Troubleshooting
Fault indication/alarm
The burner has two types of fault indication: alarm and
warning.
In the event of an alarm, the burner stops. A red icon
is displayed in the display. If the screensaver is active,
the display will flash. The icon is displayed only after
the display has been touched. After the icon has been
touched, a new window is displayed with the cause and
additional information.
An alarm must be acknowledged before the burner can
be restarted.
A warning is displayed with a yellow icon in the display.
The burner does not stop and no acknowledgement is
required. Otherwise as above.
Alarm acknowledgement
When this window is displayed, the burner is locked on
account of an alarm. The alarm must be reset to allow
the burner to restart. This is done by touching the alarm
icon. A new window is then displayed with the cause of
the stoppage.

During measurement, the sensor must not be
connected to the burner.
Switch off the power to the burner and
detach the plug before cleaning or service
or before the burner is detached from the
boiler.
Troubleshooting
In the event of a problem, first check all the conditions
required for the burner to work:
• Is the burner receiving power?
• Are all control units, thermostats, etc. set correctly?
• Are all safety devices, overheating protection, hatch
switches, etc. in normal operating mode?
• Is the burner receiving pellets?
Look into the burner pipe if no flame has been
established. If there are unburned or slightly singed
pellets there, the most probable cause is an ignition
error.
If all the pellets have burned up, the most probable
cause is that there is a problem with the pellet supply.
If the cause of the problem is none of the above, all the
burner's functions must be checked.
If the burner is in alarm mode, i.e. the alarm indicator is
displayed in the display, it must be reset.
Follow the operation of the burner.
External fault sources
Common circumstances that give rise to operating
problems:
• the inclination of the feed auger from the horizontal
plane is not 40°±5°.
• the pellets do not meet the requirements under the
standard.
• draught >15 Pa.
• lack of draught damper.
• large area in flue.
• irregular fuel supply because the feed auger has not
travelled far enough, the pellet store is of poor quality
or there are a lot of crushed pellets in the store.
Checking the feed auger's capacity
A. Detach the quick coupler at the downpipe and
hold your hand over the quick coupler part that is
attached to the hose.
B. Connect the feed auger to a power point and let it
rotate through 3.5-4 revolutions.
C. The quick coupler part on the hose must be filled
with pellets. If this is not the case, check the
inclination of the feed auger and its insertion into the
pellet store.
