Siemens Burner control LME22.131C2

This Siemens LME22.131C2 burner control box manages start-up and operation of 2-stage gas or dual-fuel burners with intermittent operation. It operates on a 230 V AC supply and provides a safety time of 3 s, pre-purge time of 7 s, and pre-ignition time of 3 s. The control monitors pressure switches and the flame signal, and drives actuators with opening and closing times of 12 s each. It features a waiting time of 2.5 s, an interval between ignitions of 8 s, and an air pressure switch setting time of 65 s.

Replacement burner controls of this type are selected by the exact series and type designation, supply voltage, safety time, pre-purge time, flame detection method, and base or plug pattern. Controls are not interchangeable across series even within the same brand. Always confirm these parameters against the original control before ordering.
