5 - Safety temperature limiter (STB) has
tripped
Due to excessively low energy take-up, the boiler tem-
perature may rise above ~90°C. In this case, the inte-
grated safety temperature limiter (STL) trips and
initiates a rapid shut-down of the boiler.
Information on the STB (unlocking on release)
Feeding too much fuel (log wood), the boiler
could provide too little energy.
–
Check the buffer cylinder temperature before refil-
ling; only supply as much fuel as required.
Power failure during operation
–
If this occurs frequently: Contact qualified per-
sonnel (cause may be due a defect in the electrical
power line/distributor)
Operating pressure in the heating system too low
–
Too low pressure (possibly air in the line system)
can be the reason for poor removal of the heat
energy. Check the pressure, bleed the system.
18 - Combustion stopped
This message appears in the boiler operating mode
Log wood
when the combustion process had to be
stopped due to multiple temperature limit violations.
Supply of too much fuel (log wood), although no
energy reduction was provided
–
Check the buffer cylinder temperature before igni-
ting; only supply as much fuel as required.
Fault in circulation pump (return booster pump,
buffer cylinder charging pump) or heating circuit
mixing valve
–
Check the pumps/ mixers by means of the screen
Output test
–
Pump /mixing valve is not electrically connected
–
Air in the pump/ line - bleed
Operating pressure in the heating system too low
–
Too low pressure (possibly air in the line system)
can be the reason for poor removal of the heat
energy. Check the pressure, bleed the system.
21 - Ignition fault,
automatic log wood func-
tion
There was no need for automatic ignition using an igni-
tion blower. The ignition fan is on the outside of the left
or right boiler cladding. The hot ignition air is trans-
ferred to the fuel through an ignition pipe. The ignition
pipe opens into the filling chamber just above the stain-
less steel combustion grate.)
Defective fuel filling
–
refer to description of operating mode
Filling chamber or combustion chamber door not
closed properly.
–
Check.
Sediment in the mouth of the ignition pipe (in the
filling chamber)
–
Visual inspection, cleaning
Insufficient boiler cleaning
