ture from a min. of 10°C to a max. of 65°C.

the remote timer control, please refer to its user's manual.
Sliding Temperature
When the optional external probe is installed the control panel display (detail 5 - fig. 1)
shows the actual outside temperature read by the probe. The boiler control system op-
erates with "Sliding Temperature". In this mode, the temperature of the heating system
is controlled according to the outside weather conditions, to ensure high comfort and en-
ergy saving throughout the year. In particular, as the outside temperature increases the
system delivery temperature decreases according to a specific "compensation curve".
With Sliding Temperature adjustment, the temperature set with the heating buttons
(details 3 and 4 - fig. 1) becomes the maximum system delivery tempera-
ture. It is advisable to set the maximum value to allow system adjustment throughout its
useful operating range.
The boiler must be adjusted at the time of installation by qualified personnel. Adjust-
ments can in any case be made by the user to improve comfort.
