CAUSE
A.
Dirty boiler, carry out seasonal maintenance.
B.
Excessive pellet range and/or high calorific power of the same. Check and possibly reduce
the on times of the cochlea especially to the highest powers.
C.
The fumes probe does not read correctly, check its location and check the operation status
of the fumes. Check the display for the temperature of the fumes, which must be
appropriate for the likely actual temperature of the fumes. If the indicated temperature is
very high (900 degrees Celsius), the probe that detects the temperature of the fumes must
be replaced because it is damaged or interrupted. If replacing the probe the temperature
indication remains wrong, you have to replace the electronic control unit that does not
correctly interpret the temperature detected by the probe itself.

long time. From the System Menu – Outputs Test, start the Fumi Fan Speed test, in case the
extractor turns to check the correct encoder connections. If the extractor does not turn replace
the extractor or the electronic control unit.
