Room temperature adjustment (with optional room thermostat)
Using the room thermostat, set the temperature desired in the rooms. If the room thermostat is not installed the boiler
will keep the heating system at its setpoint temperature.

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.
ECO/COMFORT selection
The unit is equipped with a function that ensures a high domestic hot water delivery speed and maximum comfort for
the user. When the device is activated (COMFORT mode), the water contained in the boiler is kept hot, therefore en-
suring immediate availability of hot water from the boiler on opening the tap, thus avoiding waiting times.
The device can be deactivated by the user (ECO mode) by turning the selector (detail 3 - fig. 1) to the RESET position
for 2 seconds and then to
(winter) or
(summer). To activate COMFORT mode, turn the selector (detail 3 - fig. 1)
to RESET again for 2 seconds and then to
(winter) or
(summer).
Sliding temperature
When the optional outdoor sensor is installed, the boiler adjustment system works with "Sliding Temperature". In this
mode, the temperature of the heating system is adjusted according 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 decreases according to a determinate "compensation curve".
With the Sliding Temperature adjustment, the temperature set with the heating knob (detail 1 - fig. 1) becomes the max-
imum system delivery 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. Possible adjustments can in any case be
made by the user to improve comfort.
