Note
Before restoring the backup data on the LMV27, the latter compares the burner identification
and product no. (ASN) with the burner identification and product no. (ASN) of the backup data
set. If the data accord, they are restored. If not, the restore process is aborted. In case of
abortion, or if an error occurs during the restore process, the display shows a negative value.
For error diagnostics, the cause of the error can be determined from the diagnostic code of
error message 137 (see Error code list). When the restore process is successfully completed,
value 0 appears on the display. The LMV27 is supplied with undefined burner identification. In
that case, the restore process from the AZL2 is possible without having to enter the burner
identification in the LMV27
Information Err C: 136 D: 1 (restore started) is displayed for a short moment
Caution!
On completion of the restore process, the sequence of functions and the parameter
settings must be checked.
