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 decreases according to a specific
"compensation curve".
With "Sliding Temperature", the temperature set using the heating buttons (details 3 and 4 -
fig. 1) becomes the maximum 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.
