POSSIBLE TROUBLESHOOTING
BLOCKED – HIGH WATER TEMPERATURE (this occurs if the water temperature sensor reads a
8) Signalling:
temperature above 90°C)
Problem:
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.
BLOCKED – INSUFFICIENT DRAFT (activates if the pressure sensor (vacuum gauge) detects
9) Signalling:
insuffi cient values)
Problem:
The vacuum may be insuffi cient in the event of an open door:
- imperfect door sealing (i.e. gaskets) / - problems with air suction or smoke expulsion
- clogged chimney fl ue
- vacuum gauge reading point dirty with soot (clean with dry air).
Actions:
Check calibration. Request DEALER assistance with parameters.The alarm may also be set off during the
start-up phase.
EXCESSIVE DRAFT
10) Signalling:
Problem:
Pascal value higher than the "AC max PA" threshold, displayed only for 2" without the blockage phase
being activated.
BLOCKED – SCREW 1: (intervenes when the gear motor 1 is blocked or malfunctioning)
11) Signalling:
Actions:
Check the wiring of the gear motor 1 or else replace it.
ROTATION FAULT SCREW 1
12) Signalling:
Azioni:
Auger 1 turns when it should be still, probable motor control triac malfunction/wiring connection error.
BLOCKED – SCREW 2: (intervenes when the gear motor 2 is blocked or malfunctioning)
13) Signalling:
Actions:
Check the wiring of the gear motor 2 or else replace it
BLOCKED – HIGH TEMPERATURE SCREW 2
14) Signalling:
Problem:
The probe connected to screw 2 is reading a higher temperature, the boiler shuts down
NTC SENSOR FAULT SCREW 2
15) Signalling:
Problem:
Auger temperature sensor 2 malfunctioning or disconnected.
BURNER BLOCKED
16) Signalling:
Problem:
The burner did not return to its seat after automatic cleaning.
N.B.:
The combustion chambers and smoke ducts connected to the solid-fuel appliances must be cleaned once a year (check if your
country has specifi c legislation covering this).
Failure to regularly check and clean increases the likelihood of a fi re in the chimney pot.
In the case of a fi re in the boiler, in the fl ue or in the chimney, proceed as follows:
- Disconnect the power supply
- Use a carbon dioxide (CO
2
- Call the fi re brigade
DO NOT ATTEMPT TO PUT THE FIRE OUT WITH WATER!
After the event, have the appliance checked by an authorised Service Centre and have an authorised technician check the fl ue.
