Troubleshooting
Problem encountered
Checks to carry out
The control panel
does not light up.
The display is on standby. Press any button to activate the display. Check
that the appliance is connected to the power supply. Check that the
switch is in position I.
The heating indicator
does not light up.
The heating indicator lights up when the power supply to the resistor
is on.
Check the ambient temperature. If it is above the setpoint temperature,
it is normal for the indicator not to light up
Check that the indicator lighting is active. Look up “Heating standby
indicator”
The room
temperature is
different from that
displayed by the
appliance.
You have to wait at least 6 hours for the temperature to stabilise.
Depending on your installation, you may read a different temperature to
that displayed on the appliance. You can adjust the setpoint temperature
to the temperature read in the room (see «Calibration»).
The appliance does
not heat up.
If you have selected a programme, check that you are in a Comfort time
slot. Make sure that the installation's circuit breakers are engaged. Check
the air temperature in the room: if it is too high compared to the setpoint
temperature, the appliance will not heat up.
The appliance heats
all the time
Check that the appliance is not in an air current (
open door nearby, cold air
intake via the connection box at the rear of the appliance, ventilation system
)
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 jammed, etc.
), cut the power to the appliance (
fuse,
circuit breaker
) for about 10 minutes, then switch it on again
The appliance does
not heat enough.
Increase the setpoint (see “Manual mode”).
If the setting is at its maximum, make 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
).
- 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 appliance takes
time to heat up.
The electric heater heats up the fluid, which gradually and naturally starts
circulating inside the appliance. The fluid's inertia properties mean that
the appliance's surface temperature only reaches an optimal level after at
least 15 mins, depending on the ambient temperature and losses from the
room when the appliance is heating up.
The surface of the
appliance is very hot.
The appliance can be expected to be hot when operating, while the
maximum surface temperature is limited in accordance with the NF
standard "Électricité Performance" [electrical performance]. If however
you feel that your appliance is still too hot, check that the power is suited
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 the appliance is not placed in an air
current affecting its regulation (e.g.: under a ventilation system). Check
the room temperature against the setpoint temperature.
The top and bottom
parts are less hot
than the rest of the
appliance
At the top, the upper parts are not completely filled to enable
thermodynamic fluid expansion. They are heated by conduction.
At the bottom, the lower parts carry back the fluid which has transmitted
its heat.
