16 Maintenance and cleaning
7 - Flue gas sensor wrong measured value
The flue gas temperature sensor has a fault and must
be replaced.
9 - Flue gas sensor short circuit
The flue gas temperature sensor has a fault and must
be replaced.
11 Error rotational speed feedback
Message is triggered when the burner is active but no
speed is measured at the induced draught fan (ID
fan).
► Acknowledge the message, the ID fan will be
tested for one minute. After the test, an OK or
Not OK message will be output.
12 - Rotational speed feedback test
Message during active ID fan test run.
13 - Rotational speed feedback Not OK
Cleaning of the flue gas pipe may be necessary.
14 - Maximum suction time reached
This message is only possible in conjunction with a
pellet suction system. Message is triggered when a
specified duration is exceeded during the suction
filling of the intermediate pellet store.
The pellet storage area is empty
► Check pellet level
Suction turbine, extraction motor or filling level
sensor is defective
► Acknowledge the message and check (see/l-
isten) whether the suction turbine or extraction
motor commence operation
Blockage in pellet hose
► Check, if possible rectify blockage
► This may be caused by an excessive dust con-
tent (poor pellet quality)
16 - Error lambda sensor measurement
Message is triggered when the residual oxygen con-
tent in the ID fan lag is measured at over 15.5% for a
period of 1.5 hours.

17- Error boiler temperature sensor
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
temperature).
18 - Boiler temperature is too high
19 - Extraction auger is blocked
The thermal contact on the motor of the storage area
auger has triggered. The boiler is still ready for oper-
ation.
The suction process took too long and the motor
overheated
The motor was blocked by a blockage and over-
heated
Electrical contact fault in the motor supply line
► Switch the boiler off and allow the motor to cool
down!
► Visually inspect the pellet hose for blockage, rec-
> 42
tify as necessary.
20 - First ignition attempt was unsuccessful
The boiler remains in operation and starts a second
ignition attempt. - If the second ignition attempt is also
unsuccessful, message No. 40 is shown.(fehlender
oder ungültiger Codeausschnitt)
23 - Communication with electronic module is
interrupted
The CAN bus or RS-485 communication between the
operating element (display) and the electronic mod-
ule has been interrupted.
Interruption in the bus cabling
► Check cable connection
Error in the electronic module's power supply
► Check, replace if necessary
Incorrect device address for the electronic mod-
ule
► Check whether the correct address is entered in
the module for the intended use of the module.
For further information, see the module's install-
ation manual.
Fuse F1 or F3 on electronic module is defective
► Check, replace if necessary
