Brahma Control box 18049001

The Brahma 18049001 is a microprocessor-based control box for single-stage forced-draft liquid fuel burners, operating in intermittent (cyclic) mode. It has a pre-purge time of 20 seconds and a safety time of 5 seconds, with a flame loss reaction time of less than 1 second. It supports flame detection via ionisation, UV, or IR methods and includes two safety contacts. It is compatible with burners from Riello, Baltur, Weishaupt, and Lamborghini, and is suitable for oil burners with a maximum throughput of 30 kg/h.

When selecting a control box of this type, verify that the supply voltage, safety time, pre-purge time, and flame detection method match the original. Ensure the wiring base or plug connector is compatible, as controls are not interchangeable across different series. Check the burner's specifications and the appliance manual to confirm the required parameters.

Common failure modes include failure to ignite, lockout after the safety time, or immediate shutdown upon flame loss. The equipment may show a fault code or fail to start. Check the flame detector, wiring connections, and the control box's internal fuse or relay for issues.
