Sliding temperature
When an external probe (optional) is installed, the corresponding symbol of the outside temperature is activated on the
control panel display. The boiler adjustment system works with "Sliding Temperature". In this mode, the temperature of
the heating system is adjusted according to the outside weather conditions, to ensure a high level of comfort and energy
saving throughout the year. In particular, as the outside temperature increases, the system delivery temperature de-
creases according to a specific "compensation curve".
With Sliding Temperature adjustment, the "Heating adjustment" temperature 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. Adjustments can in any case be made by
the user to improve comfort.
Compensation curve and curve offset
Access the Sliding Temperature menu. Adjust the required curve from 1 to 10 according to the characteristic (fig. 28)
through the parameter "Curve1" and confirm with the OK button.
By setting the curve to 0, the sliding temperature adjustment is disabled.
Adjust the parallel offset of the curves from 20 to 60 °C (fig. 29), through the parameter "Offset1" and confirm with the
OK button.
