Kromschroder Burner control unit BCU370WI2FEU0D3 88600083

This item is a burner control unit (flame safeguard) from Kromschroder, model BCU370WI2FEU0D3, SKU 88600083. It is designed to manage ignition, flame monitoring, and safe shutdown of gas forced-draft burners in both intermittent and continuous operation. The unit supports flame detection via ionization electrode or UV sensor, and is certified to European standards. It features IP54 protection, a built-in screen for status and error display, error memory, and an optical interface for configuration. The device is part of the BCU 370 series and is intended for use in boilers, industrial furnaces, and similar combustion systems.

When selecting a replacement control unit of this type, the exact series and full type designation must match the original. Critical parameters to compare include supply voltage, safety and pre-purge times, flame detection method (ionisation, UV or IR), and the base or plug pattern. These controls are not interchangeable across series even within the same brand, and fitting a unit with mismatched safety times creates a hazard. Confirm that the replacement corresponds to the original unit's full type code and to the wiring scheme of the existing burner.
