Brahma Control box DTMN11/G 37581000

The Brahma DTMN11/G control box is a microprocessor-based burner manager for automatic ignition and flame monitoring. It is designed for progressive (modulating) gas and liquid fuel burners with ionization flame detection. The unit operates in intermittent (cyclic) mode and is suitable for both forced draft and natural draft air supply. It incorporates a built-in ignition transformer and two safety contacts. The control box provides manual reset lockout with non-volatile memory and self-diagnostics. It fits Riello, Baltur, Weishaupt, and Lamborghini burners.

When selecting a replacement control box of this kind, match the exact series and type designation, supply voltage, safety times, pre-purge duration, flame detection method, and base or plug pattern to the existing sub-base. Verify the part number against the original component label before ordering. The unit mounts on a standard base and is wired according to the burner manufacturer's diagram. Using a variant with different timing or logic can reduce safety and is not allowed.

Typical failure symptoms include the burner shutting down with the control in lockout, shown by a protruding reset button. This occurs on loss of flame, ignition failure, or failure to prove the flame within the safety time. To recover, identify and remove the cause, then press the reset button manually. Check the flame sensor, ignition transformer, and wiring before deciding to replace the control.
