• 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 se-
lected bend of the K coefficient in Fig. 7.16
(the value read on the display corresponds
to K coefficients decimal values).
The writing

alternates on the dis-
play (Fig. 7.20).

• By pressing key 12 (Fig. 7.17) confirmation
of the inserted value is obtained.
• Press keys 15 or 16 (Fig. 7.17) to exit with-
out changing the value Fig. 7.19)
• Exiting the “programming mode” is auto-
matic, after 15 minutes, or by cutting power.
At this point the plant flow temperature will fol-
low the trend in relation to the K coefficient set.
However, if the ambient temperature is not
comfortable, the flow temperature of the heat-
ing plant can be increased or reduced by ±
15°C by acting on keys 15 (reduce) and 16
(increase) (Fig. 7.17).

• Electrically feed the boiler by activating the
bipolar switch envisioned during installation.
