Adjusting the C.H. temperature with the
external temp. probe installed

is installed your boiler automatically adjusts

ified installer (see "Setting the K coefficient
of the external temperature probe" on page
62).
However, if the ambient temperature is not
comfortable, the flow temperature of the
heating system can be adjusted by ± 15°C
by acting on keys 10 (reduce) and 11 (in-
crease) (Fig. 2.3).
