In this case K setting must be done from the
remote control.

The K coefficients is a parameter that increas-
es or reduces the boiler flow temperature
when the outside temperature changes.
When installing the external probe it is nec-
essary to set this parameter based on the ef-
ficiency of the heating system in order to opti-
mise 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 tem-
perature of -5°C, set a K at 1.5 (sectioned line
in Fig. 8.6).

Sequence for setting the K coefficient
• Enter in "programming mode" by sequen-
tially pressing and holding keys 13 - 16 - 17
(Fig. 8.7) for 10 seconds at the same time
until the letters P01 are displayed on the
LCD display, indicating that "parameter 01,
has been activated (Fig. 8.8).

• Scroll the various parameters using keys 16
or 17 until the letters P15 are displayed on
the LCD display, indicating that "parameter
15" (Fig. 8.9) has been activated.

• Using keys 16 or 17 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. 8.6
(the value read on the display corresponds
to K coefficients decimal values).
