Anomaly signalled Cause Appliance status / Solution
91
Incorrect ignition
block
e 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
e system has exhausted all possible corrections of the
number of fan revs.
e appliance keeps working (1) (2)
93
Combustion signal
beyond limit
e combustion signal is beyond the adjustment range re-
quired for a limited period of time.
e appliance keeps working (1) (2)
94 Combustion anomaly
A problem is detected on the combustion control, which
may be due to: gas low pressure, ue recirculation, defective
gas valve or P.C.B.
If normal conditions are restored, the
appliance restarts without having to
be reset (1) (2)
95
Combustion signal
discontinuous
e system detects a discontinuous combustion signal. e appliance keeps working (1) (2)
96 Clogged ue
is occurs in the event an obstruction is detected in the
ue system.
e appliance does not start (1). If
normal conditions are restored the
boiler restarts without having to be
reset
If error 96 appears aer the Techni-
cian has made changes on the "ue"
parameters, it is necessary to perform
a "quick calibration".
