Error
Anomaly signalled Cause Boiler status / Solution
08
Maximum N° of
resets
Number of allowed resets that have already been performed.
Attention: the anomaly can be reset up to 5
consecutive times, after which the function
is inhibited for at least an hour and one at-
tempt is gained every hour for a maximum
of 5 attempts. By switching the appliance
on and off, the 5 attempts are re-acquired.
10
Insufficient system
pressure
Insufficient water pressure inside the central heating circuit is detected,
which guarantees correct boiler operation.
Verify that the system ranges between 1÷1.2
bar on the manometer and if necessary
restore the correct pressure.
12
Storage tank probe
anomaly
The board detects an anomaly on the storage tank probe.
The boiler cannot produce domestic hot
water (1).
15 Configuration error
If the board detects an anomaly or incongruity on the electric wiring, the
boiler will not start.
If the normal operating conditions are
restored, the boiler restarts without having
to be reset. (1)
20
Parasite flame
This occurs in the event of a leak in the detection circuit or an anomaly
in the flame control unit.
Press the Reset button (1)
24
Push button control
panel anomaly
The board detects an anomaly on the pushbutton panel.
If the normal operating conditions are
restored, the boiler restarts without hav-
ing to be reset (1)
27
Insufficient circula-
tion
This occurs if there is overheating in the boiler due to insufficient water
circulating in the primary circuit; the causes may be:
- poor system circulation; check that there is no interception on the closed
heating circuit and that the system is perfectly free of air (deaerated);
- blocked pump; free the pump.
Press the Reset button (1).
31
Loss of remote
control communi-
cation
This occurs if communication is lost between the boiler and the CAR
V2
. Disconnect and reconnect the power to
the boiler (1).
37
Low power supply
voltage
This occurs when the power supply voltage is lower than the allowed
limits for the correct boiler operation.
If the normal operating conditions are
restored, the boiler restarts without having
to be reset (1).
(1) If the shutdown or fault persists, contact an authorised firm (e.g. Authorised Technical After-Sales Service).
