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.
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 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 on opening the tap, without waiting times.
The device can be deactivated by the user (ECO mode) by pressing the button (detail 7 -
fig. 1
). In ECO mode the display
activates the ECO symbol (detail 12 -
fig. 1
). To activate COMFORT mode, press the button (detail 7 -
fig. 1
) again.
Sliding temperature
When the optional external probe is installed the boiler adjustment system works with "Sliding Temperature”. In this
mode, the temperature of the heating system is adjusted according to the outside weather conditions, in order to ensure
high comfort and energy saving throughout the year. As the outside temperature increases, the temperature of the heat-
ing system is decreased according to a fixed “compensation curve”.
With Sliding Temperature adjustment, the temperature set with the heating buttons (details 3 and 4 - fig. 1)
becomes the maximum 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.
Compensation curve and curve offset
Press the button (detail 6 -
fig. 1
) for 5 seconds to access the "Sliding temperature" menu; "CU" appears flashing (
fig. 11
).
Operate the DHW buttons (details 1 and 2 - fig. 1) to adjust the required curve from 1 to 10 according to the
characteristic (fig. 13). By setting the curve to 0, sliding temperature adjustment is disabled.
