Siemens LGB21.330A27 burner controller
Burner controls for the supervision of 1- or 2-stage gas or gas / oil burners of small to medium capacity (typically up to 350 kW), with or without fan, in intermittent operation. The LGB... and this Data Sheet are intended for use by OEMs which integrate the burner controls in their products.
The LGB... burner controls are used for the startup and supervision of 1- or 2-stage gas

In connection with the respective adapters, the LGB... burner controls replace their predecessor types LFI7... and LFM1... (also refer to Replacement types under Ordering).
