Boîtier de commande de la combustion Brahma BT111G, C00100369

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 in intermittent mode. It is widely used in hot air guns, burners and boilers from brands such as Lamborghini, Ecoflam, Giersch, Baltur, Riello, Master, Baxi, Beretta and others. Key feature: low‑voltage power supply (12 V DC) Unlike most burner controls (which operate from 220 V), the BT111G C00100369 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. Connection to 220 V mains is strictly prohibited and will damage the unit. Main functions and features Fully automatic combustion cycle – 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 EN 298. 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). Base included – Simplifies installation and provides IP40 protection. Technical specifications Parameter Value Model Brahma BT111G Article numbers C00100369, 246.124.184 Supply voltage 12 V DC Power consumption approx. 15 W Burner type Forced‑draught, single‑stage (gas/oil/combination) Operating mode Intermittent Pre‑purge time (tv/tp) 15 seconds (verify on housing label) Safety time (ts) 7 seconds (verify on housing label) Waiting time (tw) verify on housing label Response time on flame loss < 1 second Lockout reset Manual (Reset button) Base included Yes Enclosure protection class (with base) IP40 Operating temperature –20 °C to +70 °C Relative humidity max. 95% at 40 °C Dimensions (W×H×D) 90 × 85 × 65 mm Weight approx. 0.27 kg Important: Different versions of the BT111G may have different timing parameters. Before purchasing, always check the tv/tp and ts values printed on the unit’s housing against your burner’s requirements. For article number C00100369, typical values are 15 s and 7 s respectively. Do not confuse it with article number C00100275 (tv/tp = 1.5 s, ts = 5 s) – they are not interchangeable. Compatibility and replacement Compatible burners – Equipment from Lamborghini, Ecoflam, Giersch, Baltur, Riello, Master and other brands with single‑stage forced‑draught burners and parameters tv/tp = 15 s, ts = 7 s. Direct replacement – Article numbers C00100369 and 246.124.184 are identical. Connection – The base is included in the package. The connection diagram is printed on the housing. Installation and operation Mounting – In any position. The housing has standard dimensions, making it easy to replace obsolete controllers. To achieve IP40 protection, use the supplied base. 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 (C00100369) – 1 pc. Connection base – 1 pc. Quick installation guide. Order codes C00100369 (main article) 246.124.184 (alternative marking)
