Skrzynka sterująca Brahma 37010010 FM11

Brahma FM11 control unit is designed for intermittent‑cycle atmospheric gas burners (without a fan). The FM11 performs a full control cycle: from pre‑purge and ignition to continuous flame monitoring and safety shutdown. This device is an ideal choice for gas equipment where fan control is not required, including: Gas and combination boilers (especially Sime brand: RX 19, RX 26, RX 37, RX 48, RX 55); Heating and water heating boilers; Water heaters and air heaters; Infrared (IR) heaters; Modules and furnaces with atmospheric burners. Compatibility: It is a direct OEM equivalent for Sime boilers with part numbers 6178830 and 6178834. Main functions and features Despite its apparent simplicity, this control unit is responsible for several critically important functions that ensure the reliability and safety of boiler equipment. Basic flame control with instant response – Flame control in this controller is based on the ionisation effect. If the burner flame goes out, the automatic system reacts to the loss in less than 1 second, immediately shutting off the gas supply. Dual safety circuit – Two independent safety contacts are provided for gas valve control. This redundancy guarantees that the system will close reliably in the event of any fault. Manual reset – A feature of the FM11 series automatics is that after a safety shutdown (e.g. due to flame loss), the unit can only be restarted manually by pressing the reset button on its housing. Built‑in ignition transformer – The device is equipped with a built‑in high‑efficiency 20 kV ignition unit. This simplifies installation because there is no need to purchase and install a separate ignition module. Standard timing cycles – The ignition programme provides a pre‑purge time of 1.5 seconds and a safety time of 10 seconds. These are the standard and most common parameters for gas boilers.

Compatibility and replacement Direct replacement for Sime boilers – Brahma FM11 (37010010) is a direct OEM equivalent for Sime boilers with part numbers 6178830 and 6178834. Wide compatibility – It is also successfully used in burners of other popular brands, including Riello, Weishaupt, Giersch, Viessmann, Lamborghini. Accessories – A Microflat‑type base is required for connection (purchased separately). Direct replacement – Article numbers 37010010 and 246.124.071 are identical. Installation and operation Mounting – The FM11 unit is intended for installation in dry, well‑ventilated locations. Protection class IP00 requires the device to be placed in a protective control cabinet to prevent dust and moisture ingress. The unit can be mounted in any position. Wiring – The connection diagram is printed on the housing. Strictly follow the correct connection of live and neutral wires. Self‑check and start‑up – Each time the burner control is switched on, it performs a self‑test of the flame signal amplifier. Lockout reset – When a safety lockout occurs, find and eliminate the cause (check gas supply, ionisation electrode, etc.), then manually press the reset button on the housing to restart. Advantages over alternatives Proven reliability – Simple, trouble‑free design proven by many years of operation in millions of boilers worldwide. Easy replacement – Ideal for replacing obsolete or failed control units, especially in Sime boilers. Safety – The use of two independent safety contacts and manual lockout reset meets the highest safety standards for gas equipment.
