The BASO C661BEA-1C Ignition Control is a specialized 24Vac intermittent pilot ignition module designed for precise atmospheric burner control in commercial and residential HVAC systems. Engineered for high-reliability applications, this unit features a single-try ignition sequence with specific timing parameters: a 4-second pre-purge, a 15-second inter-purge, and a 25-second trial for ignition. Utilizing remote flame sensing technology, the C661BEA-1C ensures flame rectification accuracy, essential for preventing nuisance lockouts in complex mechanical rooms. As a robust electronic ignition pilot control, it effectively manages gas valve sequencing without the need for a standing pilot, increasing overall system efficiency. This board serves as the direct replacement ignition control for legacy models BG1600M00FF-1AA and BG1600M00FF-1AD, providing a drop-in solution for technicians addressing failed ignition sequences. Its no-retry timing logic is critical for specific safety protocols where a single ignition attempt is mandated by the appliance's original design specifications. Key Benefits for Technicians Direct OEM Compatibility: Engineered to replace BG1600M00FF-1AA and BG1600M00FF-1AD without wiring modifications. Precise Timing Logic: Features fixed 4-second pre-purge and 15-second inter-purge cycles to ensure safe combustion chamber venting. Remote Flame Sensing: Separates the sensing probe from the pilot assembly for improved signal stability and easier troubleshooting. Standardized 24Vac Operation: Integrates seamlessly with standard HVAC 24V control circuits and gas valves. Common Questions Is the C661BEA-1C compatible with local flame sensing? No, this specific model is designed for remote flame sensing. Ensure your pilot assembly includes a separate flame rod to provide the necessary rectification signal to the board. What is the behavior if the burner fails to light within 25 seconds? The C661BEA-1C utilizes a single-try ignition sequence with no retry. If the flame rectification signal is not detected within the 25-second trial, the module will lock out to ensure safety. Can I use this to replace a standing pilot system? This is an intermittent pilot ignition control. Converting a standing pilot system to an electronic ignition system requires additional components and must follow the appliance manufacturer's specific conversion guidelines.
