Brahma-22089901-MM191N.4-Steuergerät

Brahma MM191N.4 (part no. 22089901) is a fully solid-state microprocessor controller ("burner manager") that fully automates and ensures safe operation of gas burners. This device will become a reliable and efficient heart of your heating system. Purpose and application Brahma MM191N.4 is designed for atmospheric gas burners (both with and without a fan) and is equally effective for controlling both single-stage and two-stage burners in intermittent (cyclic) operation. The controller is a key component for a wide range of heat-generating equipment and is successfully used for automation of: Combined and heating boilers, Air heaters and hot air generators, Infrared heaters, Water heaters, Industrial furnaces, ovens and kitchen stoves. The control unit is compatible with burners of leading brands (Riello, Baltur, Weishaupt, Lamborghini and others) due to standardized time parameters and universal circuitry. Key features Reliable ionization flame control: Flame detection is based on its rectifying properties. Reaction time to flame loss is less than 1 second, which guarantees instant fuel shut-off and prevents emergency situations. Non-volatile lockout with manual reset: In any emergency situation (no flame, ignition failure, ionization circuit break), the controller locks out. Burner restart is possible only manually by pressing the Reset button on the housing after eliminating the cause of the malfunction. This eliminates the risk of spontaneous burner start-up and meets the highest safety class. Two independent safety contacts: A critically important safety function. The gas valve output is equipped with two independent
