9 Possible Malfunctions
All possible malfuntions in the operation of this device can be di-
vided into two major groups.
Gruppe I:
Error
during the initial start of the boiler or the first start
after a short deactivation period.
Gruppe II:
The boiler switches off during run mode. After re-
aching set temperatures and a forced pause, the boiler will not
start again without manual reset.
9.1 Group I
Adhere to the installation guidelines in the ‚Montage‘ part – es-
pecially the flue system (diameter, number of bends, sealing, ...),
as well as the chimney (diameter, height, sealing of revision ope-
nings, pullution etc.).
The most common error message of this group is „E12“. In case
of insufficient flame formation after ignition and if the flue gas
temperature failes to rise, the igniter will be displayed as active,
but the boielr will switch to extingushing phase. If this happens,
check the following:
-
Bad pellet quality or wet pellets.
Solution:
only use, dry, high quality pellets.
Combustion air temperature is too low
(below 0°C).
Solution:
set a longer ignition time t02 to 30 – 40
seconds.
-
Power supply voltage is low (much below 230 V);
the igniter output is insufficient.
Solution:
set a longer ignition time t02 to 30 – 40
seconds. If this measure is unsuccessful, install an AC
adapter that provides 230 V.
-
Pellet starting load insufficient, no flame formation.
Solution:
Have qualified personnel check for mechanical
problems on the auger or the motor.
-
Flame formation is successful, but the boiler remains
in stabilisation phase and does not enter run mode.
Solution:
The boiler needs more fuel in the combustion
chamber. Set a longer timespan in parameter t03 – increase
it step by step for a few seconds each. Please also mind the
following reference.
-
There is flame formation after the timespan set in t03,
but the boiler does not switch to stabilisation phase
t04. The flame is getting weaker and the flue gas tem-
perature is sinking. The boiler switches to extingu-
ishing phase.
Solution:
Decrease the timespan set in parameter t04
(stabilisation phase) it step by step for a few seconds each.
Please also mind the previous reference.
The boiler controller may display the following messages resulting from a malfuntion.
Er01
Error – High voltage (even when boiler is not in operation)
Er02
Error – High voltage (only when fan is in operation)
Er03
Error – Low flue gas temperature; boiler ceases operation
Er04
Error – High boiler temperature; boiler ceases operation
Er05
Error – High flue gas temperature; boiler ceases operation
Er07
Error – Signal error between encoder and controller
Er08
Error – Encoder encouters problems with counter
Er09
Error – Low water pressure
Er10
Error – High water pressure
Er11
Error – Wrong time-setting
Er12
Error – Ignition failed
Er15
Error – Low power supply voltage
Er17
Error – Error in vacuum actuator
Er18
Error – Low pellet level (not used)
Er39
Error – Vacuum actuator defective
Er41
Error – Minumum negative pressure could not be reached
Er42
Error – Negative pressure to high
