5. 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
All functions can be regulated using the integrated touch display�
The user-friendly interface permits extremely easy operation�
Top efficiency - lowest emissions
All processes in the stove are fully automated� The parameters
Q
Air control
Q
Temperature monitoring
Q
Pellet dosing
are continuously optimised� This guarantees optimum combustion�
The result are low consumption and very good exhaust gas values
that even undercut the legally permitted limits�
Note
Due to the automated control, you may hear flame fluttering,
falling pellets and sounds from the activation of the electronic
components during operation�
DAR - Dynamic Air Regulation
A differential pressure sensor in the supply air system measures the
air flow� The fan speed is adjusted automatically and guarantees
optimum combustion�
The air pipe of an external supply air pipe can also be monitored in
this way�
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
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 as
described in CLEANING and MAINTENANCE, as this is 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
message is issued (see MANUAL TOUCH DISPLAY)�
Auger motor monitoring
Too long or wet pellets as well as pellets with too high dust content
(see BRIEF INFORMATION ON FUEL PELLETS) can cause 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� The stove will be stopped� 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�
