of the connecting wires must be 0 Ohm). If the thermostat is working properly but the alarm
remains, you will need to check the electrical connection between the thermostat and the
electronic control unit (the wire resistance must be 0 Ohm) and if necessary you will need to
replace the connection fastons. If the electrical connection is also working, replace the
electronic control unit.
Warning Er 02
PROBLEM
The depression inside the machine body is less than <20 Pa and the state intervened.
ACTION
Unlock the boiler by long-pressing the control panel - turn control panel on and off
button.
CAUSE
A.
The boiler door was not closed perfectly. Close the door correctly of the combustion
chamber. Non-compliant and/or dirty fumes discharge system. Check the implementation
of the chimney in accordance with the UNI 10683:2012 standard. Check the cleaning status
of the chimney, if necessary clean the same carefully by eliminating all combustion residues
inside, especially on changes of direction and horizontal sections.
B.
Non-compliant and/or dirty fumes discharge system. Check the implementation of the
chimney in accordance with the UNI 10683:2012 standard. Check the cleaning status of the
chimney, if necessary clean the same carefully by eliminating all combustion residues inside,
especially on changes of direction and horizontal sections..
C.
Non-airtight upper and lower fumes lap caps. Check and possibly replace the seals. If
deformed replace the seals.
D.
Smoke extractor and/or capacitor not working. Verify that the extractor is working correctly.
E.
Check that the property is working properly or that it does not obstruct the transparent
silicone tube in its entire length.
Warning Er03
PROBLEM
The boiler was accidentally switched off (the temperature of the fumes dropped below 45 degrees
Celsius).
ACTION
Unlock the boiler by long-pressing the control panel turn the control panel on and off
CAUSE
A.
Pellet range not sufficient to maintain combustion (average longer pellets and/or poor
calorific power). Check and possibly increase the technical parameters inherent in the On
times of the cochlea (AUGER), especially in the lower powers.
B.
Excessive temperature drops. Make sure there are no external vents near the fumes output,
which cool the probe. The fumes probe does not read correctly.
C.
Non-compliant or dirty smoke exhaust system and check the chimney in accordance with UNI
10683:2012 standard.
