Siemens Control panel AZL23.00A9

This is an operator panel with a display for Siemens burner controls. It connects to the burner control via a BCI interface. It supports the LMV2, LMV3 and LME control series. The panel has IP54 ingress protection. Its net weight is 0.156 kg. It provides readout of operating parameters, diagnostics and settings.

Displays of this type are selected by matching the burner control series and the communication interface (typically BCI). They are mounted on the control panel front or burner enclosure and do not replace the safety control. Before ordering, verify the display model matches the control unit designation; a mismatched display may fail to communicate or show incorrect data. Replacements should be installed only after de-energising the system.

If a display of this type is mismatched, it may fail to communicate or show incorrect data. The display itself does not handle safety functions; its failure does not directly disable the burner, but it removes the operator's ability to read status and diagnose faults. Check that the display model matches the control unit's designation and that the communication link is intact.
