2.4 Adjustments
Summer/Winter Switchover
Press the summer/winter button (detail 6 - fig. 1) for 2 seconds.
The display activates the Summer symbol (detail 10 - fig. 1): the boiler will only deliver
domestic hot water. The antifreeze system remains activated.
To deactivate the Summer mode, press the summer/winter button (detail 6 - fig. 1)
again for 2 seconds.
Heating temperature adjustment
Use the heating buttons (details 3 and 4 - fig. 1) to adjust the temperature from a min. of
30°C to a max. of 80°C; in any case, it is advisable not to operate the boiler below 45°C.
DHW temperature adjustment
Use the DHW buttons (details 1 and 2 - fig. 1) to adjust the temperature from a min. of
40°C to a max. of 55°C.
Room temperature adjustment (with optional room thermostat)
Using the room thermostat, set the temperature required in the rooms. If the room ther-
mostat is not installed, the boiler will keep the system at the set system delivery setpoint
temperature.
Room temperature adjustment (with optional remote timer control)
Using the remote timer control, set the required temperature in the rooms. The boiler will
adjust the system water according to the required room temperature. For operation with
remote timer control, please refer to the relevant instruction manual.
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, without waiting times.
The user can deactivate the device (ECO mode) by pressing the eco/comfort button
(detail 7 - fig. 1). In ECO mode the display activates the ECO symbol (detail 12 - fig. 1).
To activate the COMFORT mode, press the eco/comfort button (detail 7 - fig. 1) again.
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-
cording to weather conditions, to ensure the high comfort and energy efficiency through-
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 buttons
(detail 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.
Compensation curve and curve offset
Press the reset button (detail 6 - fig. 1) for 5 seconds to access the "Sliding temperature"
menu; the display shows "CU" flashing.
Use the DHW buttons (detail 1 - fig. 1) to adjust the desired curve from 1 to 10 according
to the characteristic (fig. 6). By setting the curve to 0, the sliding temperature adjustment
is disabled.
Press the heating buttons (detail 3 - fig. 1) to access parallel curve offset; the display
shows "OF" flashing. Use the DHW buttons (detail 1 - fig. 1) to adjust parallel curve offset
according to the characteristic (fig. 7).

Press the reset button (detail 6 - fig. 1) again for 5 seconds to exit the "Sliding Temper-
ature" menu.
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 one and
check the result in the room.

System water pressure adjustment
The filling pressure read on the boiler water gauge (detail 2 - fig. 8) with system cold must
be approx 1.0 bar. If the system pressure falls below minimum values, the boiler stops
and fault F37 is displayed. Pull out the filling knob (detail 1 - fig. 8) and turn it anticlock-
wise to return it to the initial value. Always close it afterwards.
Once the system pressure is restored, the boiler will activate the 300-second air venting
cycle indicated on the display by Fh.
To prevent boiler shutdown, it is advisable to periodically check the pressure on the
gauge with system cold. In case of a pressure below 0.8 bar, it is advisable to restore it.
