The LGB... burner controls are used for the startup and supervision of single- or 2-stage gas or gas / oil burners in intermittent operation. Depending on the type of burner control used, the flame is supervised either by an ionization probe, a blue-flame detector QRC1... for forced draft gas / oil burners, or a UV detector QRA... (with auxiliary unit AGQ1...A27).
In connection with the respective adapters, the LGB... burner controls replace their predecessor types LFI7... and LFM1... (also refer to ?Replacement types under Ordering).
