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
50).
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 13 (reduce) and 14 (in-
crease) (Fig. 2.7).
