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 boiler hop-
per is not full.
