3.8 Remote anomaly code
If the boiler is connected to remote (option
-
al), a code that indicates a boiler anomaly is
displayed in the centre of the display.
The anomaly in progress is indicated by a
numeric code followed by the letter
E
.
The table summarises the possible codes
displayed on the remote.

3.9 Flue probe
The flue probe 21 and safety thermal fuse
26 indicated in Fig. 3.7 are a safety device.
The flue probe 21 intervenes when the flue
temperature exceeds 110°C placing the
boiler in safety block switching it off.
To reset normal boiler functioning, just press
the 14 (Fig. 3.5) key.
If flue probe 21 does not intervene and,
therefore does not send the boiler into se
-
curity lockout, thermofusible 26 enters into
function as a further safety measure.
This component sends the boiler into se
-
curity lockout when the flue temperature
reaches 167°C.
To restore the normal operation of the boil
-
er, contact the Authorized Service Centre.
