Anomaly signalled Cause Boiler status / Solution
59
Main supply voltage
frequency block
The board detects a main supply voltage frequency anoma-
ly
The boiler does not start (1)
60
Anomaly pump
blocked
The pump is stopped due to one of the following causes:
Impeller blocked, electrical fault.
Try to unblock the pump as described
in the relative section. If normal
conditions are restored the boiler
restarts without having to be reset (1)
61 Air in circulator Air is detected inside the pump; the pump cannot work.
Vent the pump and the central heating
circuit. If normal conditions are
restored the boiler restarts without
having to be reset (1)
62
Complete calibration
required
Missing calibration is detected by the P.C.B. It may occur in
the event the P.C.B. is replaced or if the parameters are al-
tered in the air / gas section, thus requiring “complete cali-
bration”.
The boiler does not start (1)
70
Return/flow probe
exchange
In case of an incorrect boiler wiring connection the error is
detected.
The boiler does not start (1)
72
Fast calibration
required
The P.C.B. detects that some parameters have been altered,
thus requiring “fast calibration”.
The boiler does not start (1)
76
Flow and/or return
probes temperature
drift
A malfunction of one or both system return and flow
probes is detected.
The boiler does not start (1)
77
Combustion control
fault
Out of range current is detected on the gas valve. The boiler does not start (1)
78
Combustion control
fault
High current on the gas valve is detected. The boiler does not start (1)
79
Combustion control
fault
Reduced current on the gas valve is detected. The boiler does not start (1)
80
Block - gas valve
driver issue
This occurs in the event of malfunctions of the P.C.B. that
controls the valve.
Faulty valve
Press the Reset button (1)
84
Combustion anomaly
- power reduction in
progress
A low supply pressure is detected on the gas line. As a result
the appliance power is limited and the anomaly is reported.
If normal conditions are restored the
boiler restarts without having to be
reset (1) (2)
87
Block - gas valve
control
A malfunction of one of the components that controls the
gas valve has been detected.
The boiler does not start (1)
88
Block - gas valve
control
A malfunction of one of the components that controls the
gas valve has been detected.
The boiler does not start (1)
89
Combustion signal
unstable
The flame is unstable due to: presence of flue gas recircula-
tion, wind, unstable gas pressure, unstable fan speed, or
due to system malfunction.
The boiler keeps working (1) (2)
90
Combustion signal
beyond limit
The combustion signal is beyond the adjustment range re-
quired for an extended period of time.
The boiler keeps working (1) (2)
91
Incorrect ignition
block
The board has exhausted all possible actions in order to ob-
tain optimal ignition of the burner.
Press the Reset button (1)
92
Fan revs correction
limit
The system has exhausted all possible corrections of the
number of fan revs.
The boiler keeps working (1) (2)
(1) If the shutdown or fault persists, contact an authorised company (e.g. Authorised Service Centre)
(2) The anomaly can only be verified in the list of errors in the “Information” menu
