To scroll through the values, press the 12 key
(previous INFO) and 14 key (next INFO).
To exit INFO mode, simply:
• wait 15 minutes without pressing any key;
• switch off the electric power supply;
• press and hold the 12 and 14 keys simulta-
neously for 5 seconds (Figure 3.9) (one level
up).
The table summarises the possible values visi-
ble in INFO mode.

3.8 Remote fault code
If the optional remote is connected to the boil-
er, a code can be shown on the central part of
the display that indicates a boiler anomaly.
The current anomaly is indicated by a numeric
code followed by the letter
E
.
The anomaly codes sent to the remote are the
same as those shown on the display (see "LCD
SIGNALS" on page 8).
3.9 Flue gas probe and thermal fuse
Thermofuse tripping involves a
safety lockout, and requires reset-
ting by an Authorised Service Cen-
tre.
The flue gas probe and thermal fuse 17 indicat-
ed in Figure 3.11 are safety devices.
The flue gas probe and 17 are triggered when
the flue gas temperature exceeds 110°C, acti-
vating the boiler safety lockout, shutting it off.
To reset normal boiler operation simply press
the button 13 (Figure 3.9).
