fig. 7 - Turning the boiler off
When the boiler is turned off, the PCB is still powered. Domestic hot water and heating
are disabled. The frost protection system remains activated. To relight the boiler, press
the On/Off button (detail 7 - fig. 1) again for 5 seconds.
The boiler will be immediately ready to operate whenever domestic hot water is drawn
or in case of a room thermostat demand.

The frost protection system does not work when the power and/or gas to the
unit are turned off. To avoid damage caused by freezing during long shutdowns
in winter, it is advisable to drain all water from the boiler, the DHW circuit and
the heating system water; or drain just the DHW circuit and add a suitable an-
tifreeze to the heating system, as prescribed in sec. 3.3.
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
20°C to a max. of 80°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.
B
If little water is drawn and/or with a high water inlet temperature, the DHW
outlet temperature may differ from the set temperature.
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 temperature of the heating system is controlled according to the
outside weather conditions, to ensure high comfort and energy saving throughout the year. In par-
ticular, the system delivery temperature is decreased as the outside temperature increases, ac-
cording to a specific "compensation curve".
With 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. Possible adjustments
can in any case be made by the user to improve comfort.
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 curve from 1 to 10 according to the character-
istic fig. 11. By setting the curve to 0, 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 the parallel curve offset according to the
characteristic (fig. 12).
Press the reset button (detail 6 - fig. 1) again for 5 seconds to exit the "Sliding Temperature"
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.
