Beretta Control board R10030433 SP000018

This Beretta control board, model R10030433, is a burner control (flame safeguard) for modern wall-hung boilers. It fits Beretta Ciao N 24-28 CAI, 24-28 CSI, and 24 CSI Nord. The board manages the complete ignition and safety sequence: it starts the fan for pre-purge, checks the air pressure switch, energises the ignition transformer, opens the gas valve, and confirms the flame signal within the safety time. If the flame is not proved, it locks out and requires a manual reset. Its electrical connection and mounting pattern are model-specific; the SKU is SP000018.

Control boards of this type are selected by exact boiler series designation, supply voltage, safety and pre-purge times, and the flame detection method (typically ionisation in gas boilers). The electrical connector pattern and mounting arrangement are model-specific and must be compared with the original board. Even within the same brand, boards are generally not interchangeable across different series; using a board with mismatched safety times creates a safety hazard, not just a functional issue. When replacing, verify the original part number or the boiler's model designation to ensure a correct match.
