3.8 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.
Attention:
If the international language is to be
restored (A1) see the indications described in
Par. 2.7 (Customisations menu - M3).
By pressing the button "D" it is possible to access
the main menu, divided into three main parts:
- Information“M1” (See “User” Chapter)
- customisations “M3” (See “User” Chapter)
- “M5” configurations, menu reserved for the
technician and for which a password is required.
To access programming, press button “D”, turn
the central heating temperature selector switch
(3) and scroll through the menu items until
reaching “M5”, press button “D”, enter the pass-
word and set the parameters according to your
requirements.
Listed below are the items in the“M5” menu
with default parameters and possible options
indicated.
By turning the central heating temperature se-
lector switch (3) scroll through the menu items.
By pressing button “D” access the various levels
of the menu and the choice of parameters is
confirmed. Press button “C” to go back one level.
(The first item of the various options that appears
inside the parameter is that selected by default).

Note:
after selecting DELTA T adequate to the requirements, maximum (Vmax)
and minimum (Vmin) circulating pump speed may be selected (adjustable from
100% to 75%).

Fixed circulator pump speed (adjustable between 100% and 75%)
P62 4000 ÷ 5900
Set the maximum output depending on the domestic hot water, setting the speed
of the fan (in RPM)
(See par. 3.5)
P63 900 ÷ 1500
Set the minimum output depending on the domestic hot water, setting the speed
of the fan (in RPM)
(See par. 3.5)
P64 ≤ P62
Set the maximum output depending on room heating. The value must be less
than or equal to P62
(See par. 3.5)
P65 ≥ P63
Set the minimum output according to room heating. The value must be greater
than or equal to P63
(See par. 3.5)
P66
P66/A
Without the external probe (optional) it defines the minimum flow temperature.
With the external probe present it defines the minimum flow temperature corre-
sponding to operation with maximum external temperature (see graph Fig. 1-7)
(it can be set between 20°C and 50°C)
N.B.: to continue one must confirm the parameter (press “D” or exit adjustment
“P66” by pressing “C”)
20°C
P66/B
Without the external probe (optional) it defines the maximum flow tempera-
ture. With the external probe present it defines the maximum flow temperature
corresponding to operation with minimum external temperature (see graph Fig.
1-7) (it can be set between 50°C and 85°C)
N.B.: to continue one must confirm the parameter (press “D” or exit adjustment
“P66” by pressing “C”)
85°C
P66/C
With the external probe present it defines at which minimum external tempera-
ture the boiler must operate at the maximum flow temperature (see graph Fig.
1-7) (can be set between -20°C and 0°C)
N.B.: to continue one must confirm the parameter (press “D” or exit adjustment
“P66” by pressing “C”)
-5°C
P66/D
With the external probe present it defines at which maximum external tempera-
ture the boiler must operate at the minimum flow temperature (see graph Fig.
1-7) (can be set between 5°C and +25°C)
N.B.: to continue one must confirm the parameter (press “D” or exit adjustment
“P66” by pressing “C”)
25°C
