Brahma Control box CM381N.4 30030692

The Brahma CM381N.4 control box (SKU 30030692) is a microprocessor-based flame safeguard for atmospheric gas burners with fans, operating in intermittent mode. It supports single-stage and two-stage burners and uses ionization flame detection. The unit features manual reset safety lockout and two independent safety contacts for gas valve control. It is compatible with burners from Riello, Baltur, Weishaupt, and Lamborghini.

Control boxes of this type are selected by matching the exact series and type designation, supply voltage, safety and pre-purge times, and flame detection method (ionisation, UV, or IR). The base pattern or plug type must match the existing wiring. Even within the same brand, different series are not interchangeable; confirm all parameters against the original part specification before ordering.

Typical failures include lockout due to flame loss, ignition failure, or ionization circuit break, requiring manual reset after the cause is eliminated. Symptoms may include the burner failing to start, repeated lockouts, or immediate shutdown after flame establishment. Check the ionization electrode, wiring, and gas valve contacts for faults.
