產(chǎn)地：德國 | | ⊙ 產(chǎn)品詳細說明 | | | 產(chǎn)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). -
Automatic forced draft burners for gaseous fuels to EN 676 -
Gas burner controls to EN 298 -
Undervoltage detection -
Air pressure supervision with functional check of the air pressure monitor during startup and operation -
Electrical remote reset facility -
