Description of functioning states

Summer functioning mode without request in progress.
SUMMER
Boiler in stand-by for domestic hot water request.
HU
Winter functioning mode without request in progress.
WINTER
Boiler in stand-by for domestic hot water or central heating request.
Domestic hot water mode in progress.
DHW ON
Boiler functioning, domestic hot water heating in progress.
RO
Central heating mode in progress.
CH ON
Boiler functioning, central heating in progress.
Anti-freeze mode in progress.
IE
F3 Boiler functioning to restore the minimum safety temperature against boiler
freezing.
CAR OFF Remote Control (Optional) off.
SK
In the case of use with Super CAR in concomitance with the functioning
DHW OFF
period in reduced D.H.W. Timer mode, DHW OFF will appear on the display
and indicators 15 and 2 switch off (see Super CAR instructions manual).
Postventilation in progress.
F4
Fan in function after a request for domestic hot water or central heating in order
to evacuate residual fumes.
Postcirculation in progress.
F5
Pump in function after a request for domestic hot water or central heating in
order to cool the primary circuit.
With Remote Control (Optional) or environment thermostat (TA) (Optional) in
block, the boiler functions all the same in central heating mode. (Can be activa-
P33
ted through the "Customisation" menu. It allows to activate the central heating
even if the Remote Control or TA are out of order).
Reset attempts finished
STOP
Wait for 1 hour to re-acquire 1 attempt.
(See Ignition block).
Anomaly present with relative error code.
ERR xx
The boiler does not work. (see troubleshooting paragraph).
During the rotation of the domestic hot water temperature selector switch (1 Fig.

2-1) view the state of the adjustment of the domestic hot water temperature in
progress.
During rotation of the central heating selector switch (3 Fig. 2-1) the adjustment
SET
status of the boiler flow temperature for central heating is displayed.
In presence of the external probe (optional) replace the "SET CH" item.
The value that appears is the correction of the flow temperature with respect to
SET
the functioning curve set by the external probe. See OFFSET on external probe
graphics (Fig. 1-7).
System deaeration in progress.
F8
During this phase, which lasts 18 hours, the boiler pump is started at pre-establi-
shed intervals, thus allowing deaeration of the heating system.
Only in the case of use with Super CAR, does it allow to activate the anti-legio-
F9
nella function, which takes the temperature of the water in the storage tank to
65°C for 15 minutes. (see Super CAR instruction manual).
Solar function.
The solar function is activated to control just the pump for DHW.
SOLAR
When the solar pump is powered, the display will show 'SOLAR' , which may
alternate with other function texts in progress.
SOLAR ON
The solar pump functions permanently.
SOLAR OFF The solar pump stays off.

2.5 USING THE BOILER.

Before ignition make sure the heating system is
filled with water and that the manometer (23)
indicates a pressure of 1 - 1.2 bar; Open the gas
cock upstream from the boiler. With the boiler
off, only the stand-by symbol (10) appears on the
display. By pressing the (

switches on. Once the boiler is on, by pressing
ans of the indicator (6) with a brief description.
Refer to the instruction book for a complete
explanation.
button "A" repeatedly, the functioning mode

circuit is completely automatic and does not
) button the boiler
require regulation by the user. The function is
always active with the boiler on and must be
kept so in the summer and in the winter. In
the case of faults on the boiler, the solar circuit
continues to function supplying heat to the
water according to the possibility of the system
and the weather conditions. Putting the boiler
in stand-by (
preventing disposal of the heat accumulated. It
is therefore important to have the solar collec-
tor correctly covered by qualified staff.
• Summer (
tions only to heat domestic hot water. The
temperature is set using the selector switch
(1) and the relative temperature is shown on
the display (24) by means of the indicator (2)
and the "SET" indication appears (Fig. 2-2). By
turning the selector switch (1) in a clockwise
direction the temperature increases and in an
anti-clockwise direction it decreases.
During the heating of the domestic hot water
"DHW ON" appears on the display (24) on
the status indicator (6) and at the same time
as burner ignition the flame presence indicator
switches on (8) with relative power scale and
the indicator (9 and 7) with the instantane-
ous outlet temperature from the primary heat
exchanger.

• Winter ( ): in this mode the boiler functions
both for heating domestic hot water and heat-
ing the environment. The temperature of the
domestic hot water is always adjusted using the
selector switch (1), the heating temperature is
adjusted using the selector switch (3) and the
relative temperature is shown on the display
(24) using the indicator (4) and the "SET"
indication appears (Fig. 2-4). By turning the
selector switch (3) in a clockwise direction the
temperature increases and in an anti-clockwise
direction it decreases.
