In case an alarm becomes active, this is indicated by the burner 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 burner stops in connection with an alarm. The cause of
the fault must be determined before switching the device on again. If an alarm is given often,
this may be due to incorrect adjustments/settings. When the red light blinks, the burner dis-
play shows a warning message, for example, about the fact that it is time to empty the ash box.
However, the burner functions normally. Acknowledge by pressing the C button. In order to
check and service the burner, it is first necessary to cut the voltage supply and detach the burn-
er connection wires before removing the burner from the boiler. After this, the burner cover
can be detached and the inspection of the flame detection sensor or other component can be
carried out.
ALARMS AND TROUBLESHOOTING
Alarm message / Cause Check Procedure
Alarm flame detection
The flame detection sensor has not de-
tected any flames for 10 minutes with
the burner in Power mode. The level
switches have requested more pellets,
which means that pellets have arrived
at the burner head. .
1. Operation and cleanliness of the fla-
me detection sensor.
2. Blower operation
1. See "Alarm cold start" (para-
graph 2).
2. Go to the Testing menu and
turn the blower on. Make sure
that the blower works.
If the flame detection sensor be-
comes often sooty or overhea-
ted, this may be due to faulty
adjustments or insufficient va-
cuum in the furnace. In these ca-
ses, contact the installer.
Alarm hot start
After a hot start, the flame detection
sensor has not detected any flames for
10 minutes. The embers have all burnt
and the burner does not use any igni-
tion resistance when performing a hot
start. After cleaning the burner head,
the boiler water temperature may be
within 8ºC of the set temperature. In
this case, the burner will try to perform
a hot start. Since there are no embers,
the alarm will be given.
1. Operation and cleanliness of the fla-
me detection sensor.
2. Ember maintenance time (Power
menu)
1. Check the flame detection
system as specified above.
2. Check the embers while being
in Maintain mode. Excessive
draught may burn the embers
completely. In this case, reduce
the draught and the time of the
Ember Maintenance setting.
If the alarm has been given af-
ter cleaning the burner head,
increase the set temperature of
boiler water temporarily in order
for the burner to be able to per-
form a cold start.
Alarm residual oxygen
Residual oxygen has been under 4.5%
for 2 min, which has caused poor com-
bustion. The automatic power increase
of the blower has not been enough.
1. Are the air vents of the burner head
open?
2. Is the blower functioning well? Has
the blower been correctly adjusted?
1. Clean the burner head and
open the air vents.
2. Check the operation and po-
wer of the blower.
NOTE! If residual oxygen is set
to Off mode, no alarm is given
even if the residual oxygen value
is displayed on the screen.
Alarm message / Cause Check Procedure
The burner has stopped and the display
is dark.
Voltage is no longer supplied to the
burner.
1. Burner overheat protection.
2. Voltage supply fuse.
3. Glass tube fuses of the burner
card and connection of the display
panel.
1. Find out the cause of overheating
and confirm receipt of the overheat
protection.
2. Change the fuse. If the fuse conti-
nues to blow, contact an electrician.
3. The inspection may be carried out
by an electrician. Take out the display
panel and check the glass tube fu-
ses of the controller card. Check the
display panel connection.
Alarm cold start
The flame detection sensor has not de-
tected any flames in connection with a
cold start. The alarm is given 10 min af-
ter the end of the cold start.
1. Are there pellets in the burner
head?
2. Operation and cleanliness of the
flame detection sensor
3. Ignition resistance
1. If the burner head does not con-
tain pellets but the upper connecti-
on of the burner does, try to reignite.
Make sure that the burner head re-
ceives pellets.
2. The operation of the flame detec-
tion sensor can be checked by ref-
lecting light on it. How the sensor
reacts to it can be followed from the
Burner Adjustments menu. The flame
detection sensor may have become
dirty due to weak draught. This pre-
vents the sensor from recognising
flames. See "Inspection and Main-
tenance".
3. Go to the Testing menu and turn
the blower and the ignition resistan-
ce on. Make sure that the resistance
heats up and ignites the pellets.
