...the flue pipe is dirty, blocked or not correctly installed
If the flue is dirty, blocked or not correctly installed, pellet loading will not start, thus the appliance will not switch on. If the flue is obstructed during
normal operation, the appliance activates the “
DEPRESS.-FAILURE
”
alarm.
...the appliance is overheated
If the water in the boiler body is overheated (>94°C), the pellet will not be loaded because the manual reset thermostat cuts in. If this happens during
normal operation, the appliance switches to
“THERMAL SAFETY” alarm
. It is therefore necessary to reset the
“manual reset thermostat”
(see
“
Components of the appliance
”)
before switching the appliance on again. To reset, it is necessary to remove the black cap and press the button below.
...there is a power outage (blackout)
If a power blackout occurs for a shorter time than Pr48, when power is restored, the appliance will immediately re-start in the working mode (recovering
the set working power).
If the outage lasts longer than Pr48, when power is restored, the appliance will enter the
“STOP FIRE” (stand
-by)
mode running the entire switch-off
cycle until cooling. When this phase is over, the appliance can be restarted resuming work at the set power.

Alarm signals
The following table describes the different alarms which may appear.
DISPLAY VISUALISATION
ORIGIN OF ALARM
AL 1 -
BLACKOUT ACTIVE ALARM
Blackout alarm. When power is cut off under determined conditions
(see
“What
happens if…”
)
AL 2 -
FLUE GAS PROBE ACTIVE ALARM
Faulty or disconnected flue gas temperature probe.
AL 3 -
HOT TEMP ACTIVE ALARM
Flue gas over-temperature. Before displaying the alarm, or when flue gas maximum
temperature is reached (Pr14). the display shows
“HOT FLUE GAS”.
AL 4 -
EXTRACTOR-FAILURE ACTIVE ALARM
Faulty flue gas extractor. When the encoder (tachometer) in the extractor detects an
extractor speed equal to 0.
AL 5 -
NO IGNITION ACTIVE ALARM
No ignition. When the flue gas minimum temperature (Pr13) is not reached within the
maximum ignition cycle time (Pr01).
AL 6 -
NO PELLET ACTIVE ALARM
Sudden shut-down during the work phase. When, during the work phase, the flue gas
temperature drops below the minimum threshold (Pr28).
AL 7 -
THERMAL-SAFETY ACTIVE ALARM
Temperature safety device. When the safety thermostat (water over temperature) or
one of the micro switches (contact interrupted) fitted in the fire door or pellet container
door cuts in. If the safety thermostat cuts in the boiler stove must be manually
rearmed.
AL 8 -
DEPRESS.-FAILURE ACTIVE ALARM
Poor depression. When the flue gas pressure switch cuts in (contact interrupted) due
to poor draught in the flue pipe.
AL 9 -
WATER PROBE ACTIVE ALARM
Faulty or disconnected water temperature probe.
AL c -
SF TRIAC ERROR ACTIVE ALARM
Screw feed TRIAC error. When the screw feed gear motor does not stop for at least
0.2 seconds during the maximum work interval of 8.0 seconds. Before the alarm is
activated a safety relay cuts in and forcibly cuts off the power supply to the gear motor.
Every alarm causes the appliance to switch-off immediately. The alarm status is reached after the time set on Pr11
(set by default to 60 sec)
and can
be reset by pressing and holding the ON/OFF button (4).
