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 key (2) and set the boiler on Summer ( ) or Winter ( ).
N.B.: the button (2) must be pressed and held for the time requi-
red to switch from the Stand-by ( ), Summer ( ) or Winter (
) function.
Aer each switch the button must in any case be
released to switch to the next function.
• Summer ( ): when in summer position ( ) the domestic hot
water temperature is adjusted with the buttons (3-4).
• Winter ( ): When the winter position is selected ( ) the
system water temperature is adjusted with the buttons (5-6),
whilst the domestic hot water temperature is adjusted using the
buttons (3-4), by pressing (+) to increase and (-) to reduce the
temperature.
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 (15).
• Operation with Comando Amico Remoto
V2
(CAR
V2
) (optional)
If the CAR
V2
is connected, the boiler regulation parameters can
be set via the CAR
V2
control panel and the button remains
active on the boiler control panel, the "+" and "-" buttons for
DHW and central heating as Set Info requested remotely and
the display where the functioning state is shown.
• Solar operating mode ( ). By selecting this function, the
boiler is set to be used with solar panels.
If parameter P00 is set to "solar" mode, the shutdown is related to
the set DHW set. In OFF mode, the burner is switched o at the
maximum value.
e boiler is set to switch-on immediately aer a request for
DHW.
In the case of coupling with a solar storage tank positioned up-
stream from the boiler, by means of the P04 parameter, it is possi-
ble to compensate the distance between the storage tank and the
boiler in order to allow the water to reach the boiler.
Set the time necessary to verify that the water is hot enough.
Together with a solar valve kit, set the parameter P00
in "solar"on mode (correlated).
“Stand-by” Mode
Press the “Stand-by” button until the ( ); symbol appears; from
this moment the boiler remains o. e antifreeze function,
pump anti-block function and three-way.
ATTENTION:
In “Stand-by” mode, the boiler is to be
considered still live.
