BASO C661AHA-1C Ignition Control

The BASO C661AHA-1C Intermittent Pilot Ignition Control is a 24Vac industrial-grade module engineered for high-demand HVAC gas ignition systems. Designed for remote flame sensing applications, this control board provides an infinite try for ignition, making it ideal for environments where consistent pilot re-ignition is required without manual resets. This unit features no pre-purge or inter-purge delays, allowing for immediate ignition sequences upon a call for heat. As a direct intermittent pilot replacement, it replaces several legacy and OEM controls, including the 20H93, 20H9301, and S1-025-26363-700. The C661AHA-1C operates with a 50/60 Hz frequency and is built to manage pilot gas valve and main burner operations with precision. For contractors performing field service, this 24V ignition module ensures reliable flame rectification and compatibility with various atmospheric and power burner configurations where automatic ignition control is specified.

Key Benefits

• Direct OEM Compatibility: Serves as a drop-in replacement for BG1600M00EK-1AA, BG1600M00EK-1AAC, and common Johnson Controls and York units.
• Infinite Ignition Sequence: Eliminates lockout issues in troublesome environments by providing continuous sequence of operation attempts until flame is established.
• Simplified Installation: Features standard 1/4 inch spade terminals for quick wiring of the transformer, valve, and flame sensor circuits.
• Remote Flame Sensing: Allows for flexible burner geometry by separating the spark electrode from the flame rectification probe.
• Zero Purge Timing: Optimized for systems requiring rapid heat delivery without air-clearing cycles before the spark ignition begins.

Common Questions

Is the BASO C661AHA-1C compatible with local sensing burners?
This specific model is designed for remote flame sensing. If your existing setup uses a single-rod local sensing configuration, you must ensure the flame rectification circuit is properly adapted or use the respective local-sense model.

How does this control handle a loss of flame signal?
Upon loss of flame, the C661AHA-1C immediately re-initiates the ignition sequence. Because it is an infinite try control, it will continue to spark and attempt to light the pilot until the flame is detected or power is removed.

What are the voltage requirements for this ignition board?
This is a 24Vac ignition control. It requires a stable 24-volt power source from a class 2 transformer. Operating it at higher voltages will damage the solid-state circuitry.
