Fenwal 35-605601-101 Control

The Fenwal 35-605601-101 is a robust 24V Direct Spark Ignition (DSI) control engineered to provide precise microprocessor-based timing for gas-fired appliances. This unit is designed for field-service reliability, featuring a 15-second pre-purge cycle to clear the combustion chamber and a 4-second Trial for Ignition (TFI) period. Encased in a durable Noryl gray enclosure, the module utilizes an edge connector for secure wiring and incorporates DETECT-A-FLAME flame sensing technology to ensure safe burner operation. The 35-605601-101 supports single ignition attempts and is compatible with natural, manufactured, and LP gas. For streamlined troubleshooting, the board includes a diagnostic LED and flame current test pins (FC+ and FC-), allowing technicians to measure the 0.7 microamps minimum signal required for stable operation. This microprocessor ignition module is not position-sensitive, offering flexible horizontal or vertical mounting options for diverse HVACR applications.

Key Benefits:

• Precision Timing: Microprocessor control ensures repeatable 15sec PP and 4sec TFI cycles.
• Diagnostic Clarity: Integrated LED error codes and flame sense test pins reduce diagnostic time at the job site.
• Environmental Resilience: Conformal-coated circuitry operates in non-condensing environments up to 95% R.H.
• Safety Logic: Features a safe start check and immediate 0.8-second response to flame failure.
• Universal Fuel Compatibility: Approved for use with LP, Natural, and mixed gases.

Common Questions:

What is the minimum flame current for the Fenwal 35-605601-101?
The system requires a minimum flame sense signal of 0.7 microamps to prevent safety lockout.

How do I reset the module after a lockout occurs?
This DSI control is reset by interrupting the 24VAC power supply at the thermostat or primary power source for at least 5 seconds.

Does this module support local or remote flame sensing?
The 35-605601-101 is designed for remote flame sensing, utilizing a separate electrode to monitor the burner flame.
