BASO C664FGA-1C Control

The BASO C664FGA-1C is a reliable intermittent pilot ignition control engineered for continuous retry applications in gas-fired heating equipment. Operating on a 24V AC ignition module platform, this control features a 0.5-minute retry period and an 85-second trial for ignition (TFI), ensuring stable flame sensing and burner sequence management. Designed for 100% shut-off in the event of flame failure, it provides precise electronic ignition control for systems requiring a dependable spark-to-pilot sequence without a prepurge period. This unit serves as a high-spec HVAC replacement part, maintaining system uptime by managing both the pilot and main gas valves. As a drop-in direct replacement ignition control, it simplifies field service by eliminating the need for wiring modifications when upgrading from legacy Johnson Controls or BASO units. Its robust internal circuitry is built to withstand the electrical noise and thermal cycling typical in commercial and residential furnace environments.

Key Technical Benefits

• Direct Replacement Compatibility: Specifically engineered to replace BG1600M11ER-1AD, BG1600M11ER-1ADC, and G775RHA-2 models.
• Sequence Optimization: Features a 0.5-minute retry timing with 0-second prepurge for rapid heat call response.
• Universal Voltage Support: Standard 24V (18-30 VAC) 50/60 Hz power input integrates seamlessly with existing transformer outputs.
• Field Reliability: High-performance flame rectification circuit reduces nuisance lockouts in challenging draft conditions.

Common Questions

How do I troubleshoot a lockout on the BASO C664FGA-1C?
Verify the 24V supply to the module and inspect the pilot assembly for carbon buildup. If the intermittent pilot ignition fails to sense flame within the 85-second TFI, the unit will cycle for a retry. Ensure the ground circuit is secure, as this control relies on flame rectification through the pilot burner.

Does this unit require a specific pilot burner?
The C664FGA-1C is compatible with most standard intermittent pilot burners. However, for optimal flame signal strength, ensure the electrode gap is set to manufacturer specifications and the high-voltage lead is not routed near low-voltage thermostat wiring.

Can I use this to replace a G775 series control without a prepurge requirement?
Yes, this model is a direct functional equivalent for the G775RHA-2. Since this module has a 0-second prepurge, it is vital to confirm that the appliance manifold design allows for immediate ignition upon pilot gas flow.
