2. Parameters with more than one description are reset to the default value if the parameter given
in brackets is modified.
3. The Maximum Heating Power parameter can also be modified in Test Mode.
To return to the service menu, simply touch the "arrow" icon
in the top left corner of the screen.

ONLY QUALIFIED PERSONNEL CAN ACCESS THE MENU AND MODIFY THE RELEVANT
PARAMETERS.
ZTP (Sliding temperature) Parameters Menu
When the external probe is installed, the boiler adjustment system works with "Sliding Tempera-
ture". In this mode, the heating system temperature is regulated according to weather conditions,
to ensure high comfort and energy efficiency throughout the year. In particular, as the outside tem-
perature increases the system flow temperature decreases according to a specific "compensation
curve".
With Sliding Temperature adjustment, the temperature set using the buttons [+] (detail 12 fig.1)
and [-] (detail 14 fig.1) becomes the maximum system flow 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. However, the user
can make any further adjustments necessary to optimize comfort levels.
Compensation curve and curve offset
The settings of the compensation curves and relevant offset can be accessed via the service
menu and touching the item [ZTP parameters]. Use fig. 25 as a reference for choosing the value
of curve-type parameters and fig. 26 as a reference for choosing the value of offset-type parame-
ters.
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.
