control over the combustion process. Specifically designed for applications requiring a 15-second pre-purge and inter-purge sequence, this module enhances system safety by clearing the combustion chamber of residual gases before initiating the 4-second Trial for Ignition (TFI).
Built for the rigors of commercial and industrial environments, the Fenwal 35-615516-111 features a 3-try ignition sequence to minimize nuisance lockouts and maximize uptime in demanding heating cycles. Its remote flame sense capability allows for flexible electrode placement, ensuring consistent monitoring via DETECT-A-FLAME technology. The SMT (Surface Mount Technology) design provides superior vibration resistance and reliability across a broad temperature range of -40°F to 176°F. Contractors and technicians rely on this DSI module for its rapid 0.8-second flame failure response time and multi-color LED diagnostic codes, which streamline field troubleshooting and verify flame signal strength during commissioning.
Key Benefits for Technicians:- Enhanced Reliability: The microprocessor-based control provides 3-try ignition attempts, reducing service calls related to temporary ignition failures in cold starts.
- Integrated Blower Control: Built-in inducer blower relay and airflow switch monitoring reduce the need for external components and complex wiring harnesses.
- Precision Diagnostics: On-board LED indicators provide instant status updates and fault codes, identifying issues like pressure switch failures or internal logic errors.
- Flexible Monitoring: Supports remote flame sensing and provides flame current test pins (FC+, FC-) for accurate microamp signal measurement during routine maintenance.
- Industrial Build Quality: Conformal coating protects internal circuitry from moisture and contaminants common in boiler rooms and rooftop units.
What is the minimum flame current required for this module?
The Fenwal 35-615516-111 requires a minimum flame current of 0.7 microamps (µA) to maintain stable operation and prevent flame-out lockouts.
Can I use this module to replace a 1-try ignition system?
Yes, as long as the 24V supply, TFI timing (4 seconds), and purge requirements match the original equipment manufacturer (OEM) specifications. The 3-try sequence offers a more robust ignition profile for many older systems.
How do I troubleshoot a 3-flash LED code?
A 3-flash fault code typically indicates an ignition lockout after the three attempts have been exhausted. Check the gas supply, spark gap (typically 1/8 inch), and high-voltage ignition cable integrity.
