14 DIAGNOSTIC ERRORS
During operation, if a fault is detected the stove
turns off, following the cooling cycle, and an error
message is shown on the display, which can
only be eliminated manually. Even if in automatic
operating mode, the stove waits for the alarm
reset command indicating that the fault has been
acknowledged. Following is a list of the possible
errors:
14.1 ERROR 1 NOT ACTIVE
14.2 ERROR 2 PRESSURE SWITCH ALARM
If the pressure gauge is activated due to insufficient
vacuum of the flue gas extraction, the cycle stops
heating with error 2. This may be caused by the
obstruction of flue gas extraction or expulsion.
14.3 ERROR 3 NO PELLETS
If during operation the combustion chamber
temperature drops below the set limit. The cycle
ends with a system error. This may be due to a
lack of fuel or the blocked distribution of the fuel.
14.4 ERROR 4 NOT ACTIVE
14.5 ERROR 5 HIGH EXHAUST
TEMPERATURE ALARM
14.6 ERROR 6 SAFETY THERMOSTAT
If the safety thermostat is triggered during
operation, the pellets will stop loading automatically
and the stove will stop heating with error 6.
Once the temperature has dropped below the
minimum limit, consent for operation is once more
activated, but as a precautionary measure, prior to
each ignition following an error, always check the
causes and then restore them.
14.7 ERROR 7 SMOKE EXTRACTION
MOTOR ALARM
During the heating phase, the smoke extraction
motor is monitored; if its speed drops below a
minimum speed equal to 50% of the set RPM
value, an error is generated due to malfunction
of the smoke extraction motor and the stove will
switch to cooling mode at maximum speed. This
problem may also be due to ash deposited in
the flue gas pass and due to insufficient routine
maintenance.
14.8 ERROR 8 NOT ACTIVE
14.9 ERROR 9 NOT ACTIVE
14.10 ERROR 10 NOT ACTIVE
14.11 ERROR 11 NOT ACTIVE
14.12 ERROR 12 POWER FAILURE
If during any stage of stove operation there is a
mains power failure, when the power returns, a no
mains power alarm is notified and the stove shuts
down. Even a power failure lasting a few seconds
generates the alarm.
14.13 ERROR 13 NOT ACTIVE
14.14 ERROR 14 NOT ACTIVE
14.15 ERROR 15 IGNITION FAILURE
If after an ignition cycle, the stove does not reach
the minimum operating temperature, the cycle
ends with an error and the system proceeds with
scheduled cooling. This may be due to a lack of
fuel, dirty burn pot or dirty or defective igniter.
14.16 ERROR 16 INTAKE SENSOR
FAULT (only if intake sensor enabled)
If, during operation, the board detects a malfunction
of the intake sensor, the stove will switch to cooling
mode.
14.17 ERROR 17 NOT ACTIVE
14.18 ERROR 18 FUME EXTRACTION
CIRCUIT FAULT
If during operation the system detects insufficient
air extraction, the cycle ends with a system
error and proceeds with scheduled cooling. The
minimum level is set in par. 107. Alarm active if
intake sensor management enabled, by setting
par.101 to a value other than 0.
14.19 ERROR 19 OVERTEMPERATURE
ALARM
This function is enabled through the system
parameter 63. The board temperature is
monitored and, if it exceeds 70° for more than 3
minutes, the stove switches to cooling mode for
overtemperature.
