If the room temperature or the outfeed temperature is
lower than the set value, the heating circuit pump will
be switched on.

Minimum flue gas
temperature 120°←
←←
←
Minimum target value for the flue gas temperature.
Lowest load point for continuous operation (if this
temperature is not reached, the output will be
increased).
Insulate the connection to the chimney!
Maximum flue gas
temperature 250°←
←←
←
Minimum target value for the flue gas temperature.
Top load point to ensure adequate efficiency (if this
temperature is exceeded, the output will be reduced).

In “Heating” status: if the difference between flue gas
temperature and boiler temperature falls below this
specified value, when the safety time has elapsed, the
controls go to “Fault” status  “Safety time elapsed
too low”.
In “Ignition” status: if the difference with the “Ignition
time max” does not exceed the value, the boiler goes
to “Fault”“Ignition attempt failed”
Min. flue g.-flue g.
temp. dif. 5°C
After heating, the flue gas temperature must have
risen by this value compared to the value before the
heating phase, to reach the status “Heating up”.

For emergency firewood operation: if the flue gas
temperature is below the specified value for 30
minutes, the ID fan and supply air fan are switched off.
Safety time 15m←

If during “Heating” status the shutdown conditions
(Boiler-flue gas temp.dif. or Shutdown excess O2) for
this period are not met, the boiler goes to “Insufficient
safety time elapsed” or “Safety time O2 too high”.

 Boiler in “heating up” status: Filling time for
combustion bowl. After this time has elapsed, the
boiler goes to “pre-heating” status
Factory settings: P2-10: 105s, P2-15: 95s, P2-20/25:
75s

 Boiler in “Heating up” status: Speed during the
heating up phase

 Boiler in “Pre-heating” status: Duration of the pre-
heating phase.
No pellets are fed in.
Fan without feed 45% ←
 Boiler in “Pre-heating” status: Speed during the pre-
heating phase
Ignition time max 15m ←
The boiler changes from “Ignition” status to “Heating”
status within the “Ignition time max” if the flue gas
temperature has reached the required value (“Min.
boiler-flue gas temp. dif.” parameter). Otherwise it
goes to the fault  “Ignition attempt failed!”.
