DIAGNOSTIC
14.2. - The 'error' codes
'Error' codes are a precious aid to diagnostic. Take care to well identify the model to be troubleshooted,
as codes do not always have the same meaning.

NTC T°C < 5°C Room too cold Sans objet
Front source: Pb of
shorted NTC (F1) or open
circuit (F2)
Front source: Pb of shorted NTC
(F1) or open circuit (F2)
Rear source: Pb of
shorted NTC (F3) or open
circuit (F4)
Check the assembly,
connection and ohmic value
of the NTC.
Rear source: Pb of shorted NTC
(F3) or open circuit (F4)
Check the assembly,
connection and ohmic
value of the NTC.
Check of transistors: Pb
of shorted NTC (F5) or
open circuit (F6)
Replace the board, as NTC
and transistors are
interdependent

T°C of transistors > 70°C
and of
electronics > 105°C
Check the installation
Check the ventilation.
T°C of electronics > 70°C. The
message is followed by a crawler
until the problem is solved.
Check the installation
Check the ventilation.
Reversal of front and rear
NTC's
Check the crimping of
NTC's on their comb, and
the right assembly. If they
are correct: Replace the
board.

If the user acts on a non-covered
key, the display is resumed after
1 min with a ‘beep’ every 8s and
then stops.
