F - Operation in heating mode
The symbol flashes when the boiler
receives a request in heating mode
(*). If a request for domestic hot
water production is received at the
same time, the symbol stays fixed
on and the symbol
flashes
G - Operation in hot water
production mode
This symbol lights up when there is
a request for domestic hot water (*).
(*)
all the functions requested must be acti
-
vated via
B/C
I - Block signal
The symbol lights up when the
burner safety device has inter-
vened, due to:
- No gas
- Failed ignition
In the first case, in which the burner
will not light, one must check if the
gas valve is open.
M - Fault signal
The symbol lights up on the display
monitor when the boiler detects an
operation anomaly or it is blocked
due to a permanent fault. The
code that identifies the cause is
displayed in place of the degrees
centigrade:
fixed (by pressing the reset button
D
) if it belongs to unit 1
(the burner attempts ignition)
flashing if it belongs to unit 2
(ignition is inhibited).
6.2 - CHECKS BEFORE COMMISSIONING
1 Make sure the gas shut-off valve upstream of
the boiler is open.
2
Check that any shut-off valves
for maintenance, on the flow and
return are open.
3
Check that the shut-off valve, for maintenance,
on the domestic cold water inlet is open.
4 Check that the safety valves outlet /condensa
-
tion drain has been connected to the drains.
5
Check that the boiler is powered electrically;
the display
(E)
on the control panel must be
lit up.
6 Check the water pressure on the boiler pres
-
sure gauge
(A)
; for optimum operation, the
pressure should be between 0.8 and 1 bar
(with pump stopped).
Should the pressure be lower than 0.7 bar with
the system cold, restore pressure by opening
the system filling tap (see par. 6.4).
D - Unblock button
By acting on this button one can:
- restart the boiler after the burner
safety device has intervened, ac
-
tivating the symbol on the display
- display the error code when the
boiler operation is block due to
a permanent fault, activating the
symbol on the display.
Thermometer
If, on the display, the symbol
(
) is lit up, the temperature
indicated is that relating to the water
for the heating circuit
If, on the display, the symbol
(
) is lit up, the temperature
indicated is that relating to the water
for the domestic hot water circuit.
A - Pressure gauge
Displays the water pressure inside
the heating circuit; this pressure
value must not be below 0.8/1 bar
(when cold).
If the pressure drops below 0.8/1
bar, one must restore the correct
value by acting on the system fill
-
ing valve. This operation must be
carried out when the boiler is cold.
