The LMV2x complete programming must be performed on units that has never been set before or reset units (e.g. spare parts).
The programming procedure is performed by setting the following main parameters:
1 if LMV.. is a spare part, insert burner ID (parameter 113) at least 4 digit.
2 type of fuel train (parameter "201")
3 air/fuel ratio curvepoints (Block "400")
4 maximum load percentage (parameter "546")
5 minimum load percentage (parameter "545")
CAUTION: if an error message as "Loc.." appears when the unit is turned to on for the first time, press ENTER (InFo) until
the "Reset" message apperas. After few seconds, the message "OffUpr" will be displayed.
This message shows that the unit has not been programmed before or that the operating mode (fuel train) is not set yet or that the unit
