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.
- Open the gas cock upstream from the boiler.
- Press the button “ “ repeatedly to cyclically switch from
“stand-by” ( ) to “summer” ( ) and “winter” ( ) mode.
• Summer ( ): in this mode the boiler functions only to produce
the DHW, the temperature is set 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 (22).
• Winter ( ): in this mode the boiler works both for producing
domestic hot water and for central heating. e DHW tem-
perature is always regulated via the buttons “ “, the 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 automatically. With no
demand for heat (central heating or domestic hot water pro-
duction) 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.
• Operation with Comando Amico Remoto
V2
(CAR
V2
) (Option-
al). If the CAR
V2
is connected, the ( ) symbol will appear on
the display. e boiler regulation parameters can be set via the
CAR
V2
control panel and the reset button (3) remains active on
the boiler control panel, along with the switch-o button (1)
(“o” mode only) and the display where the functioning state
is shown.
N.B.: if the boiler is put into “o” mode, the “ERR>CM” con-
nection error symbol will appear on the CAR
V2
. e CAR
V2
is
however powered constantly so as not to lose memorised pro-
grams.
• Solar operating mode ( ). is function is activated automat-
ically id the boiler detects a probe on the DHW inlet (optional)
or if the “Solar ignition delay” parameter is more than 0 seconds.
During a withdrawal, if the outlet water is hot enough or if there
is “Solar ignition delay” time, the boiler does not switch on, the
D.H.W. withdrawal symbol ( ) appears on the display along
with the ashing solar function symbol ( ).
When the water supplied by the solar system is at a temperature
lower than what is set, or if the “Solar ignition delay” time has
elapsed, the boiler switches on. At this point, the solar function
symbol remains permanently on.
• Operation with optional external probe ( ). In the case of a
system with optional external probe, the boiler ow temperature
for central heating is managed by the external probe depending
on the external temperature measured (Par. 1.11). e ow tem-
perature can be modied by selecting the functioning curve via
the buttons “ “ (or on the CAR
V2
control panel, if connected
to the boiler) selecting a value from “0 to 9”.
With external probe present, the relative symbol (12) will appear
on the display. In the central heating mode, if the temperature
of the water contained in the system is sucient to heat the
radiators, the boiler can only function with the activation of the
pump.
• “Stand-by” mode. Press button “ “ repeatedly until the
symbol ( ) appears. e boiler remains o from this moment,
though the antifreeze, pump anti-block and 3-way function and
signalling of any anomalies are guaranteed.
• “O ” mode. By holding the button “ ” down for 8 sec-
onds, the display switches-o and the boiler is o completely.
e safety functions are not guaranteed in this mode.
ATTENTION:
in “Stand-by” and “O” mode, the boil-
er is to be considered still live.
• Display operation. e display lights up while the control panel
is being used; aer a set inactivity period, the brightness drops
until only the active symbols are displayed. e lighting mode can
be varied via parameter “t8” in the P.C.B. programming menu.
