ECO/COMFORT selection
The unit has a function that ensures a high domestic hot water delivery speed and max-
imum comfort for the user. When the device is activated (COMFORT mode), the water
contained in the boiler is kept hot, thereby ensuring immediate availability of hot water
on opening the tap, thus avoiding waiting times.
The device can be deactivated by the user (ECO mode) by pressing the reset button (de-
tail 3 - fig. 1). The Comfort symbol (detail 8 - fig. 1) will be deactivated and the display
will show "EC" (ECO) for 3 seconds.
To activate the COMFORT mode, press the reset button (detail 3 - fig. 1). The Comfort
symbol (detail 8 - fig. 1) will be activated and the display will show "CO" (COMFORT) for
3 seconds.
Sliding Temperature
When the optional external probe is installed the boiler adjustment system works with
"Sliding Temperature". In this mode, the heating system temperature is regulated ac-
100
cording to weather conditions, to ensure the high comfort and energy efficiency through-
120
out the year. In particular, as the outside temperature increases the system delivery
temperature decreases according to a specific "compensation curve".
With the Sliding Temperature adjustment, the temperature set with the heating knob (de-
tail 3 - fig. 1) 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. However,
the user can make any further adjustments necessary to optimise comfort levels.
