Adjusting the C.H. temperature with the
external temp. probe installed
When the external temp. probe (optional)
is installed your boiler automatically adjusts
the temperature of the C.H. system water
flow in relation to the external temperature.
In this case the boiler must be set by a qual -
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 pressing on keys 15 (reduce) and 16 (in -
crease) (Fig. 2.9).
2.5 D.H.W. temperature
The temperature of the D.H.W. can be ad -
justed by pressing keys 12 (increase) and
13 (reduce) (Fig. 2.9) from a minimum of
about 30°C to a maximum of about 60°C.
Press one of the two keys once to display
the "set" value. Press again to access the
modification.

Adjustment
Adjust the D.H.W. temperature to a value
suited to your needs.
Reduce the necessity of mixing hot water
with cold water.
In this way, the automatic adjustment fea -
tures will be appreciated.
If water hardness is particularly high, we
recommend that the boiler be adjusted to a
temperature of less than 50°C.
However in these cases we recommend
that a softener is installed on the domestic
cold feed.
D.H.W. request
When the boiler has a power request in the
D.H.W. mode, the symbol is displayed
on the display followed by an increase of
the heating water flow temperature. The
symbol flashes (Fig. 2.14).
