Cause
If room central heating or domestic hot water production is
requested, (when the boiler is paired with a storage tank
unit) 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 over-
heating internally, the boiler goes into overheating block.
During normal operation, if a fault causes excessive flue gas
overheating, the boiler blocks.
The P.C.B. detects a fault on the gas valve supply. Check its
connection. (the anomaly is detected and displayed only in
the event of a request). Once it has been established that the
fault is not related to the gas valve, the P.C.B. must be re-
placed if the fault does not disappear after pressing the Re-
set button.
The board detects an anomaly on the flow NTC probe.
Water pressure inside the central heating circuit that is suf-
ficient to guarantee the correct operation of the boiler is not
detected.
The board detects a fault on the storage tank probe (when
paired with a storage tank unit).
If the board detects an anomaly or incongruity on the elec-
tric wiring, the boiler will not start.
This occurs if the fan has a mechanical or electrical fault.
Boiler status / Solution
Press the Reset button (1).
Press the Reset button (1).
Press the Reset button (1).
Press the Reset button (1).
The boiler does not start (1).
The anomaly can be reset 5 times
consecutively, after which the
function is inhibited for at least one
hour. One attempt is gained every
hour for a maximum of 5 attempts. By
switching the appliance on and off
again, the 5 attempts are re-acquired.
Check on the boiler pressure gauge
that the system pressure is between
1÷1.2 bar and restore the correct
pressure if necessary.
The boiler cannot produce domestic
hot water (1).
If normal conditions are restored the
boiler restarts without having to be
reset. Check that the boiler is config-
ured correctly (1).
Press the Reset button (1).
