2.4 USING THE BOILER.
Before ignition make sure the heating system
is filled 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 (6) until the display switches
on. The boiler now returns to the state prior to
switch-off.
- If the boiler is in stand-by, press the button (6)
again to activate it. If this is not the case, go to
the next point.
- Then press the button (3) in sequence and set
the boiler in the summer ( ) or winter ( )
position.
•
Summer
( )
:
in this mode the boiler only
works to produce DHW; the temperature is set
via the selector (1) and the relative temperature
is shown on the display via the indicator (14).
• Winter ( ) : in this mode the boiler works
both for producing domestic hot water and for
central heating. The temperature of the DHW is
always regulated via the selector (1), the heating
temperature is regulated via selector (4) and the
relative temperature is shown on the display via
the indicator (14).
From this moment the boiler functions automati-
cally. 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 flame.
Each time the burner ignites, the relative flame
present symbol is displayed (10) with relative
output scale.
•
Operation with Comando Amico Remoto
V2
(CAR
V2
) (Optional) . If the CAR
V2
is connected,
the ( ) symbol will appear on the display.
The boiler regulation parameters can be set via
the CAR
V2
control panel and the reset button
(2) remains active on the boiler control panel,
along with the switch-off button (6) (“off ”
mode only) and the display where the function-
ing state is shown.
Caution:
if the boiler is switched “off” the
CAR
V2
will display the connection error symbol
“ERR > CM”, the CAR
V2
is however powered
constantly so as not to lose the stored programs.
•
Boost Function.
Pressing the “Info” and
“Reset” buttons at the same time activates
the “Boost” function indicated by the relative
icon on the display. When the boiler is active
it is maintained at a sufficient temperature to
ensure the instantaneous delivery of hot water.
To maintain the temperature the boiler may be
switched on even without requests for domestic
hot water or central heating; this type of op-
eration is indicated by the “BOOST” message
flashing.
•
Solar operating mode ( ).
This function
is always active and combined with the “Solar
ignition delay” with time set above 0 seconds
it manages the ignition of the boiler according
to the domestic hot water inlet temperature.
During a withdrawal, if the inlet water is hot
enough or if there is “Solar ignition delay” time,
the boiler does not switch on, the D.H.W. with-
drawal symbol (
) appears on the display
along with the flashing solar function symbol
(
).
When the water supplied by the solar system is
at a temperature lower than what is set, and / or
if the “Solar ignition delay” time has elapsed,
the boiler switches on. At this point, the solar
function symbol will go off.
• Operation with optional external probe
( ) . In the case of a system with optional
external probe, the boiler flow temperature
for room central heating is managed by the
external probe depending on the external
temperature measured (Par. 1.9). The flow
temperature can be modified by selecting the
functioning curve via the selector switch (4)
(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 (18) will appear on the display. In the
central heating phase, if the temperature of the
water contained in the system is sufficient to
heat the radiators, the boiler can only function
with the activation of the pump.
• “Stand-by” mode. Press button (6) repeatedly
until the symbol ( ) appears. From now on
the boiler remains inactive and the anti-freeze
function, pump anti-block function and 3-way
and signalling of any anomalies is guaranteed.
N.B.: in these conditions the boiler is still
powered.
•
“Off” mode.
By holding the button (6) down
for 8 seconds, only the central point remains lit
on the display, and the boiler is off completely.
The safety functions are not guaranteed in this
mode.
N.B.:
in these conditions the boiler is consid-
ered still live even if there are no functions
active.
• “Automatic vent” mode. When the function
is enabled, every time the boiler is electrically
powered, the system automatic vent function
is activated (lasting 8 minutes). This function
is displayed via a countdown signalled by the
indicator (14). During this period the DHW
and CH functions are not active.
The “automatic vent” can be annulled by press-
ing the “reset” button (2).
• Display operation. The display lights up while
the control panel is being used; after a set in-
activity period, the brightness drops until only
the active symbols are displayed. The lighting
mode can be varied via parameter t8 in the
P.C.B. programming menu.
