After completing the operations:
ƒ refit the previously removed components
ƒ power the boiler and turn on the gas tap.
Adjust the boiler as explained in paragraph "3.16
Adjustments" and paragraph "3.17 Gas valve calibration".

3.19 Signalling and faults

In there is a fault, the
sec OFF). The backlight will flash for 1 min (1 sec ON, 1 sec
OFF) and then switch off, but the bell will carry on flash-
ing. The 4-digit area of the display will show a sliding
message with the error code.
The following icons may appear when a fault arises:
− lights up for a flame alarm (E010)
− RESET lights up for an alarm that needs to be manually
reset by the user (e.g. a flame lockout)
− lights up along with the
lockout and water failure faults)
In addition, when parameter P3.02 is set with a value of
1, meaning that a water pressure transducer is fitted, the
pressure value is shown when it is higher than 5.0 bar
(excessively high pressure); the boiler carries on working
as these are merely info messages.
With pressure lower than 0.8 bar (excessively low pressure)
the boiler stops functioning.
In these cases, the pressure value, with the relative
measurement unit, is also shown at the end of the
following error messages:
• E041
• E040
Reset function
To reset boiler operation in the event of a fault, press
the RESET button. At this point, if the correct operating
conditions have been restored, the boiler will restart au-
tomatically. Up to 5 consecutive reset attempts can be
made on the interface, after which the display will show
code E099. In this case, the boiler must be disconnected
from the electricity supply and then reconnected again,
to reactivate operation.

If the reset attempts fail to activate boiler opera-
tion, contact the Aftersales Service.
Fault E020: in the event of frequent intervention of the
limit thermostat (especially in the CONDEXA HPR 55 and 70
boilers), check whether parameter P4.11 is programmed at
1 and take it to 0 to reset the timings envisaged for the
heating phases.
Fault E041: if the pressure value falls below the safety value
of 0.8 bar, the boiler shows fault code E041 for 10 min.
When the transitional time has finished, if the fault per-
sists the fault code E040 is displayed.
When fault E040 has occurred, the boiler must be man-
ually filled via a filling system (to be installed on the
system, preferably connected to the return line) until the
pressure is between 1.5 and 2.0 bar.
Then press RESET.
Close the filling system, making sure you hear the me-
chanical click.
After filling, run the automatic venting cycle as explained
in paragraph "2.14 Filling the heating system and elim-
inating air".

If pressure drops happen very frequently, contact
the Aftersales Service.
Fault E060: on heating-only models with a storage tank
with probe connected, fault E060 prevents operation in
DHW mode.
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 has been completed, reset to
zero the total hour meter with special kit supplied as an
accessory following procedure indicated below:
ƒ access the technical parameters as explained in para-
graph "1.17 Accessing the parameters"
ƒ select menu P3 and then item P3.12, using the
buttons
ƒ set the parameter value at 1, confirming with
NOTA: 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 menu as explained in paragraph
"3.20 INFO menu" and visualise item I015 to see the
value of the flue gas probe meter.
