10,07 Outside temperature compensation
When the (optional) external probe is installed, the boiler regulation system functions in “Outside temperature
compensation” mode. In this mode, the temperature of the heating system is regulated according to the
external climatic conditions, so as to guarantee a high degree of comfort and energy saving all year round.
Specifi cally, when the external temperature falls, the central heating outlet temperature is increased, according
to a pre-determined “compensation curve”.
In this mode, the temperature set in parameter 1 of the operating menu becomes the maximum central
heatin g outlet temperature. This should be set to Maximum to allow the system to regulate over the
entire working range.
The boiler must be set during installation by qualifi ed personnel. Other minor modifi cations can be made by the user
to improve the level of comfort: the compensation curve can in fact be modifi ed by accessing the operating menu
with the button
and scrolling the menu, again using the button, to parameter 9.
The set compensation curve is displayed (refer to graph below). Pressing one of the buttons
the display
starts to fl ash; use the buttons
to set the required value. To activate the new curve, press the button
.
To cancel the setting, do not press the
button, and press the button
.
If the ambient temperature is lower than the required value, it is suggested to set a higher curve, and vice-versa.
Proceed with single unit increments or decreases, and check the results in the room.

10.08 Maintenance
It is strongly recommended to effect the annual maintenance of the heating system and at least biennial checks of
the combustion device. Please refer to the “maintenance” section in this manual.
The casing, the control panel and the aesthetic parts of the boiler can be cleaned using a soft and damp
cloth. Do not use abrasives or solvents.
10.09 Anomalies
In the event of operating anomalies or problems, the display fl ashes and shows the code identifying
the anomaly.
The anomalies marked by the letter
“F”
cause temporary shut-down, and are reset automatically as soon as the
value returns within the boiler’s normal operating range.
The anomalies marked by the letter
“A”
cause a shut-down of the boiler which can be reset by the user. To
reset operation, press the
(reset) button.
If the problem persists, or for any other anomalies, please refer to the “troubleshooting” chapter in this
manual for more details.
