If the boiler is EQUIPED with the remote
control (optional) refer to Fig. 8.6.
In this case K setting must be done from the
remote control.

The K coefficients is a parameter that in-
creases or reduces the boiler flow tempera-
ture when the outside temperature changes.
When installing the external probe it is nec-
essary to set this parameter based on the
efficiency of the heating system in order to
optimise the flow temperature (Fig. 8.6).
E.g. In order to have a flow temperature at
the heating system of 60°C with an external
temperature of -5°C, set a K at 1.5 (sec-
tioned line in Fig. 8.6).

Sequence for setting the K coefficient
• Enter in "programming mode" by sequen-
tially pressing and holding keys 9 - 10 - 11
(Fig. 8.7) for 10 seconds at the same time
until the letters Pr that alternate with code
01 are displayed on the LCD display, indi-
cating that "parameter 01, has been acti-
vated (Fig. 8.8).

• Scroll the various parameters using keys
10 or 11 until the letters Pr that alternate
with code 15 are displayed on the LCD
display, indicating that "parameter 15"
(Fig. 8.9) has been activated.
