Unidad de control de combustión Brahma BT111G, C00100275

Brahma BT111G is a microprocessor-based controller (“burner management unit”) designed for automatic ignition control, flame monitoring and safe operation of forced‑draught gas, oil and combination burners with single‑stage regulation. The device operates in intermittent mode and is widely used in hot air guns, burners from Lamborghini, Ecoflam, Giersch, Baltur, Riello and other equipment. Key feature: low‑voltage power supply (12 V DC) Unlike most burner controls that operate from 220 V, the BT111G is powered by 12 V direct current. This makes it an ideal choice for systems with low‑voltage control circuits, mobile or stand‑alone installations. Main functions and features Fully automatic combustion cycle – The unit manages the sequence: false flame check → pre‑purge → ignition → flame monitoring → safe shutdown on flame loss. Ionisation flame control – Instant flame detection via an ionisation electrode. Response time on flame loss is less than 1 second, meeting the highest safety standards. Manual lockout reset – In the event of an abnormal condition (no flame, ignition failure), the unit goes into a safe state. Restart is only possible manually by pressing the Reset button on the housing after the cause has been eliminated. This prevents the burner from starting unintentionally. Built‑in high‑voltage ignition transformer – No external ignition unit required. Automatic self‑check at each start‑up – Diagnostics of key circuits. Lockout alarm output – Allows connection of external signalling (lamp, buzzer).

Direct replacement – Article numbers C00100275 and 246.124.149 are identical. Connection – A base (Microflat type or similar, purchased separately) is required. The connection diagram is printed on the housing. Installation and operation Mounting – In any position. Due to IP00 protection class, it is recommended to install the unit in a protective enclosure/cabinet. Wiring – Strictly observe polarity and the 12 V DC voltage level. Incorrect connection to 220 V will damage the unit. Lockout reset – After eliminating the fault, press the Reset button. Operating mode – The unit is designed for intermittent operation (must be stopped at least once every 24 hours). Package contents Brahma BT111G control unit (C00100275) – 1 pc.
