PROBES EXCHANGED
 The C.P.U. detects that the start-up electrode
of tension output of the C.P.U. corresponding
to the electrode are in short-circuit.
 Gas outlet temperature is not sufficient for
correct functioning; the minimum must be
o
100 C.
 The gas outlet sensor does not detect the
temperature required for operation.
 The C.P.U. does not detect items of
~230/240V - 50Hz. If the stove is new, this
might be caused by electrical problems. If it
happens after repair, it might be due to the
non connection of the motors terminal strips.
 Failure or possible failure in the C.P.U.
 Gas outlet probe is exchanged by the NTC.
 If the stove is new, this might be caused by
electrical problems.
 Check with a multimeter if the motor is
clamped to earth or the winding is in short-
circuits.
 Make sure power reaches the convection
motor, see menu 3 section 3.
 Check the black cable going out from the
C.P.U. Connect it if necessary.
 This is the first start-up of the stove, wait until
the Motors stop and turn i ton again.
 There were no pellets in the stove. Fill the
hopper in.
 The screw of the endless motor is obstructed.
Unblock it.
 Check the quality of the pellets, see if it
contains much sawdust or humidity. Buy a
new bag of pellets.
 The stove is dirty and stopped the pellets drop
for security reasons. Carry out maintenance.
 The safety thermostat is armed.
 Gas outlet sensor damaged. Replace it.
 C.P.U. damaged. Replace it.
 Disconnect the Test of Control of the
hardware in menu 1-7b, disconnect the stove
and connect it again; if everything works well,
tension decreases or you hear noise in the
electric mains.
 Check with a multimeter that the motors are
not in short-circuits.
 Disconnect the Test of Control of the
hardware in menu 1-7b, disconnect the stove
and connect it again; if everything works well,
tension decreases or you hear noise in the
electric mains.
 The thermocouple and NTC are exchanged,
see wiring diagram.
