Parameter Backups / Restores

Both the LME7 burner control and PME7 program module contain one parameter set. The parameter
set in the LME7 burner control is always the one that is used for burner operation. The parameter set in
the PME7 program module is simply a backup parameter set. At any time, these two parameter sets can
be synchronized with a parameter backup or a parameter restore.
Parameter backup – Overwriting the PME7 parameter set with the LME7 parameter set
Parameter restore – Overwriting the LME7 parameter set with the PME7 parameter set
The following procedures can be used to perform parameter backups or parameter restores.
Parameter Backup (LME7 -> PME7) Using the LME7 Built-in Display
1. Press and hold the + and - buttons on the LME7 together for approximately one second. "PrC"
will be displayed briefly, then the display will show "rSt".
2. Press the + or - button to toggle to "bAC".
3. Press and hold the info button until the word "run" is displayed, then release.
4. The LME7 will alternately display "bAC" and "End" once the parameter backup is complete.
5. Press the info button to return to the normal display.
Parameter Restore (PME7 -> LME7) Using the LME7 Built-in Display
Use to overwrite the parameters in the LME7 with those previously saved in the PME7.

will be displayed briefly, then the display will show "rSt".
2. Press and hold the info button until the word "run" is displayed, then release.
3. The LME7 will alternately display "rSt" and "End" once the parameter restore is complete.
4. Press the info button to return to the normal display.
Parameter Backup (LME7 -> PME7) Using the AZL23 Display Unit
