BASO C161AAA-1C Ignition Module

The BASO C161AAA-1C Ignition Module is a high-performance 24V Direct Spark Ignition (DSI) control designed for precise burner supervision in commercial and residential heating systems. Engineering for reliability, this microprocessor-based DSI module features a 0-second pre-purge (0PP) sequence, a 4-second trial for ignition (TFI), and a 30-second inter-purge interval. Utilizing remote flame sensing via flame rectification, the C161AAA-1C ensures stable 100% shutoff safety performance across all gas types, including natural gas and LP.

For field technicians and contractors, this unit serves as the direct replacement for G760AAD-2, BG1100M0AK-1G, and G760AAD-1. Its integrated diagnostic LED simplifies troubleshoot ignition module procedures by providing clear flash codes for system status. The BASO carbon-copy replacement design features standard spade terminals and multiple mounting hole positions that align with legacy Honeywell and Fenwal footprints, streamlining HVAC ignition control upgrades without requiring extensive bracket modifications.

• Advanced Diagnostics: Onboard LED provides real-time ignition control troubleshooting data to reduce site time.
• Drop-in Replacement: Directly replaces obsolete Johnson Controls G760 series and BG1100M0AK-1G modules.
• Rugged Construction: Built to withstand operating temperatures from -40°F to 176°F in demanding mechanical rooms.

Common Questions

How do I test the flame signal on the C161AAA-1C?
Technicians can measure the flame current by placing a microammeter across the two FC test pins while the burner is lit. A minimum reading of 0.8 µAmp DC is recommended for reliable operation.

What does it mean if the diagnostic LED is flashing?
The LED flash codes indicate specific fault conditions, such as a flame-out during a cycle or an internal hardware failure. Always refer to the wiring label for the specific pulse count meanings during ignition module repair.

Can I use this module to replace a local sensing ignition control?
The C161AAA-1C is configured for remote flame sensing. If your existing setup uses the spark electrode for sensing (local), you will need to install a separate flame probe or utilize a compatible local-sense module.
