3.13 P.C.B. PROGRAMMING
The boiler is prepared for possible programming of several opera-
tion parameters.
By modifying these parameters as described below, the boiler can
be adapted according to specific needs.
54
To access the programming
phase, press and hold the but-
tons “ ” and “ ” for
more than 5 seconds, the dis-
play shows two dashes “--”
flashing.
55
Now enter the password “69” to
access the parameter menu.
To enter the first digit, use the
buttons to adjust the D.H.W.
“ ”; to enter the second dig-
it, use the buttons to adjust the
central heating temperature “
”.
56
To confirm the password “69”
and access the menu, press the “
”.
57
Once in the menu, you can cy-
clically scroll the submenus by
pressing the D.H.W. buttons
“ ”, to access the menu
press the button “ ”.
58
The first digit of the central in-
dicator ( ) shows the family
of the parameter.
The second digit shows the pa-
rameter number.
Press the “ ” button to display
the value of the selected param-
eter.
59
Its value can be adjusted by
using the central heating tem-
perature adjustment buttons “
”.
60
Press the mode of operation
button “ ” for more than 1
second to store the parameter
value; confirmation is given by
the word “ ” which appears
for 2 seconds.
If you want to exit a parameter
without changing its value,
press the button “ ”.
Exit the programming mode by
waiting 15 minutes or by press-
ing the
“ ” button until you return
to the desired display.
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 ac-
cording to the actual operating conditions (wait for ap-
proximately 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 com-
plete calibration will be required.
Menus “G” - “S” - “n”.
These menus are reserved for air-gas control settings.
Every time these parameters are altered, the complete calibration
function must be activated (Par. 3.9).
