1 - Error in internal memory
An error has occurred in the memory of the boiler con-
trol. Check whether the customer/system-specific set-
tings are present in the boiler control.
2 - Feeder sensor short circuit
The temperature sensor of the pellet auger has short-
circuited and must be replaced.
3 - Ignition not possible! Check the container fill
level sensor
Open the inspection cover on the pellet storage tank.
Check whether there are any pellets in front of the sen-
sor. If there are no pellets present, then the green LED
should not light up. If it does, wipe the sensor. If there
is no change, replace the sensor.
4 - Extraction room may be empty
Alarm is triggered when the runtime of the conveyor
auger in the storage area is exceeded and when the
level sensor in the pellet storage tank reports empty.
Check the pellet level in the storage area.
5 - Flue gas temperature too low
The time limit for reaching the calculated flue gas requi-
red temperature has been exceeded. Clean the com-
bustion grate, combustion chamber and flue pipe.
6 - Flue gas sensor disruption
The flue gas temperature sensor has a defect and
must be replaced.
7 - Flue gas sensor shows wrong measured value
The flue gas temperature sensor has a defect and
must be replaced.
8 - Feeder sensor disruption
The temperature sensor of the pellet auger has been
disrupted and must be replaced.
9 - Flue gas sensor short circuit
The flue gas temperature sensor has a defect and
must be replaced.
10 - Factory settings have been loaded
The customer-specific settings in the boiler control
have been lost.
11 - Induced draught fan error
Message is triggered when the burner heats, but no
speed is measured at the induced draught fan (IDF).
Acknowledge the message, the IDF will be tested for
one minute. After the test, an OK or Not OK message
will be output.
12 - Induced draught fan running
Message during active IDF test run.
13 - The functionality of the induced draught fan
is no longer intact
Cleaning of the exhaust pipe may be necessary.
14 - Maximum suction time reached
Message is triggered when a specified time is excee-
ded during the suction filling of the pellet storage tank.
Cause / action
–
The pellet storage area runs empty / > check pellet
level in storage area
–
- Suction turbine, extraction motor or level sensor
are defective / > acknowledge message and check
(look/listen) whether the suction turbine or extrac-
tion motor starts up.
–
The pellet hose is blocked / > visually check the
pellet hose for blockage.
–
Inspection cover on the pellet supply container lea-
king / > contact qualified personnel.
15 - Feed sensor shows wrong measured value
The temperature sensor of the pellet auger is defective
and must be replaced.
16 - Lambda sensor defective
Message is triggered when the residual oxygen con-
tent in the induced draught fan is measured at over
15.5 % for a period of 1.5 hours.
17 - Boiler sensor defective
Message is triggered when a boiler temperature sensor
short-circuits (display -30.0°C) or a disruption occurs
(display 150.0°C). The burner stops, all pumps are
switched off (to prevent a rise in the boiler tem-
perature).
18 - Boiler temperature is too high
