• Press keys 14 and 16 (Fig. 7.17) at the
same time until the value of parameter 15
(Fig. 7.20) is displayed on the LCD dis-
play.

• Using keys 15 or 16 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. 7.16 (the value read on the display
corresponds to K coefficients decimal val-
ues).
• By pressing key 14 (Fig. 7.17) confirma-
tion of the inserted value is obtained.
• Press keys 14 and 15 (Fig. 7.17) at the
same time to exit without changing the
value (return to the parameters list Fig.
7.19).
• Press keys 14 - 15 - 16 (Fig. 7.17) at the
same time for 10 seconds to exit the "pro-
gramming mode".
At this point the plant flow temperature will
follow the trend in relation to the K coeffi-
cient set.
However, if the ambient temperature is not
comfortable, the flow temperature of the
heating plant can be increased or reduced
by ± 15°C by acting on keys 15 (reduce)
and 16 (increase) (Fig. 7.17).

Act on the programming of the REMOTE
control to select the setting of the K coef-

• Electrically feed the boiler by activating
the bipolar switch envisioned during in-
stallation.
• Press button for more than 3 seconds to
enter in
(Fig. 7.22) mode.
