(with optional hot water tank installed).

Using the remote timer control, set the temperature desired in the rooms. The boiler unit will set the system water ac-
cording to the required room temperature. For information on the remote timer control, please refer to its user's manual.
Sliding Temperature
When the external probe (optional) is installed, the relevant external temperature symbol is activated on the control pa-
nel display. The boiler control system works with "Sliding Temperature". In this mode, the heating system temperature
is regulated according to weather conditions, to ensure high comfort and energy efficiency throughout the year. In par-
ticular, as the outside temperature increases the system flow temperature decreases according to a specific "compen-
sation curve".
With Sliding Temperature adjustment, the "Heating adjustment" temperature becomes the maximum system flow tem-
perature. 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. The user can still make further adjustments
for better comfort.
Compensation curve and curve offset
Access the Sliding Temperature menu. Adjust the
desired curve from 1 to 10 according to the characte-
ristic (fig. 30) via the parameter "Curve1" and confirm
with the OK button.
By setting the curve to 0, the sliding temperature ad-
justment is disabled.
