Siemens Electromechanical burner control LME41.092C2

Siemens LME41.092C2 is an electromechanical burner control for atmospheric gas burners. It manages the start-up and control of 1- or 2-stage gas burners with intermittent operation. The unit features undervoltage detection, air pressure monitoring, remote reset signal, fault status indication, restart limitation, digital signal processing, and lockout on flame failure with manual reset. Flame monitoring is performed via an ionization electrode or a suitable flame sensor with auxiliary unit. This control box is not interchangeable across series.

When replacing a control of this type, match the exact series and type designation, supply voltage, pre-purge and safety times, and the flame detection method. Also verify the mechanical pattern—base or plug type—against the existing unit. Controls of this class are normally not interchangeable across different series, even within the same brand. A mismatched safety time or flame detection method is a safety issue, not a compatibility nuisance.
