Fenwal 35-605606-111 Ignition Module
The Fenwal 35-605606-111 is a high-performance 24V Direct Spark Ignition (DSI) module designed for precise combustion control in gas-fired furnaces, boilers, and water heaters. Engineered with microprocessor-based timing logic, this control manages pre-purge (15 seconds), inter-purge, and trial for ignition (4 seconds) sequences with extreme accuracy. It is built to handle 18 to 30V AC input, making it a rugged OEM replacement ignition control for multi-brand HVACR systems including ICP, Heil, and Tempstar. The module features integrated on-board LED diagnostics to simplify troubleshooting in the field by indicating internal failures or ignition lockouts. With three tries for ignition before safe lockout, it ensures reliable burner operation even in fluctuating conditions. The Fenwal 35-60 series is housed in a fire-retardant Noryl enclosure and supports remote flame sensing with a minimum sensitivity of 0.7 microamps, providing technicians a versatile solution for direct spark applications.
Key Benefits- Enhanced Safety: Automated safe-start and flame-sensing logic ensure the gas valve only remains energized when a proper flame is detected.
- Simplified Troubleshooting: The diagnostic LED indicators provide clear flash codes for common faults like airflow issues or flame loss.
- Universal Versatility: Compatible with natural, LP, and manufactured gases; mountable in any orientation to fit tight furnace cabinets.
- Field Reliability: Features an automatic one-hour reset after lockout to prevent unnecessary service calls during minor environmental fluctuations.
- Technical Resilience: Conformal-coated circuitry protects the microprocessor control from high-humidity HVAC environments up to 95% R.H.
What does the steady LED light mean on the 35-605606-111?
A steady LED typically indicates an internal control failure. If you see this, cycle the 24V power at the thermostat or transformer; if the fault persists, the module requires replacement.
How do I measure the flame current on this module?
Use a DC microammeter connected to the FC+ and FC- test pins. A reading of 0.7 µA or higher is required to maintain a stable flame signal and prevent nuisance lockouts.
Can I replace a local sense module with this remote sense version?
The Fenwal 35-605606-111 supports remote flame sensing (S1 terminal). If replacing a local sense unit, ensure your electrode assembly is configured with a separate flame rod or compatible wiring for proper sensing.
