Kromschroder Burner control unit IFD244-3/1W 84621025

The Kromschroder IFD244-3/1W is a burner control unit designed for direct ignition and monitoring of gas burners in intermittent operation, requiring shutdown once every 24 hours. It operates with a supply voltage of 230 V AC and uses an ionization electrode for flame detection. The safety time on start-up is 3 seconds, and it features restart after flame failure. This unit is certified to CE and DIN EN ISO 9001 standards and is intended for grounded systems.

Parts of this type are selected by matching the supply voltage, flame detection method, and safety time to the burner system's requirements. Installation involves ensuring the control unit is compatible with the burner's grounding and wiring, and mounting is typically arbitrary with prepared holes for cable entry. Before ordering, verify the model designation and type designation against the existing unit to ensure correct fit.

Common failure modes for burner control units include failure to ignite, flame loss during operation, or repeated lockouts. Symptoms may include the burner not starting, shutting down unexpectedly, or displaying an error code. Check the ionization electrode for proper positioning and cleanliness, and verify the supply voltage and wiring connections.
