Problem Cause Solution
E4
THRESHOLD TEMPERATURE
Evacuation system obstructed Clean the smoke evacuation system
Faulty electronic board. Replace the electronic board (use only original parts).
Threshold temperature probe is faulty Replace the control probe (use only original parts).
Incorrect position of the smoke probe.
Check the proper position of the probe in its seat (see wiring
diagram).
Incorrect parameter settings. Check proper settings of the parameters.
E8
SMOKE TEMPERATURE PROBE
No connection of the 2-pole connector of
the smoke probe to the electronic board.
Check the proper connection/position of the connector (see
wiring diagram).
Faulty electronic board. Replace the electronic board (use only original parts).
Incorrect position of the smoke probe. Check probe connection in its seat.
Faulty smoke probe. Replace the smoke probe (use only original parts).
The stove runs for 10 minutes
then shuts down.
The temperature probe is stuck.
Repeat the start procedure. Contact an authorised technician
if the problem persists.
The exhaust smoke has not reached optimal
start temperature.
Repeat the start procedure. Contact an authorised technician
if the problem persists.
The temperature probe may be poorly
connected.
Check the wiring and the connection.
Chimney clogged. Clean the smoke ue.
No lit See “E7”.
Faulty electronic board. Replace the electronic board (use only original parts).
Auger channel clogged. See the section “LOADING AUGER”.
E6
AUGER SAFETY
Auger fault. Replace the auger (use only original parts).
Faulty electronic board. Replace the electronic board (use only original parts).
Incorrect parameter settings. Check proper settings of the parameters.
E3
THERMAL SAFETY
Evacuation system obstructed Check and clean the smoke evacuation system
High temperature of the pellet hopper.
Check proper installation of the stove (parameters, length,
high smoke exhaust, ...)
Automatic rearm thermostat is faulty. Replace the thermostat (use only original parts).
The automatic rearm thermostat may not be
connected properly.
Check proper thermostat connection.
Faulty electronic board. Replace the electronic board (use only original parts).
00 E10 P4
ROOM TEMPERATURE PROBE
Probe disconnected.
Check the proper connection of the room probe (see the
section “ELECTRICAL CONNECTIONS AND CONTROL
DEVICES”).
Faulty probe. Replace the room probe (use only original parts).
Faulty electronic board. Replace the electronic board (use only original parts).
E12
ENCODER
Encoder disconnected. Check the connections.
Faulty encoder.
Check the encoder work state and replace the smoke motor
if necessary (use only original spare parts).
Check the encoder work state and replace the electronic
board if necessary (use only original spare parts).
