Room temperature adjustment (with optional room thermostat)

Using the room thermostat, set the temperature desired in the rooms. If the room ther-
mostat 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 according to the required room temperature. For information on
the remote timer control, please refer to its user's manual.

Sliding temperature

When the optional external probe is installed, the control panel display (detail 5 - fig. 1)
shows the actual outside temperature read by the probe. The boiler control system works
with "Sliding Temperature". In this mode, the heating system temperature is controlled
according to the outside weather conditions in order to ensure high comfort and energy
saving throughout the year. In particular, as the outside temperature increases the sys-
tem delivery temperature decreases according to a specific "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 advis-

able 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. Adjust-
ments can in any case be made by the user to improve comfort .

Press the

mode

button (detail 10 - fig. 1) once to display the actual compensation curve

(fig. 11) which can be modified with the

order curve and vice versa. Proceed by increasing or decreasing in steps of one and
check the result in the room.
