Sliding Temperature

When the optional external probe is installed, the boiler adjustment system works 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 energy saving

throughout the year. In particular, the system delivery temperature is decreased as the

outside temperature increases, according to a specific "compensation curve”.
With Sliding Temperature adjustment, the temperature set with the heating buttons (de-

tail 3 - fig. 1) becomes the maximum system delivery temperature. It is advisable to set

a maximum value to allow system adjustment throughout its useful operating range.
The boiler must be adjusted at the time of installation by qualified personnel. Possible

adjustments can in any case be made by the user to improve comfort.
