Note
With the warm settings, the burner is started up after pressing the Info button. Air-fuel ratio
control can now be accurately set while the flame is present. When traveling along the
precalculated curve to high-fire point P9, all intermediate curvepoints (P2...P8) must be set.
Automatic operation is released when – after reaching P9 – the curve settings are quit by
pressing ESC. If the curve settings are aborted earlier (ESC or shutdown due to fault),
prevention of startup OFF UPr continues to be active until all points are set.
If required, the gas pressure can be set at the high-fire point. In case the gas pressure is
changed, all points must be checked by traveling along the curve downward and – if required
– readjusted.

Note
If, during the time the curve is parameterized, an error occurs which leads to safety shutdown,
parameterization of the curve is quit.
