Troubleshooting
Problem encountered
Checks to carry out
The screen of the
control unit does not
turn on.
Check that the switch on the left-hand side of the appliance is set to ON
(
button depressed
).
Check that the appliance is connected to the power supply.
The room temperature
is different from
that displayed by the
appliance.
You have to wait at least 6 hours for the temperature to stabilise.
The appliance does
not heat up.
If you have selected a programme, check that you are in a Comfort time slot.
Check that the installation’s circuit breakers are depressed or that the fail-
safe (
if present
) has not stopped the appliance from functioning. Check the air
temperature in the room: if it is too high, the appliance will not heat up.
The appliance heats
all the time
Check that the appliance is not in a draught (
open door nearby, air outlet via the
cable cover at the rear of the appliance
) or that the temperature setting has not
been altered.
There may be a problem in the electrical network. In the event of a problem
(
thermostat blocked, etc.
), cut the power to the appliance (
fuse, circuit-breaker
) for
about 10 minutes, then switch it on again.
If the phenomenon occurs frequently, ask you energy provider to check the
power supply.
The appliance does
not heat enough.
Increase the temperature by pressing
. If the setting is at the maximum,
perform the following checks:
- Check if another heating method is present in the room.
- Check that your appliance only heats the room in question (
door closed
).
- Have the supply voltage for the appliance checked.
- Check that the power of your appliance is appropriate for the size of the
room (
we recommend an average of 100 W/m
2
for a ceiling height of 2.50 m or
40 W/m
3
).
The surface of the
appliance is very hot.
It is normal that the appliance is hot when operating and the maximum surface
temperature is limited in accordance with the NF Electricity standard. If you
nevertheless feel that your appliance is still too hot, check that the power is
adapted to the 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 appliance is not placed in a draught which affects
its setting.
Traces of dirt appear
on the wall around the
appliance.
In a polluted atmosphere, dirt may appear around the appliance’s air outlets or
on the wall. This phenomenon is linked to the poor ambient air quality (
cigarette
smoke, candles, incense, fireplace, etc.
). In this case, you are advised to check that
the room is suitably ventilated (
ventilation, air intake, etc.
).
