this lapse of time the set value can be changed by pressing
the “+/-” buttons.
TO ADJUST THE HEATING SYSTEM
Plus and Minus buttons (+/-) of the control panel (4, 6).
They change the temperature value of primary water sent
directly (without SE) or indirectly (with SE) to the radiators.
Without SE.
When the SE external probe is not connected or has been
disabled from its switch, the “+/-” buttons change the
supplied water temperature value within the 40 - 80°C
range.
Press the “+/-” button once: the set Tm value is displayed.
The value is displayed for 5": during this lapse of time the
set value can be changed by pressing the “+/-” buttons.
The heating system operates according to the fixed
reference value of the supplied water temperature Tm.
With SE (optional, on pre-set boilers).
To benefit from the climatic function, and consequently
from a better adaptation of the equipment to the heating
needs of the room, an external temperature probe must
be installed (SE), This probe is supplied on request. As for
the installation and the electrical connection of the SE,
please see the booklet of boiler. The trigger box detects
the presence of an external probe and starts working on
climatic mode. The temperature of delivery varies as a
function of the external temperature following a curve which
is set up (out?) by two parameters. These parameters can
be inserted by the buttons + and – for the regulation of
the heating (see diagram):
1) Water delivery temperature (Tm1) requested when
the external temperature (Te) is higher than 15°C
2) Water delivery temperature (Tm2) requested
when Te is lower than 0° C.
When the heating regulation buttons are pressed the actual
value of Tm1 will be shown ????? non capisco l’italiano.
After few seconds two hyphens will appear on the display.
Once this occurs the value of Tm2 will have to be inserted.
Tm1 and Tm2 must always be comprised between 0 and
80° C, Tm1 ≤ Tm2.
When the external probe is present the climatic function
can also be deactivated as follows:
The boiler being off (stand-by,) press contemporarily for
five seconds the buttons SUMMER/WINTER and “+” of
heating. The message “of” will appear on the display. The
function can be activated again by pressing the same two
buttons and the appearing message will be “on”.
The diagram aside shows an example of climatic regulation
with Tm1=55°C and Tm2=75°C. When the external
temperature is comprised between 0 and 15° C, the
temperature of delivery stays between 55 and 75°C.
TO ENABLE THE “CHIMNEY SWEEP” FUNCTION – FOR
TECHNICIANS ONLY
1 ON / OFF 5 heating function led 9 sanitary function led
2 RESET 6 heating temperature decreasing 10 sanitary temperature decreasing
3 SUMMER / WINTER 7 display 11 monometer
4 heating temperature encreasing 8 sanitary temperature encreasing
This function blocks the burner power modulation on the
max. value so that combustion tests can be carried out. To
enable this function, turn off the boiler, keep the SUMMER/
WINTER button pressed and turn it on again by pressing
the ON/OFF button: the display flashes until it is disabled.
