Caution:
only use the parameter relating to the boiler installed.

3.11 FLUE TEST.
To define the value to set in the ”flue length”
“F0” parameter, detect the parameters during
the “flue test”.
Attention:
Ensure that the condensate drain
trap has been filled correctly before carrying
out the test.
To activate this mode, the boiler must be in
“stand-by” mode, which is visible when the
(
) symbol appears.
N.B.:
if the boiler is connected to the CAR
V2
the
“stand-by” function can only be activated via the
remote control panel.
To activate the function, press the “Reset” (2) and
“on/off” (6) buttons simultaneously until func-
tion activation, which is displayed by indicating
the fan operation speed (in hundreds of revs) and
ignition of the flashing “D.H.W.” (8) and central
heating symbols.
The appliance remains in this mode for a max-
imum period of 15 minutes, keeping the fan
speed constant.
3-12
This function ends once 15 minutes have elapsed,
or by disconnecting supply voltage to the boiler,
or by pressing the “on/off” (6) button for approx-
imately 8 seconds.
Check the ΔP between the test pressures (fig. 1-29
Ref. 13), in compliance with the values indicated
in the following table:
Parameter F0 Pressure
0 < 145 Pa
1 146 ÷ 178 Pa
2 179 ÷ 205 Pa
Detected Value
(Upon first check)
N.B.: examinations are carried out by sealing the
holes provided to analyse the flues, making them
pneumatically sealed.
Attention:
should there be a boiler malfunction,
you can carry out a flue test to check that there
are no obstructions in the flue system. Different
values to those indicated in the previous tables
indicate a flue system malfunction, especially
a flue system with excessive load losses or ob-
structed system.
3.12 PROGRAMMING THE P.C.B.
The boiler is prepared for possible programming
of several operation parameters. By modifying
these parameters as described below, the boiler
can be adapted according to specific needs.
To access the programming stage, set the DHW
selector in the “6 o' clock” position and the
heating selector in the “9 o' clock” position and
press the “Reset” and “Summer/Winter” buttons
for about 8 seconds (Fig. 3-13).
3-13
Once the programming mode has been accessed,
scroll through the five menus (G, P, t, A, F) by
pressing the “Summer / Winter” button for 1
second.
Use the ''D.H.W. regulator'' selector to select
the parameter (within the same sub-menu)
and rotate the ''C.H. regulator'' selector to alter
the value.
Press the "Reset" button for 1 second to store the
altered parameters.
If the parameters are stored successfully, "88"
appears on the indicator (Ref. 14 fig. 2-1) for
2 seconds.
Exit the programming mode by waiting for 15
minutes or by pressing the “Reset” and "Summer/
Winter" buttons at the same time.
Attention: if necessary the default values relating
to parameters “S” and “P0 ÷ P2” can be altered by
temporarily modifying the type of gas (parameter
“G”) and by restoring it according to the actual
operating conditions (wait for approximately 10
seconds between the gas change and the when
it is restored).
The restored values will be those relating to the
type of boiler set in parameters “n” and “F”.
At the end of this operation, anomaly “E62” will
appear and complete calibration will be required.
-
Menu “G”. This menu is reserved for the air-gas
control settings and it features two sub-menus
(n and S), relating to fan and gas valve control
settings. Every time these parameters are al-
tered, the complete calibration function must
be activated (see par. 3.8). In order to access
parameters “n” and “S” press the “Reset” button
sequentially. In order to exit this part of the
menu and access other parts (categories P, t,
A, F) press the “Summer / winter” button.
