Resideo Combustion control controller S4965V3283

The Resideo S4965V3283 is a microprocessor-based combustion control controller designed for automating gas burners in industrial and domestic applications. It operates on a 230 V supply and supports flame detection via ionization or UV sensors. The controller manages the full burner sequence, including pre-purge, ignition, flame monitoring, and emergency shutdown. It has a protection class of IP40 and is suitable for gas fuel systems.

When selecting a replacement combustion control of this type, verify the supply voltage, flame detection method (ionization, UV, or IR), and the specific series and type designation to ensure compatibility with the burner's programming and physical mounting. The control must match the existing base or plug pattern, and the safety time and pre-purge settings must align with the burner's requirements. Always compare the part number on the existing unit before ordering.

Typical failures of combustion controls include lockout due to flame detection issues, failure to start or complete the pre-purge cycle, or erratic shutdowns. Symptoms may include the burner not igniting, repeated lockouts requiring manual reset, or the system shutting down unexpectedly. Check the flame sensor, wiring connections, and supply voltage to diagnose the issue.
