Room temperature adjustment (with optional room thermostat)
Using the room thermostat, set the temperature desired in the rooms. If the room thermostat 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.
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 works with "Sliding Tem-
perature". In this mode, the heating system temperature is controlled according to the outside
weather conditions in order to ensure high comfort and energy saving throughout the year. In par-
ticular, as the outside temperature increases the system delivery temperature decreases accord-
ing to a specific "compensation curve".
With Sliding Temperature adjustment, the temperature set with the heating buttons (details3 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 adjusted at the time of installation by qualified personnel. Adjustments can in
any case be made by the user to improve comfort .
Compensation curve and curve offset
Press the mode button (detail 10 - fig. 1) once to display the actual compensation curve
(fig. 11) 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. 13).
By setting the curve to 0, sliding temperature adjustment is disabled.
fig. 11 - Compensation curve
Press the heating buttons (details 3 and 4 - fig. 1) to access parallel curve offset
(fig. 14), modifiable with the DHW buttons (details 1 and 2 - fig. 1).
fig. 12 - Curve parallel offset
Press the mode button (detail 10 - fig. 1) again to exit the parallel curve adjustment
mode.
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.
