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

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.

Overheating

A safety temperature limiter (STL) switches the stove off automatically on 

overheating. Once the stove has cooled, the STB at the stove rear must be 

unlocked manually (pressed). 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.

Only for stoves with turning grids:

Every 6 hours (interval adjustable) an additionally automatic cleaning cycle 

is performed. The stove stops, the automatic cleaning tilts the grid and then 

re-ignites the stove. The status indicator CLEANING 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. 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.
