• Press keys 9 and 11 (Fig. 8.7) at the same
time until the value of parameter 15 (Fig.
8.10) is displayed on the LCD display.

• Using keys 10 or 11 it is possible to
change the value of parameter 15 from a
minimum of 01 to a maximum of 60 based
on the selected bend of the K coefficient
in Fig. 8.6 (the value read on the display
corresponds to K coefficients decimal val-
ues).
• By pressing key 9 (Fig. 8.7) confirmation
of the inserted value is obtained.
• Press keys 9 and 10 (Fig. 8.7) at the same
time to exit without changing the value (re-
turn to the parameters list Fig. 8.9).
• Press sequentially keys, 9 - 10 and then
11 (Fig. 8.7) and hold in for 10 seconds to
exit the "programming mode".
At this point the system flow temperature
will follow the trend in relation to the K coef-
ficient set.

However, if the ambient temperature is not
comfortable, the flow temperature of the
heating system can be increased or re-
duced by ± 15°C by pressing keys 10 (re-
duce) and 11 (increase) (Fig. 8.7).
