BASO C664BBA-1C Intermit

The BASO C664BBA-1C Intermittent Pilot Ignition Control is a microprocessor-based safety module engineered for indirect burner supervision in 24VAC heating systems. This unit is the direct replacement for BG1600M10FM-1AA and G600KX-1, providing a seamless upgrade for legacy controls. Designed for high reliability, it features a 4-second pre-purge cycle to clear residual gas and an 8-second trial for ignition (TFI) window to ensure safe pilot establishment. As a remote flame sensing module, it utilizes flame rectification to monitor combustion across various gas types, including Natural, LP, and manufactured gases.

For the field technician, the C664BBA-1C simplifies troubleshooting with an onboard diagnostic LED that provides clear status codes. The control handles a 1A pilot valve (PV) and a 2A main valve (MV) load, making it a robust choice for commercial boilers, furnaces, and water heaters. With its intermittent pilot ignition sequence, the pilot only remains lit during the main burner cycle, significantly improving energy efficiency over standing pilot systems. Precise timing and 100% shutoff safety protocols ensure the unit meets rigorous industry standards for modern HVACR applications.

• Direct Cross-Reference: Optimized to replace BG1600M10FM-1AA and G600KX-1 with no mounting adjustments.
• Advanced Diagnostics: Integrated LED indicator reduces downtime by providing instant fault detection and system status.
• Precise Timing: Factory-set 4-second pre-purge and 8-second TFI ensure consistent ignition performance and safety.
• Universal Gas Compatibility: Rated for use with Natural, Liquefied Petroleum (LP), or manufactured gas applications.
• Rugged Reliability: Utilizing microprocessor logic, the control provides stable flame monitoring even in demanding environments.

• What is the difference between local and remote sensing? The C664BBA-1C is designed for remote flame sensing, meaning it requires a separate flame probe rather than sensing through the high-voltage spark electrode.
• Does this module support multiple ignition retries? No, this specific model is a single-trial ignition control without a retry or inter-purge period, ensuring immediate safety shutoff if the pilot is not established within 8 seconds.
• Can I use this for a 120V system? This model is specifically rated for 24V Intermittent Pilot circuits. Do not apply line voltage to the 24V terminals.
