Steuergerät für die Verbrennung Brahma BT211G, C00100289

Brahma BT211G (art. C00100289 / 246.124.143) is a microprocessor-based controller (“burner management unit”) from the EUROBOX series, designed for automatic ignition control, flame monitoring and safe operation of forced‑draught (fan‑assisted) burners in intermittent (cyclic) mode. This control unit is suitable for both single‑stage and two‑stage burners running on gas, oil or combination fuels. Applications include: Industrial and domestic heating boilers. Hot air guns and warm air generators. Air heaters and process furnaces. Equipment with burners from leading brands: Riello, Baltur, Weishaupt, Lamborghini and others. Key feature: low‑voltage power supply (24 V DC) Unlike most burner controls that operate from 220 V, the BT211G C00100289 is powered by a 24 V DC power supply. This makes it an ideal solution for systems with low‑voltage control circuits, stand‑alone installations, and for directly replacing obsolete low‑voltage controllers. Connection to 220 V mains is strictly prohibited and will damage the unit. Main functions and features Fully automatic combustion cycle – The unit independently manages the sequence: false flame check → pre‑purge (10 seconds) → ignition → flame monitoring → safe shutdown on flame loss. Ionisation flame control – Flame detection via an ionisation electrode based on the rectifying properties of the flame. Response time on flame loss is less than 1 second, meeting strict safety standards. Manual lockout reset – Under any abnormal condition (no flame, open ionisation circuit, ignition failure) the unit goes into lockout. 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 while a fault persists. Built‑in high‑voltage ignition transformer – Simplifies installation and reduces the number of external components. Compact and robust housing – Made of heat‑resistant plastic with IP40 protection, protecting the electronics from dust and accidental water splashes. High reliability – Controller service life: more than 250,000 switching cycles. Standards compliance – The device is certified according to European directives and meets standards EN298:2003 (automatic burner control systems for gas burners), EN676:2003 (forced‑draught gas burners), DIN 4788 and EN230:2005 (oil burners).

Direct replacement – Article numbers C00100289 and 246.124.143 are identical. Before purchasing, ensure that your burner’s timing parameters match the unit’s settings (tv/tp = 10 s, ts = 5 s, tw = 10 s). Accessories – A connection base is not included and must be purchased separately. The connection diagram is printed on the device housing. Installation and operation Mounting – The device can be mounted in any position. The housing has standard dimensions, making it easy to replace obsolete controllers. IP40 protection allows the unit to be used in dry and moderately dusty environments. Wiring – Strictly observe correct connection of live and neutral wires. Disconnect power before starting work. Connection to any voltage other than 24 V DC is strictly prohibited. Initial start‑up – Before start‑up, ensure the combustion chamber has been purged, the ionisation electrode is correctly positioned and provides a stable flame signal. Lockout reset – When a safety lockout occurs, find and eliminate the cause, then press the Reset button on the housing. Maintenance – Periodically check the condition of the contacts, wiring integrity, and the cleanliness and position of the ionisation electrode. Operating mode – The unit is designed for intermittent operation. To maximise service life and safety, the system must be forced to stop at least once every 24 hours. Advantages over alternatives Low‑voltage power supply (24 V DC) – Ideal solution for systems with low‑voltage control circuits, stand‑alone installations and replacing obsolete controllers. Optimal timing parameters (10/5/10 s) – Perfect balance between combustion chamber purge time and start‑up speed. Reliability – Service life of more than 250,000 cycles, proven by the manufacturer. Safety – Manual lockout reset + non‑volatile fault memory meet the highest EN298 standards. Versatility – Suitable for gas, oil and combination burners, both single‑stage and two‑stage. Italian quality – High‑grade components, strict production control. Package contents Brahma BT211G burner control unit (art. C00100289) – 1 pc.
