is activated on the control panel display (detail 5 - fig. 1). The boiler control system works
with "Sliding Temperature". In this mode, the heating system temperature is controlled
according to the outside weather conditions in order to ensure high comfort and energy
saving throughout the year. In particular, as the outside temperature increases, the sys-
tem delivery temperature is decreased according to a specific "compensation curve".
With Sliding Temperature adjustment, the temperature set with the heating buttons
3 and 4 - fig. 1) becomes the maximum system delivery temperature. It is advis-
