(1) If the block or anomaly persists, contact an authorised company (e.g. Immergas Technical After-Sales Service).
(2) If normal operating conditions are restored, the boiler re-starts without having to be reset.

FE94 Display board anomaly An error is detected on the display's P.C.B..

FE97 Configuration error
(1) If the block or anomaly persists, contact an authorised company (e.g. Immergas Technical After-Sales Service).
(2) If normal operating conditions are restored, the boiler re-starts without having to be reset.
Cause
This occurs during the power-on phase in the event of a leak on the
detection circuit or anomaly in the flame control unit.
Number of allowed resets that have already performed.
An error is detected on the P.C.B. and the boiler does not start up
The board detects a short circuit on the DHW NTC probe
The board detects an open contact on the DHW NTC probe.
This occurs when the power supply voltage is lower than the allowed
limits for the correct boiler operation.
If the system pressure is too low the boiler switches off.
The board detects a short circuit on the flue NTC probe.
The board detects an open contact on the flue NTC probe.
With the boiler in stand-by, the board detects an anomalous difference
between the NTC probe flow and return temperatures. The error may
be caused by a failure in one of the two probes
Occurs if the communication between the display boards breaks down
A communication error has been detected between the display board
and the boiler's P.C.B.. In the event of simple cascade, even in the case
of a communication error between the display boards.
Cause
The board detects an incorrect value on the flow NTC probe or "P38"
parameter not set correctly..
An anomaly is detected on the external probe.
P.C.B. configuration error.
This may happen when the P.C.B. is changed It may occur also in the
event of replacement of the electronic boards with an incorrect model..

Attention: it is possible to reset the anom-
aly up to 5 consecutive times within 15
minutes. (1) By switching the appliance
on and off 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.
