Brahma 24223111 SM192N.2 control box

Brahma SM192N.2 is a microprocessor controller ("burner management system") designed for automatic ignition control, flame monitoring, and safe operation of two-stage atmospheric gas burners with an intermittent cycle. The device is suitable for burners with both natural draft (without fan) and forced air supply (with fan in the combustion circuit). Model SM192N.2 (art. 24223111) differs from SM191 by its ability to control two-stage burners, making it an ideal choice for equipment requiring two power levels (e.g., partial load and full load). In terms of timing parameters, this modification has a pre-purge and wait time of 1.5 seconds, which is suitable for most modern burners with a fast purge cycle. Application area includes: two-stage gas heating boilers (domestic and industrial); heat guns and hot air generators with two-stage modulation; air heaters, infrared heaters; Riello, Baltur, Weishaupt, Lamborghini two-stage burners. Main functions and features: Two-stage burner control: the controller provides sequential startup of the first and second power stages, allowing optimization of fuel consumption and maintaining comfortable temperature without frequent on/off cycles. Full automation of the combustion cycle: the unit independently performs the sequence: checking for false flame → pre-purge (1.5 s) → ignition on first stage → transition to full power (if needed) → combustion monitoring → safe shutdown upon flame loss. Ionization flame detection: flame detection via ionization electrode (rectification effect). Reaction time upon flame loss
