The display will show the temperature in the
boiler or the domestic hot water temperature
depending on the request in progress.
The boiler will continue operating until the
set temperatures are reached, after which it
will go into standby, in any event maintain-
ing the temperature displayed.
If there are any firing or operation faults, the
boiler will make a “safety stop”; on the con
-
trol panel the green led (1) will go out, the
display will show a blinking fault code and,
in the event of a lockout also the red led (3)
will come on.

Depending on the type of system, the
most suitable temperature range can be
pre-selected:
− standard systems 40-80 °C
− floor installations 20-45°C.

Adjusting the heating water
temperature with an external
probe connected
If there is an external probe, the outlet tem-
perature value is automatically chosen by the
system, which quickly adapts the ambient
temperature to any variations in the outdoor
temperature.
If you want to alter the temperature value
(increasing or reducing the value automat-
ically calculated by the electronic card), use
the heating water temperature selector (4):
turn it clockwise to increase the temperature,
or anticlockwise to reduce it.
