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 anionization 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).
