During storage, the LMV51... sorts the curvepoints based on rising output. This means
that you can enter the curvepoints in any order you like as long as the output was
correctly set.
Proceed in this way point by point until the minimum output is reached. After storage of
the minimum output point, leave the curve setting.

The curvepoints can be changed during burner off periods (Phase 12) or during burner
operation (Phase 60).
To change an existing curve, select the curvepoint in «Point» mode. You are now able
to change the point, or to cancel it.
