  產品介紹

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).
