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.
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 temperature of the heating system
is adjusted according the outside weather conditions, in order to ensure high comfort and
energy saving throughout the year. In particular, as the outside temperature increases,
the system delivery temperature is decreased according to a specific "compensation
curve".
With Sliding Temperature adjustment, the temperature set with the heating buttons
(details 3 and 4 - fig. 1) becomes the maximum system delivery tempera-
ture. 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 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 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.
