Brahma VM44G combustion control unit (art. 37200760) is a microprocessor burner manager designed for full automation of ignition, flame monitoring and safe operation of forced draught gas burners in intermittent (cyclic) mode. The device complies with European standard EN 298, ensuring stable combustion, efficient fuel burning and a high level of safety for low and medium power burners. Main technical specifications Parameter Value Model Brahma VM44G Part numbers 37200760, 246.124.255 Supply voltage 220–240 V, 50/60 Hz Power consumption 30 VA Burner type Forced draught (with fan), single-stage or two-stage Combustion method Forced draught burners Fuel type Gas Operating mode Intermittent Pre-purge time (Tv) 30 seconds Safety time (Ts) 2 seconds Flame monitoring Ionization electrode Operating temperature from -10°C to +60°C Protection class IP40 Weight ~0.4 kg Service life > 250,000 cycles Key functions and features Ionization flame monitoring – reliable and instantaneous flame detection. Non-volatile lockout – in an abnormal situation, the device locks and retains this state even when power is disconnected, preventing spontaneous start-up. Manual reset – restart after a lockout is only possible via the button on the housing, which is a key safety measure. Air damper control – support for various types of servos for precise flame modulation. Two independent safety contacts – redundant gas valve control circuits for maximum reliability. Diagnostics and indication – possibility to connect a signal lamp for lockout indication and data transmission about the operating cycle via a special cable. High reliability – service life of electronic components over 250,000 cycles.
