Brahma 37100030 CM11F control box

Brahma CM11F (art. 37100030) is a reliable microprocessor controller for your gas equipment, providing a complete control cycle from ignition to safety shutdown. It is ideally suited for two‑stage atmospheric gas burners and works equally well with forced air supply (with a fan) or without. Thanks to its versatility and high safety class, this “burner control unit” has become a key component for a wide range of heat‑generating equipment. Heating systems: Gas and combination boilers for private homes and industrial boiler houses. Climate control equipment: Hot air guns, warm air generators, infrared heaters and radiant tube heaters. Water heating and process equipment: Water heaters, combi steamers, ovens, cooktops and industrial furnaces. Compatibility: The controller is suitable for burners from leading brands: Riello, Weishaupt, Giersch, Baltur, Lamborghini and many others. Main features of Brahma CM11F Two‑stage burner control – This is the device’s main function. It enables the burner to operate at two power levels (partial and full load), significantly saving fuel and reducing the number of starts and stops. Manual lockout reset – A key safety feature. In an abnormal situation (e.g., flame loss) the device locks out. To restart, you must manually press the Reset button on the housing after eliminating the fault. This eliminates the risk of unintentional burner start‑up. Instant ionisation flame monitoring – Flame detection is based on its rectifying properties. On flame loss, the controller reacts instantly – in less than 1 second – and immediately shuts off the gas supply. Fully automatic combustion cycle – The device completely manages the entire process: checks for false flame, performs pre‑purge (1.5 s), controls ignition and the fan, and then monitors combustion stability. Robust impact‑resistant housing – Made of flame‑retardant plastic, effectively protecting the electronics from external influences. Mounting in any position is possible. Reliability and durability – Service life rated for more than 250,000 switching cycles. Technical specifications Parameter Value Model Brahma CM11F Article numbers 37100030, 246.124.205 Supply voltage 230 V AC, 50/60 Hz (110‑120 V version available) Burner type Atmospheric, two‑stage Operating mode Intermittent (must be stopped once every 24 hours) Pre‑purge time (tv/tp) 1.5 seconds Safety time (ts) 10 seconds Waiting time (tw) 1.5 seconds Response time on flame loss 5 µA for reliable operation). Lockout reset – When a safety lockout occurs (red LED lit), find and eliminate the cause, then manually press the Reset button on the housing. Maintenance – Periodically check the condition of the ionisation electrode, its insulation and the gap relative to the burner. Contamination can lead to false trips. Advantages over alternatives Specialisation for two‑stage burners – Provides flexible power control for fuel savings. Highest safety class – Manual lockout reset eliminates automatic restart after a fault. High reliability – Italian quality of assembly and components guarantees a long service life (more than 250,000 cycles).
