Brahma Control box SM592N/S 36223331

The Brahma SM592N/S control box (SKU 36223331) is a microprocessor-based controller for automatic ignition, flame monitoring, and safe operation of atmospheric gas burners, supporting both single-stage and two-stage types. It operates in intermittent cycle and is suitable for burners with natural draught or forced air supply. The device uses ionization flame detection and includes combustion monitoring. It is a modern replacement for the SM592.2 model.

Control boxes of this type are selected by matching the series, type designation, supply voltage, safety and pre-purge times, and flame detection method. The base or plug pattern must match the burner wiring harness. Always verify the pre-purge time (tv), safety time (ts), and wait time (tw) indicated on the unit housing against the burner requirements. Parts of this kind are not interchangeable across series, even within the same brand.

When control boxes of this kind fail, the burner may fail to start, lock out during operation, or shut down unexpectedly. Common issues include failure to detect flame, ignition problems, or erratic behavior due to internal component failure. Check the flame sensor, wiring connections, and the control box's timing settings for faults.
