All display segments are out.
that the fuses of the control unit of the
burner are intact and the main switch
has been turned ON.
has the over-temperature protection
tripped?
Replace the defective fuse in the cont-
rol unit or turn ON the power by me-
ans of the main switch. Note! Discon-
nect the device from electricity supply
before replacing the fuse. The size of
fuses F1 and F2 is 4A/230 V.
If the cause of over-heating cannot be
determined with certainty, contact an
authorised technician. If the over-tem-
perature protection of the boiler has
tripped, put it back into operation by
pressing the RESET button. After this
switch the control unit OFF and then
back ON. Also check that the 3-phase
current is correctly connected.
The red operation indication is on.
The display reads:
ALARM PELLETS NO
.
The burner is requesting fuel, but
has not received it.
that there are pellets in the fuel sto-
rage.
Add pellets.
that the inclination of the drop pipe is
not too gentle.
Shake the drop tube and change the
inclination so that pellets will not get
stuck.
that the inclination of the external au-
ger is not too steep (max 45°) or feeding
of fuel has not stopped, because pellets
have been stuck in the silo.
Adjust the auger into a more gentle
angle and turn it back and forth a few
times so that the pellets come loose.
The feed opening of fuel must be loca-
ted in the middle of the fuel store (app-
lies to small week stores).
In case an alarm becomes active, this is indicated on the display of the control panel
with a red light and a text message. This facilitates troubleshooting, because the user
can see the cause of the problem. The alarm is acknowledged by selecting OFF on the
control unit. The cause of the alarm must always be determined and the problem re-
moved before the device is switched on again.
The following checks and remedies are described in such an order that the most pro-
bable cause of the problem is given first.

that the motor shaft rotates the auger
and the motor of the external auger
operates.
(In most cases the default setting of the
operating time of the external auger (30
seconds) is not long enough to bring suf-
ficient amount of pellets to the burner. If
the problem cannot be removed by me-
ans of the above checks and remedies,
the operating time of the external auger
may be too short. In such cases increase
the operating time (see page 15, menu 3
-> ”Auger external time”). However, the
operating time must not be so long that
pellets accumulate into the drop tube.)
If the motor does not rotate, disconnect
the power cable from the boiler and
connect it directly to a mains socket by
means of the additional cable provided.
If the motor has been over-heated due
to a blockage or for some other reason,
the over-temperature protection of the
motor may have been tripped. The mo-
tor will not start until it has been coo-
led down. Also check that there are no
blockages in the auger.
If there are problems with the motor,
contact an authorised technician.
The red operation indication is on

has the over-temperature protection

check the circulation pump.
If the cause of over-heating cannot be
determined with certainty, contact an
authorised technician. If the over-tem-
perature protection of the boiler has
tripped, put it back into operation by
pressing the RESET button. After this
switch the control unit OFF and then
back ON. Also check that the 3-phase
current is correctly connected.
The red operation indication is on
and the display reads:
CONTROL EL. IGNITION
or
CONTROL OPTICAL MONITOR
The cause of the problem is that
the optical flame monitoring of
the burner has not detected flame
during a certain period of time. No
fuel has entered into the combus-
tion head.
that the flame guard and/or the com-
bustion head is not full of ash and
the flame guard has not over-heated
or sooty.
Remove ash, clean the combustion
head from loose ash and wipe the
flame guard clean. If the flame guard
becomes easily sooty, the cause may
be incorrect settings or too low under-
pressure in the furnace. In such cases
call a technician.
