6. 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
The automatic control system means that during operation, the
flame noise, pellets dropping and actuation of the electronic
components permissible for living spaces are audible�

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 room together with a kitchen hood it might
happen that the built-in pressure switch stops the stove� If using
the hood make sure make sure that an adequate supply of air is
ensured�

Overheating

A high temperature limiter (OTB) switches the stove off automatically
on overheating� The message „STOVE OVERHEATED" appears�
Please take the measures in the manner described in „WARNING
AND ERROR MESSAGES"� The stove is ready for operation again
after acknowledging the error message at the internal unit�
Note
Maintenance and cleaning work must be performed if overheating
occurs! If this error recurs, operation without danger is no longer
guaranteed; notify customer service immediately�

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 CLEANING appears on the display�
This additional function does not replace a manual cleaning as
described in CLEANING and MAINTENANCE, as this is absolutely
necessary to do regularly�

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 WARNING AND ERROR MESSAGES)�

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�
