2.4 Ignition of the boiler.
Before ignition make sure the heating system is lled with water
and that the manometer (7) indicates a pressure of 1 ÷ 1.2 bar.
- Open the gas cock upstream from the boiler.
- Press the button (2) until the display switches on, aer which
press the button in sequence (2) and take the boiler to the sum-
mer ( ) or winter ( ) position.
• Summer ( ): in this mode the boiler functions only to heat
the DHW, the temperature is set via the buttons (3-4) and the
relative temperature is shown on the display via the indicator
(16).
• Winter ( ): in this mode the boiler functions both for heating
domestic hot water and heating the environment. e temper-
ature of the DHW is always regulated via buttons (3-4), the
heating temperature is regulated via buttons (5-6) and the relative
temperature is shown on the display via the indicator (16).
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 boiler ignites, the relative ame present symbol is displayed
(10) with relative power scale.
• Operation with Comando Amico Remoto
V2
remote control
(CAR
V2
) (Optional). If the CAR
V2
is connected, the ( )
symbol will appear on the display. e boiler regulation param-
eters can be set via the CAR
V2
control panel and the reset button
(1) remains active on the boiler control panel, along with the
switch-o button (2) (“o” mode only) and the display where
the functioning state is shown.
ATTENTION:
if the boiler is put into “o” mode on
the CAR
V2
the “CON” connection error
symbol will appear on the CAR
V2
. e CAR
V2
is
however powered constantly so as not to loose
memorised programs.
• Functioning with optional external probe ( ). In the case of
a system with optional external probe, the boiler ow tempera-
ture for room central heating is managed by the external probe
depending on the external temperature measured (Par. 1.10). e
ow temperature can be modied by selecting the functioning
curve via buttons (5 and 6), selecting a value from “0 to 9” (Fig.
33).
With external probe present, the relative symbol will appear on
the display (11). In the central heating phase, if the temperature
of the water contained in the plant is sucient to heat the ra-
diators, the boiler can only function with the activation of the
boiler pump.
• “Stand-by” mode. Press button (2) in succession until the ( )
symbol appears. e boiler remains active from this moment and
the anti-freeze function, pump anti-block function and 3-way
and signalling of any anomalies is guaranteed.
ATTENTION:
in “Stand-by” and “Off” mode, the
boiler is still powered.
• “O” mode. By holding the button (2) down for 8 seconds, the
display switches-o and the boiler is o completely. e safety
functions are not guaranteed in this mode.
ATTENTION:
in “Stand-by” and “Off” mode, the
boiler is still powered.
• Display functioning. e display lights up during the use of the
control panel, aer 15 seconds inactivity, the brightness drops
until just the active symbols are displayed. e lighting mode can
be varied via parameter P2 in the circuit board customisation
menu.
