WARM-UP PRO indication of re-
maining duration in minutes
The furnace begins to throw in pellets, the ig-
niter element is started, the ignition is moni-
tored (after correctly warming up, the furnace
switches to the heating programme H). The
warm-up programme takes 15 minutes. The
display counts down by minutes.
AI

WARM-UP PROGRAMME IN + display in
minutes
(blinks in alternation with G OFF). The fur-
nace is still in G OFF.
However, the furnace has registered that the
I/O button was pressed again. The furnace in-
dicates that it will automatically resume oper-
ation in x minutes (after G OFF elapses).
AI 11 = warm-up in 11 minutes.

HEATING PRO display of ad-
justed output in kW
The furnace is in heating mode. H 6.0 = heat-
ing programme 6 kW.
R.M
2.0
Internal modulation on flue gas side + display
of output in kW
The flue gas temperature "TR" was
exceeded. The furnace is run at the
lowest output (2 kW) via the internal
control. Once the temperature low-
ers sufficiently, the furnace returns to
the heating programme H.
The temperature on the air volume
sensor was exceeded. The furnace
regulates to the lowest output (2 kW)
Once the temperature lowers suffi-
ciently, the furnace returns to the
heating programme H.
R
120
CLEANING PROGRAMME R + indication of
remaining duration in seconds
An automatic cleaning cycle of 120 seconds
is started after each hour of continuous oper-
ation in heating programme H. Pellet convey-
ance is reduced and the fan speed is in-
creased in order to reduce the pellet volume
in the burner pot and to centrifuge the flue
ash out of the burner pot.
G
OFF
FAN STOP DELAY (= furnace shut-down.
Duration 15 minutes)
The furnace shuts down. The fan runs for 15
more minutes in order to fully burn away the
remaining pellets and to remove the heating
gases. Attention: the furnace only actually
goes into Stand-By after G OFF when G OFF
does not blink in alternation with HE OFF or
TW OFF. In other cases, the furnace can /
will be automatically restarted after G OFF.

possible with external controller)
The furnace is shut down via an external con-
troller (via the ON/OFF input or BUS)
OF
…
Processing remaining time: the furnace was
shut down via an external controller (via the
ON/OFF input). The remaining time is dis-
played as a countdown in minutes, in alterna-
tion with the current operating state. This
function is only possible if the remaining time
was set to >0 (menu level 2).
PL
OPEN
Pellet drawer open.
The pivoting lid of the pellet container is
open. If it is opened for longer than 3 minutes
without interruption during furnace operation
(mode = A, H, HM, R.M, HE, G OFF), the fur-
nace goes into fault (PL, Err).
FT
OPEN
Combustion chamber door open.
The combustion chamber door is open. If the
combustion chamber door is opened for
longer than 1 minute without interruption dur-
ing furnace operation (mode = A, H, HM,
R.M, HE, G OFF), the furnace goes into fault
(FT, Err).
Only open combustion chamber door when
the furnace is not operating!
