Fenwal 35-655700-201 Control
The Fenwal 35-655700-201 Control is a specialized 24V Hot Surface Ignition (HSI) module engineered to handle critical sequences in gas-fired appliances. This microprocessor-based ignition control manages the combustion blower, monitors the pressure switch for proper airflow, and executes a precise 4-second Trial for Ignition (TFI). Designed for high-demand environments like pool heaters and commercial furnaces, the unit incorporates a 30-second post-purge (PP) cycle to ensure residual gases are cleared from the combustion chamber after a call for heat is satisfied, enhancing system reliability and safety.
Equipped with Quick Connect (Q.C.) terminals, this 35-65 series module allows for efficient field installation and secure wiring. The Fenwal 35-655700-201 includes integral on-board LED diagnostics that provide immediate feedback on system status, such as airflow faults or ignition lockouts. By maintaining a minimum flame sensitivity of 0.7 microamps, this HVAC ignition board ensures stable flame sensing and consistent performance even in challenging conditions. The rugged enclosure is designed to withstand ambient temperatures up to 175°F, making it a robust solution for contractors requiring a precise furnace ignition control module.
Key Benefits- Enhanced Safety: The microprocessor design provides repeatable timing for 4-second TFI and 30-second post-purge to prevent gas accumulation.
- Efficient Troubleshooting: On-board LED diagnostic codes allow technicians to quickly identify faults in the airflow or ignition sequence.
- Versatile Mounting: This non-position-sensitive control can be mounted in any orientation to accommodate tight equipment cabinets.
- Reliable Monitoring: Continuous flame sensing and pressure switch oversight ensure the burner only operates under safe conditions.
What does the LED indicator signify on the Fenwal 35-655700-201?
The diagnostic LED provides flash codes to identify system errors. For instance, a persistent flash might indicate an airflow fault or an internal control failure, allowing for rapid diagnostics without extensive meter testing.
Can I use this module to replace and upgrade older ignition controls?
Yes, this Fenwal 35-655700-201 ignition module is a frequent replacement for various 24VAC HSI systems found in water heaters and boilers, provided the timing and voltage specifications align with the original equipment manufacturer (OEM) requirements.
Why is the 30-second post-purge timing critical for my HVAC system?
The 30-second post-purge ensures the combustion blower runs long enough after operation to clear all combustion byproducts, which protects the heat exchanger and promotes a clean start for the next cycle.
