Boiler functionality
If the boiler is turned on ( ), it will be in standby
mode ([Ready] mode). If there is a request from a
connected consumer (for example, buffer, heating
circuit or hot water tank), the heating mode starts auto-
matically. Once the heat is delivered to the consumer,
a yellow line appears beside the flow temperature and
the symbol of the consumer in the overview.
If there is no heat demand, the heating operation is
completed upon burnout. The operating condition
changes to [Ember burnout] and then back to standby.
Boiler de-ashing takes place automatically within an
adjustable interval. See chapter 6.2.2.3 "
Boiler de-
ashing interval". De-ashing can also be disabled for a
time, e.g. to prevent the boiler from de-ashing at night.
See chapter 6.2.2.4 "
Setting the idle time for heat
exchanger de-ashing".
The control system issues a reminder to empty the ash
box after a set quantity of fuel has been consumed. If
the ash box is only partially full, this quantity can be
increased. See chapter 6.2.2.5 "
Empty ash box after".
