Siemens Burner control LME22.232C2

This Siemens control box is a burner control used for monitoring and controlling two-stage gas burners. It operates at a supply voltage of 230 V with a frequency range of 50–60 Hz and consumes 12 W. The safety time is 3 s, and it is rated for intermittent duty. The protection class is IP40, and the permissible ambient temperature is -20 to 60 °C. The device complies with EN 298.

Parts of this type are selected by exact series and type designation, supply voltage, safety times (pre-purge, ignition, flame proving), and the flame detection method (ionisation, UV, or IR). The base or plug pattern must match the burner wiring harness. Controls from different series, even within the same brand, are normally not interchangeable. Before ordering, compare the safety times and detector type with the replaced unit, because a mismatch creates a safety hazard.
