Brahma Combustion control unit VM44G 37200752

The Brahma VM44G (part number 37200752) is a microprocessor burner control unit for forced-draught gas burners. It runs on 220–240 V and is intended for single-stage or two-stage burners operating in intermittent mode. The control unit provides a 30-second pre-purge and a 2-second safety time, and monitors the flame with an ionization electrode. If an abnormal condition occurs, it goes into a non-volatile lockout and can only be reset manually. It is equipped with two independent safety contacts and supports connection of air dampers. The unit has an IP40 protection rating, weighs 0.4 kg, complies with EN 298, and is rated for 250,000 cycles under maximum load.

For a replacement of this kind of control box, match the exact type designation, supply voltage, pre-purge and safety times, and flame detection method. Even within the same brand, a different series is usually not interchangeable; a mismatch in safety time is a safety hazard rather than a simple functional issue. The physical base pattern or plug configuration must match the burner's wiring base. Confirm the part number with the burner or boiler manufacturer's specification before installation.
