2.5 USING THE BOILER.
Before ignition, make sure that the system is
full of water, checking that the manometer (5)
indicates a base value at which the system has
been designed and calculated and however not
less than 0.5 bar.
- Open the gas cock upstream from the boiler.
- Turn the main switch, and the boiler runs a
self-diagnosis. It will then go back to the status
it was in prior to being switched off.
• “A” operating mode button(
):
with
the boiler on, press the button (A) repeatedly
to change the operating mode. It will alternate
from summer mode (
) ) (DHW heating
only) to winter mode (room and DHW heat-
ing).
N.B.:
the DHW heating function is only active
in presence of the specific optional kit (tank
probe automatic recognition).
With the boiler on but not running, the screen
will display the flow probe temperature reading.

If requested, the boiler switches on and the rel-
ative symbols will be displayed, indicating the
flow probe temperature reading.
Warning

not saved in the anomaly records.

. Slave boiler anomalies are dis-
played on the Master boiler. After entering the
menu, press + and - (ref. 8 fig. 2-1) to alternate
between Master “bu 0” and Slave “bu 1” boilers.
