does not turn on.
Check that the switch located behind or on the side of the appliance is
in the I position. Check that the appliance is correctly powered.
The radiator does not
heat up.
If you have accessed programming, check that the programming is set
to COMFORT.
Check that the installation's circuit-breakers are triggered or even that
the cut-off device (if present) has not cut-off heating.
Check the air temperature in the room: if it is higher than the setpoint
temperature, then it is normal for the appliance not to heat up.
The radiator heats up
continuously.
Check that the appliance is not located in an air current or that the
setpoint temperature adjustment has not been increased.
The radiator does not
heat up sufficiently.
Increase the Comfort setpoint temperature.
If the adjustment is at the maximum, perform the following checks:
- Check whether there is another form of heating in the room;
- Ensure that your appliance only heats up the room (door closed);
- Check the power supply voltage for the appliance;
- Check whether the power of your appliance is suitable for the size of
your room (we recommend an average of 100 W/m
2
for a ceiling
height of 2.50 m or 40 W/m
3
).
Traces of dirt appear on
the wall around the
appliance.
The dirt is associated with poor ambient air quality. In this case, we
recommend checking that the room is properly ventilated (ventilation,
air inlet, etc.) and checking the cleanliness of the air and avoiding
smoking inside. This dirt does not constitute grounds for warranty
replacement of the appliance.

when the radiator is in
ECO mode.
This operation is normal. The radiator can heat up to maintain an Eco

MODE and that external control is selected.
The surface of the
radiator is very hot.
It is normal for the appliance to be hot when it operates, the maximum
surface temperature is limited in accordance with the NF Electricity
Performance standard. However, if you feel that your appliance is
always too hot, check that the power is suitable for the surface area of
your room (we recommend 100 W/m
2
for a ceiling height of 2.50 m or
40 W/m
3
) and that the appliance is not placed in an air current that
could interfere with its adjustment.
A "paired" appliance
does not communicate
with the other "paired"
appliances.
Check that the appliance is correctly paired (refer to the
"CONNECTIVITIES" chapter). Delete the entire pairing procedure and
restart the procedure.
A maximum of 5 appliances can be paired. The maximum range is from
100 to 300 metres in free-field conditions / for 20 m2 concrete slabs.
