10.4 DAMAGED SMOKE EXTRACTION FAN ALARM
It goes off when the smoke extraction fan breaks down. If this
happens, the thermo-stove stops and the display will show the
following alarm (see drawing D68). Right after, the turn-off stage will
be immediately activated.
To deactivate the alarm press button 4 and the thermo-stove will
return to the normal state after carrying out the final cleaning.
10.5 IGNITION FAILURE ALARM
In case of ignition failure (after 20 minutes at least) the display will
show up an alarm as follows (see drawing D69).
To deactivate the alarm press button 4 and the thermo-stove will
come to the normal state after doing the final cleaning.
10.6 SWITCHING-OFF FAILURE DURING WORKING PHASE
If the flame extinguishes during the working stage and the smoke
temperature goes lower than the minimum working threshold,
the alarm does go off and the turn-off stage will be immediately
activated (see drawing 70).
To deactivate the alarm press button 4 and the thermo-stove will
come to the normal state after doing the final cleaning.
10.7 THERMAL ALARM
If in working phase the thermal security alarm shows up (see
drawing D71), the turn-off stage will be immediately activated. This
alarm means an overheating of the internal part of the tank; this
device locks the operation of the machine. The restart needs to be
done manually by an authorised technician.
The replacement of the 90ºC safety device is not included in the
warranty unless the technical assistance centre demonstrates a
faulty component.
10.8 COMBUSTION CHAMBER PRESSURE ALARM
This alarm is triggered when there is a pressure change in the
combustion chamber (door open, dirty ash reservoirs, down
draughts, blocked flue, etc). The electronic pressure switch locks
the operation of the thermo-stove and shows the alarm. After that the
turn-off stage will be immediately activated (see drawing D72).
10.9 LACK OF PRIMARY AIR INTAKE FLOW ALARM
Your thermo-stove has a flow sensor placed inside the primary air
suction pipe. It detects the proper circulation of combustion air and
the smoke exhaust. In case of insufficient air intake (due to incorrect
smoke outlet or improper air intake), the sensor sends a "lock"
signal. After that the turn-off stage will be immediately activated (see
drawing D73).
10.10 AUGER MOTOR/ GEAR FAILURE ALARM
The control of the fuel load delivered to the thermo-stove is
automatically monitored through the electronic programming. This
alarm goes off in the event that the auger breaks down and feeds
continuously. If this happens, the thermo-stove stops and the display
will show the following alarm. Immediately afterwards, the turn-off
stage will be activated (see drawing D74).
In case this alarm appears you must be in touch with the technical
support service.
10.11 FLOW SENSOR FAULT
In case of a failure of the flow sensor, placed on the primary air
intake tube, a lock out signal is sent to the thermo-stove and right
after the turn-off stage will be immediately activated. See drawing
D75.
In case this alarm appears you must be in touch with the technical
support service.
