Product Description

The Honeywell BC1000A0220U/E Flame Switch provides dependable flame detection and burner safety control for commercial and industrial combustion systems. It monitors the presence or absence of a flame signal and controls ignition and fuel valve sequences during burner operation. Moreover, its compact plug-in design allows technicians to install or replace the unit quickly, even in legacy burner panels.

This controller operates on 220–230 VAC and supports flame rods, UV detectors, or infrared sensors used in oil and gas burner assemblies. Therefore, engineers can integrate it across a wide range of boilers, furnaces, and heating systems without redesigning existing safety circuits. Its built-in safe-start check ensures the burner never ignites when an unexpected flame signal is detected at power-on, which significantly improves operational safety.
