Heating temperature adjustment
Use the heating buttons (details 3 and 4 - fig. 1) to ad-
just 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 thermostat 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 ac-
cording to the required room temperature. For operation with remote timer control, please refer to the relevant instruc-
tion manual.
ECO/COMFORT selection
The unit has a function that ensures fast hot water delivery and maximum comfort for the user. When the device is ac-
tivated (COMFORT mode), the water contained in the boiler is kept hot, thereby ensuring immediate availability of hot
water by turning the faucet on, without waiting times.
The device can be deactivated by the user (ECO mode) by briefly pressing the off 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 off button again
(detail 7 - fig. 1).
Sliding Temperature
When the external probe (optional) is installed, the boiler adjustment system works with "Sliding Temperature". In this
mode, the heating system temperature is regulated according to weather conditions, to ensure high comfort and energy
efficiency throughout the year. In particular, as the outside temperature increases the system flow temperature decrea-
ses according to a specific "compensation curve".
With the Sliding Temperature adjustment, the temperature set with the heating buttons (details 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. The user can still make further adjustments
for better comfort.
Compensation curve and curve offset
Pressing 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).
