Brahma Control box DMN12 37521000

The Brahma DMN12 control box (SKU 37521000) is a microprocessor-based burner management system for atmospheric gas and oil burners with two-stage regulation in intermittent mode. It automates ignition, flame monitoring, and safe shutdown, featuring manual reset, two independent safety contacts on the gas valve output, and flame loss response in under one second. Compatible with burners from Riello, Baltur, Weishaupt, Lamborghini, and others, it is used in heating and steam boilers, air heaters, water heaters, and industrial furnaces.

Control boxes of this type are selected by matching the exact series and type designation, supply voltage, safety times (e.g., lockout time, pre-purge duration), flame detection method, and electrical base or plug pattern to the original component. Different series within the same brand are normally not interchangeable; always verify the original specifications before ordering. Mounting forms include box-type units with specific bases or plugs, so the physical configuration must also match.

Typical failures include lockout due to flame loss, ignition failure, or internal component malfunction, often indicated by the control box entering a fault state requiring manual reset. Symptoms may include the burner failing to start, shutting down during operation, or not responding to heat demand. Check for correct supply voltage, proper flame signal (ionisation or UV/IR), and integrity of wiring and safety contacts.
