The large digits will light up on the display, indicating the selected
temperature value.
A
- Press the key and turn the encoder to select the required tem-
perature (only with storage tank connected). The large digits will
light up on the display, indicating the selected temperature value.
After a few seconds, the display will again show the outlet temper-
ature actually measured by the boiler probe.

A
- Press the key to select the type of operation. Depending on
the type of operation chosen, the display will visualise just the do-
mestic water comet (heating function deactivated) or both comets
(heating function activated). The following conditions may occur:
- If there is no heat request, the boiler will go into standby,
- if there is a heat request, the boiler will start up and one of the
flames will light up according to the type of request.
The boiler will continue operating until the set temperatures are
reached, after which it will go into standby.
If there are any firing or operation faults, the boiler will make a “safety
stop”; the display will show a flashing code and the RESET and
icons will appear (simultaneously or otherwise).
For the description of the fault and to reset the starting conditions see
the section “Display and fault codes” and the relevant table.
After a “safety stop”, wait about 10 seconds before restoring
the start-up conditions.
D - Adjusting the heating temperature
To adjust the temperature of the outlet water, press the heating tem-
perature adjustment key
.
A
The two digits will no longer show the temperature measured instan-
taneously by the probe, but the temperature (flashing) previously set.
By rotating the encoder A, you can raise or lower the temperature.
When 3 seconds have passed since the last modification, the value is
automatically stored and the display again shows the value measured
instantaneously by the probe.
The set temperature is displayed both numerically (e.g.. 55° C) and as
illumination of the comet.
During the heating adjustment, when passing from the minimum value
to the maximum value you will meet the sector of the C.T.R. system:
Heating Temperature Control (from 55°C to 65°C).
The C.T.R. system independently manages the outlet temperature
adapting the operation to the actual needs of the home.
When the heat requirement continues for some time, the outlet tem-
perature increases in order to heat the room more quickly.
Once the required comfort level has been reached, the system brings
the outlet temperature back to the value set at the beginning.
This ensures lower consumption, less scale formation in the boiler, and
reduced temperature swings in the radiators.
E - Adjusting the heating temperature with
an external probe connected
If there is an external probe, the outlet temperature value is automati-
cally chosen by the system, which quickly adapts the ambient temper-
ature to any variations in the outdoor temperature.
The display shows the external probe icon, and only a central seg-
ment is lit up in the heating comet.
