Hot water 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 desired in the rooms. If the room ther-
mostat is not installed the boiler will keep the heating system at its setpoint temperature.
Room temperature adjustment (with optional remote timer control)
Using the remote timer control, set the temperature desired in the rooms. The boiler unit
will set the system water according to the required room temperature. For information on
the remote timer control, please refer to its user's 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, therefore ensuring immediate availability of hot water
on opening the tap, without waiting times.
The device can be deactivated by the user (ECO mode) by pressing the eco/comfort
button (detail 7 - 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 control panel display (detail 5 - fig. 1)
shows the actual outside temperature read by the probe. The boiler control system op-
erates with "Sliding Temperature". In this mode, the heating system temperature is ad-
justed according to the outside weather conditions in order to ensure high comfort and
energy efficiency throughout the year. In particular, as the outside temperature increas-
es, the system delivery temperature decreases according to a specific "compensation
curve".
With Sliding Temperature adjustment, the temperature set with the heating buttons (de-
tails 3 and 4 - 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 regulated 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 button (detail 10 - fig. 1) once to display the compensation curve (fig. 12),
which can be modified with the DHW buttons (details 1 and 2 - fig. 1).
Adjust the required curve from 1 to 10 according to the characteristic (fig. 14).
By setting the curve to 0, sliding temperature adjustment is disabled.
fig. 12 - Compensation curve
Press the heating buttons (details 3 and 4 - fig. 1) to access parallel curve offset (fig. 15),
modifiable with the DHW buttons (details 1 and 2 - fig. 1).
