(1) If the block or anomaly persists, contact an authorised company (e.g. Authorised Technical After-Sales Service).
Cause
In the event of request of room central heating or domestic hot
water production, the boiler does not switch on within the preset
time. Upon appliance commissioning or after extended down-
time, it may be necessary to eliminate the block.
During normal operation, if a fault causes excessive overheating
internally, the boiler goes into overheating block.
This occurs if the fan is blocked or if the intake or drain pipes
are obstructed.
This takes place if the boiler board microprocessor erroneously
recognises a signal.
The board detects an anomaly on the flow probe.
Number of allowed resets that have already performed.
Water pressure inside the central heating circuit that is sufficient
to guarantee the correct operation of the boiler is not detected.
This occurs in case of a fault in the flue pressure switch or the fan.
If the board detects an anomaly a the storage tank probe, the
boiler cannot produce domestic hot water.
If the board detects an anomaly or incongruity on the electric
wiring, the boiler will not start.
This occurs in the event of a leak on the detection circuit or
anomaly in the flame control unit.
The board detects an anomaly on the pushbutton panel.
This occurs if there is overheating in the boiler due to insufficient
water circulating in the primary circuit; the causes can be:
- low system circulation; check that no shut-off devices are closed
on the heating circuit and that the system is free of air (deaer-
ated);
- pump blocked; free the pump.
This occurs 1 minute after communication loss between the boiler
and the remote control.
Boiler status / Solution
Press the Reset button (1).
Press the Reset button (1).
If normal conditions are restored the boiler
restarts without having to be reset (1).
Press the Reset button (1).
The boiler does not start (1).
Attention: the anomaly can be reset 5 times
consecutively, after which the function in
inhibited for at least one hour. One attempt
is gained every hour for a maximum of 5 at-
tempts. By switching the appliance on and off
again, the 5 attempts are re-acquired.
Check on the boiler pressure gauge (1) that
the system pressure is between 1÷1.2 bar and
restore the correct pressure if necessary.
If normal conditions are restored the boiler
restarts without having to be reset (1).
(1).
If normal conditions are restored the boiler
restarts without having to be reset. Check that
the boiler is configured correctly (1).
Press the Reset button (1).
If normal conditions are restored the boiler
restarts without having to be reset (1).
If normal conditions are restored the boiler
restarts without having to be reset (1).
Switch the boiler on and off again (1).
