Blowing pellets into the pellet storage room results in
an uneven dumping height of pellets stored inside. In
order to enable the pellet store to be emptied uni-
formly, the proportion of supply volume (assignment in
%) can be adjusted individually for each suction wand.

Purging and/or resetting suction wands
In the case of a shortage of pellets at one suction
wand, that wand will be blocked and a changeover to
the next suction wand occurs.
A blocked suction wand can be purged. A blocked
wand can also be re-enabled without prior purging. If
several wands have been preselected for purging,
these wands will be purged in sequence. Afterwards,
the system will be restarted in standard mode.
Manual purging will only commence if the pellet hopper
on the boiler is not full. Press the following buttons:
