Sliding Temperature
When the optional external probe is installed the corresponding symbol (detail 22 fig. 1)
is activated on the control panel display (detail 5 - fig. 1). The boiler control system op-
erates with "Sliding Temperature". In this mode, the heating system temperature is con-
trolled according to the outside weather conditions, in order to ensure high comfort and
energy saving throughout the year. In particular, the system delivery temperature is de-
creased as the outside temperature increases, according to a specific "compensation
curve".
With Sliding Temperature adjustment, the temperature set with the heating buttons
(details 3 and 4 - fig. 1) becomes the maximum system delivery temper-
ature. 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.
