Fenwal 35-705601-001 Control
The Fenwal 35-705601-001 is a microprocessor-based Direct Spark Ignition (DSI) control engineered for precision in 120 VAC gas-fired heating applications. This Fenwal ignition module features a 4-second Trial for Ignition (TFI) period, ensuring safe flame establishment before lockout. Designed with zero pre-purge (NoPP) and inter-purge timings, it provides immediate ignition response upon a call for heat. The 35-705601-001 utilizes remote flame sensing (RMT SNS) to verify burner operation, allowing for flexible electrode placement in complex combustion chambers. As a 120V DSI control, its solid-state circuitry offers superior timing accuracy compared to legacy analog models. The board includes on-board LED diagnostics to streamline troubleshooting for service technicians, identifying flame failure or internal faults instantly. With its polarity-insensitive design and robust 1/4-inch quick-connect terminals, this HVAC ignition board is a reliable choice for maintaining high-efficiency commercial and residential appliances.
Key Benefits- Precise timing: Microprocessor control ensures +/- 5% timing accuracy for 4-second TFI sequences.
- Remote sensing: Compatible with separate flame sensors for specialized burner configurations.
- Diagnostic LED: Simplifies field service with clear flash codes for rapid error identification.
- Instant ignition: Configured for zero pre-purge, reducing total cycle time during startup.
- Installation flexibility: Features polarity insensitive wiring to prevent damage during field replacement.
What does 'NoPP' signify for this control?
'NoPP' stands for No Pre-Purge, meaning the control energizes the gas valve and spark immediately without a blower delay.
How do I test the flame signal on the 35-705601-001?
Use a DC microammeter connected to the FC+ and FC- test pins; a minimum of 0.7 µA is required for consistent operation.
Can this replace a local sense ignition module?
This model is specifically for remote sense applications; if converting from local sense, the electrode wiring must be adjusted accordingly.
