Sliding Temperature - Compensation Curve
By installing the external probe (optional), the control system can work with a Sliding Temperature. The
external probe must be connected to the boiler card: refer to the relevant handbook for details. In this mode,
the heating system temperature is adjusted according to the outside weather conditions in order to ensure
high comfort and energy saving throughout the year. In particular, as the external temperature increases
the system delivery temperature decreases according to a specific compensation
curve. With the Sliding
Temperature adjustment the temperature set through the “Heating temperature adjustment” setting beco-
mes the maximum system delivery temperature. It is advisable to set a maximum value to allow system
adjustment throughout its useful operating range.
The compensation curve can be set from 1 to 10
according to the following graph.

Once the Compensation curve has been set, parallel curve offset can be adjusted from 20 to 40 as shown
in the following graphs:
The system 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. If the room temperature is lower than the required value,
it is advisable to set a higher order curve and vice versa. Proceed by increasing or decreasing in steps of
