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.
