is possible to modify the value of parameter
P07:
00 = probe disabled (preset)
01 = probe enabled
• Press 11 or 12 (Figure 5.44) to confirm the
value entered and return to the list of param-
eters Figure 5.46.
• Press the 16 button (Figure 5.44) to exit
"programming mode".
• Press 12 and hold until the LCD display
shows the code P08, indicating entry into
"parameter P08" (Figure 5.48).

• Using buttons 14 or 15 it is possible to
change the value of parameter P08 from a
minimum of 1.0 to a maximum of 3.0 based
on the selected curve of the K coefficient in
Figure 5.42 (the value read on the display
corresponds to the decimal values of the K
coefficients).
• Press 11 or 12 (Figure 5.44) to confirm the
value entered and return to the list of param-
eters (Figure 5.48).
• Press the 16 button (Figure 5.44) to exit
"programming mode".
At this point the system delivery temperature
will follow the trend in relation to the set K co-
efficient.
If the room temperature is not comfortable,
you can increase or decrease the heating
system delivery temperature by ± 5°C using
the 14 (decrease) and 15 (increase) buttons
(Figure 5.44).

5.19 Selecting the maximum heating
temperature setpoint with the cli-
matic curve set
Depending on the type of high or low tempera-
ture heating system, the maximum climatic
curve temperature can be set.
In heating mode, the boiler is set for a tem-
perature range of between a minimum of 50°C
and a maximum of 80°C (high temperature) or
a minimum of 27°C and a maximum of 55°C
