Sliding Temperature
When the external probe (optional) is installed, the boiler adjustment system works with "Sliding Temperature". In this
mode, the heating system temperature is regulated according to weather conditions, to ensure high comfort and energy
efficiency throughout the year. In particular, as the outside temperature increases the system flow temperature decrea-
ses according to a specific "compensation curve".
With "Sliding Temperature", the temperature set using the heating buttons (details 3 and 4 - fig. 1) becomes the maxi-
mum system flow 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. However, the user can make any further
adjustments necessary to optimize comfort levels.
