2.4 Adjustments
Summer/Winter Switchover
Press the summer/winter button (detail 6 - fig. 1) for 1 second.
The display activates the Summer symbol (detail 27 - 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 (part. 6 - fig. 1) again
for 1 second.
Heating temperature setting
Use the heating buttons
from a min. of 30°C to a max. of 80°C.
DHW temperature adjustment
Use the DHW buttons
from a min. of 10°C to a max. of 65°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.
Sliding Temperature
When the optional external probe is installed, the control panel display (detail 5 - fig. 1)
shows the actual outside temperature detected by the external probe. The boiler control
system operates with "Sliding Temperature". In this mode, the heating system tempera-
ture is controlled according to the outside weather conditions in order to ensure high
comfort and energy efficiency throughout the year. In particular, as the outside temper-
ature increases the system delivery temperature decreases according to a specific "com-
pensation curve".
With Sliding Temperature adjustment, the temperature set with the heating buttons
(detail 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 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 mode button (detail 10 - fig. 1) once to display the compensation curve (fig. 9)
which can be modified with the DHW buttons
Adjust the required curve from 1 to 10 according to the characteristic (fig. 11).
By setting the curve to 0, sliding temperature adjustment is disabled.

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.

Adjustments from Remote Timer Control
A
If the Remote Timer Control (optional) is connected to the boiler, the above ad-
justments are managed according to that given in table 1. Also, the control pan-
el display (detail 5 - fig. 1) shows the actual room temperature detected by the
Remote Timer Control.
Table. 1
Heating temperature setting Adjustment can be made from the Remote Timer Control menu and the boiler
control panel.
DHW temperature adjustment Adjustment can be made from the Remote Timer Control menu and the boiler
control panel.
Summer/Winter Switchover Summer mode has priority over a possible Remote Timer Control heating
demand.
On disabling DHW from the Remote Timer Control menu, the boiler selects the
Economy mode. In this condition, the button 7 - fig. 1 on the boiler panel is dis-
abled.
Eco/Comfort selection
On enabling DHW from the Remote Timer Control menu, the boiler selects the
Comfort mode. In this condition it is possible select one of the two modes with
the button 7 - fig. 1 on the boiler panel.
Sliding Temperature Both the Remote Timer Control and the boiler card manage Sliding Temperature
adjustment: of the two, the Sliding Temperature of the boiler card has priority.
Water system pressure adjustment
The filling pressure with system cold, read on the display, must be approx. 1.0 bar. If the
system pressure falls to values below minimum, the boiler card will activate fault F37
(fig. 13).
fig. 13 - Low system pressure fault

Once the system pressure is restored, the boiler will activate the 120-second
air venting cycle indicated on the display by FH.
