7.10 Setting the K coefficient of the
external temperature probe
The boiler is set with a K coefficient equal to
zero for boiler functioning without the probe
connected.
If the boiler is NOT EQUIPPED with the re-
mote control (optional) refer to Fig. 7.18.

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 neces-
sary to set this parameter based on the effi-
ciency of the heating plant in order to optimise
the flow temperature (Fig. 7.19).
E.g. In order to have a flow temperature at the
heating plant of 60°C with an external tem-
perature of -5°C, set a K at 1.5 (sectioned line
in Fig. 7.19).
