4.20 Lights and faults
When there is a fault the icon
0.5sec OFF, the backlight blinks for 1min with a frequency of 1sec ON and
1sec OFF after which it switches off; while the bell continues to flash. On
the 4 digits of the display a scrolling message that describes the error code
is shown.
When a fault occurs the following icons can appear:
it comes on when there is a flame alarm (E010)
-
- RESET comes on when there is an alarm that requires the manual reset
by the user (flame lockout for example)
comes on together with the icon
-
alarms.
Moreover, when the WATER TRANSDUCER parameter is set to 1 and
therefore there is a water pressure transducer present, the pressure value,
with the relative unit of measurement should be displayed at the end of the
following error messages:
• E041 WATER TRANSDUCER LOAD THE SYSTEM
• E042 WATER TRANSDUCER
• WATER PRESSURE HIGH CHECK THE SYSTEM
• WATER PRESSURE LOW CHECK THE SYSTEM.
Reset function
In order to reset the boiler's operation in the event of a fault, it is necessary
to press the RESET button.
At this point, if the correct operating conditions have been restored, the
boiler will restart automatically.
There are a maximum of 3 consecutive attempts at a release by the REC10.
In case of all the attempts are exhausted the definitive fault E099 occurs on
the display. The boiler will need to be unlock by cutting off and reconnecting
the electrical supply.
b
If the reset attempts do not activate the boiler, contact the Technical
Assistance Centre.

For fault E041
If the pressure drops below the safety threshold of 0.3 bar the boiler displays
the fault code <<E041 water transducer load the system>> for a transitional
time of 30sec.
When the transitional time has finished, if the fault persists the fault code E040
30 32 34
is displayed.
When the boiler has fault E040 manual loading should be carried out using the
filler tap ( A ) until the pressure is between 1 and 1.5 bar.
Then press RESET.
Close the filling tap, making sure to hear the mechanical snap.
At the end of the procedure, proceed with the automatic vent cycle as described
in the section "3.16 Filling the heating system and eliminating air".
b
If the drop in pressure is very frequent, contact the Technical Assistance
Centre.
For fault E060
The boiler is working normally, but does not provide any stability of the
domestic hot water temperature that, in any event, is supplied at a
temperature of around 50°C. The intervention of the Technical Assistance
Service is required.
For fault E091
The boiler has an auto-diagnostic system which, based on the total number
of hours in certain operating conditions, can signal the need to clean the
primary exchanger (alarm code E091).
Once the cleaning operation (made with special kit supplied as an
accessory) it is necessary to reset to zero the total hour meter following
procedure indicated
ƒ access the technical parameters as explained in the section "3.21
Access to the parameters"
ƒ select the CONF menu and then EXHAUST PROBE RESET with the
keys and
ƒ set the parameter to 1 confirming the selection with
NOTE: The meter resetting procedure should be carried out after each in-
depth cleaning of the primary exchanger or if this latter is replaced.
The total hours can be verified in the following way:
ƒ access the INFO menus as indicated in the paragraph "4.21 INFO
menu" at EXHAUST PROBE RESET to display the value of the flue
gases probe meter.
