4. TECHNOLOGY AND SAFETY FUNCTIONS
The technological advances in your new combi stove are the result of
years of testing and practical experience� The practical advantages
of your pellet stove are convincing:
Operating comfort
The microprocessor-controlled combustion regulation optimises
the interaction of flue gas blower and screw using the current
combustion chamber temperature� This guarantees optimum
combustion and operating status�
All function can be regulated centrally using the integrated operating
unit� The intuitive graphic interface permits easy operation; all the
settings can be made quickly and simply�
Top efficiency - lowest emissions
A very great heat exchange surface together with optimum
combustion air control leads to excellent fuel utilisation�
Fine continuous pellet dosing in an optimised burner pot made of
high-quality grey cast iron leads to virtually complete combustion
with very good exhaust gas values - and this is guaranteed in every
operating phase�
Note
During operation, the flame noise, pellets dropping and actuation
of the electronic components are audible due to the automatic
control�
Pressure monitoring
The negative pressure in the combustion chamber is continuously
monitored during operation� Below a defined threshold, a correct
operation can not be guaranteed and the unit will switch off with the
fault message „NOT ENOUGH LOW PRESSURE" for safety reason�
Note
After the occurrence of the error message, maintenance or
cleaning work necessarily has to be carried out! If the error occurs
again, a safe operation is no longer guaranteed, the service must
be informed immediately�
Note
If the stove is used in a habitation together with a kitchen hood or
a ventilation (WC) it might happen that the built-in pressure switch
stops the stove� If using the hood make sure that an adequate
supply of air is ensured�
Low-temperature shutdown
The unit switches off if the stove cools below a minimum temperature�
This switch-off may occur if pellet ignition is delayed�
Electrical excess current protection
The stove has a main fuse (at the rear) to protect against excess
current�
Automatic cleaning cycle
The speed of the flue gas fan is increased every hour for a short
period to blow ash from the burn pot, increasing the operational
safety� The status indicator CLEAN appears on the display�
Only for stoves with turning grids:
Every 6 hours (interval adjustable) an additionally automatic big
cleaning cycle is performed� The stove stops, the automatic cleaning
tilts the grid and then re-ignites the stove� The status indicator BIG
CLEAN appears on the display continuously� The cleaning procedure
with tilting the grid is to convey ash and clinker from the burn pot
into the ash drawer�
Note
This additional function does not replace a manual cleaning
CLEANING
as described in
absolutely necessary to do regularly�
Note
Due to the turning grid there is a certain generation of noise during
the automatic cleaning cycle (START or BIG CLEAN)�
Component monitoring
All the electrical components used are continuously monitored
during operation� If a component is defective or can no longer be
actuated correctly, then operation is stopped and a warning or error
MANUAL TOUCH DISPLAY)
message is issued (see
Auger motor monitoring
Too long or wet pellets as well as pellets with too high dust content
BRIEF INFORMATION ON FUEL PELLETS
(see
so-called "auger jammers" in the auger channel� This may also
happen if the pellets accumulate in the burn pot and the backlog
reaches into the chute� The auger motor reacts in both cases with
an increased current consumption, which causes the error message:
DISCHARGE MOTOR BLOCKED
Please call the customer service immediately�
Power failure (during heating)
After a brief power failure, the operating functions that were set
before the power failure, continues� If the power failure lasts longer,
the stove goes to start phase if sufficient temperature or embers are
present� If the power failure lasts too long, the stove goes into the
stop phase� The flue gas fan continues to burn any pellet residues
(approximately 10 minutes)� Then it will restart automatically�
Power failure (during the initial stage)
After a brief power failure the boot process continues� If the power
failure lasts longer, the stove is in the stop phase� The flue gas fan
continues to burn any pellet residues (approximately 10 minutes)�
Then it will restart automatically�
