POSSIBLE TROUBLESHOOTING
In the event of problems the thermo-stoves stops automatically and runs the shutdown process and the display shows text
regarding the motivation of the shutdown (see the various alarms below).
Never pull the plug during shutdown on account of malfunction.
If the event of malfunction, to restart the thermo-stoves it is necessary to let the shutdown procedure proceed (10 minutes
with acoustic signalling) and then press the 0/1 key on the synoptic panel.
Do not turn the stove on again before checking the cause of the malfunction and CLEANING/ EMPTYING the crucible.
INDICATION OF POSSIBLE CAUSES OF MALFUNCTION AND INDICATIONS AND REMEDIES:
1) H2O PTC_FAULT: Shuts down due to the water temperature sensor being broken or disconnected.
Check connection of the sensor to the control board. Verify functionality by means of a cold test
2) Verific./extract.: Shuts down due to the revolution sensor of the smoke extractor motor detecting an anomaly.
- Check smoke extractor functionality (connection of the revolution sensor)
- Check smoke channel for dirt
3) Stop/Flame: Shuts down due to a drop in smoke temperature (intervenes if the thermocouple detects a smoke temperature that is
lower than that which is set, thereby interpreting it as a flame failure).
The flame may not go on for the following reasons:
- lack of pellets
- too many pellets in the combustion chamber have suffocated the flame
- the maximum thermostat / pressure switch / water safety thermostat has intervened to 'stop' the gear motor
4) Block_FI/NO Start: Shuts down due to incorrect smoke temperature during ignition (intervenes if the flame fails to appear within
a maximum of 15 minutes, or if the ignition temperature is not reached).
Distinguish either of the following cases:
The flame has NOT appeared
Verify:
- positioning and cleanliness of combustion chamber
- resistance functionality
- room temperature; if lower than 3 °C a fire lighter is needed
5) Failure/Power: Shuts down due to an electricity failure (not a defect of the thermo-stoves).
Check electricity connection and drops in voltage.
6) Fault/RC: Shuts down due to a failure occurring in the thermocouple or it being disconnected
Verify connection of thermocouple to the control board. Verify functionality in a cold test.
7) smoke °C/high: Shuts down due to excessive smoke temperature
An excessive smoke temperature may occur because of the following: unsuitable pellet type, anomaly in smoke extraction, blocked
smoke channel, incorrect installation, gear motor 'drift'.
8) H2O TEMP ALARM: Shuts down due to water temperature being higher than 90 °C.
An excessive temperature may occur because of the following:
- system too small: ask the DEALER to activate the ECO function
- blockage: clean the exchanger pipes, the combustion chamber and the smoke outlet.
9) Verific./Air Flow: (activates if the pressure sensor (vacuum gauge) detects insufficient values)
The vacuum may be insufficient in the event of an open door:
- imperfect door sealing (i.e. gaskets) / - problems with air suction or smoke expulsion/ - clogged chimney flue
- vacuum gauge reading point dirty with soot (clean with dry air).
Check calibration. Request DEALER assistance with parameters.The alarm may also be set off during the start-up phase.
10) check_a/entrace:
Pascal value higher than the "AC max PA" threshold, displayed only for 2" without the blockage phase being activated.
11) STOP T/ SCREW 1:
Auger 1 turns when it should be still, probable motor control triac malfunction/wiring connection error.
12) STOP G/SCREW 1: (intervenes when the gear motor 1 is blocked or malfunctioning)
Check the wiring of the gear motor 1 or else replace it.
The flame has appeared but after Ignition appears on the display,
"Block_FI/NO Start" appears
Ask the DEALER to check:
- thermocouple functionality
- set parameters for ignition temperature
