Brahma Combustion control unit MM192N.2 22283721

The Brahma MM192N.2 combustion control unit (SKU 22283721) is an automatic device for managing ignition and combustion in gas burners, boilers, and heat generators. It operates at 230 V supply voltage, uses ionization flame detection, and has a protection class of IP40. The unit features microprocessor control, a built-in high-voltage ignition transformer, and LED fault diagnosis. It is suitable for low and medium power gas burners with one or two electrodes. Order numbers include 22283721 and 246.124.234.

When selecting a replacement control box of this type, verify the exact model designation, supply voltage, safety and pre-purge times, and flame detection method (ionization for gas). The mounting form (DIN rail or screw) and base/plug pattern must match the burner wiring. Controls from different series within the same brand are not interchangeable; using incorrect safety times creates a hazard. Always cross-reference the new part against the burner manufacturer's specification.

Typical failures of combustion control units include lockout due to flame detection issues, ignition failure, or internal component malfunction. Symptoms may include the burner failing to start, repeated lockouts, or erratic operation. Check the flame sensor, ignition transformer, and wiring connections. LED fault codes can help diagnose specific issues.
