2.4 USING THE BOILER.

Before ignition make sure the heating system
is lled with water and that the manometer (8)
indicates a pressure of 1 ÷ 1.2 bar.

tions only to produce the DHW, the temper-

relative temperature is shown on the display
via the indicator (19). Moreover, the tempera-
ture level that can be selected is shown on the
indicator (22).
• Winter (
): in this mode the boiler works
both for producing domestic hot water and
for central heating. e DHW temperature is
always regulated via the buttons "
central heating temperature is regulated via the
buttons " " and the relative temperature
is shown on the display via the indicator (19).
Moreover, the temperature level that can be
selected is shown on the indicator (15).
From this moment the boiler functions automat-
ically. With no demand for heat (central heating
or domestic hot water production) the boiler
goes to "standby" function, equivalent to the
boiler being powered without presence of ame.
Each time the burner ignites, the relative ame
present symbol is displayed (11) with relative
output scale.
