HECKS TO BE MADE
The device does not
heat.
- Check that the cursor is on position .
- If you are operating under programming, check that the programmer is in
COMFORT mode.
- Ensure that the installation’s circuit breakers are engaged and that the power
cut-off (
if you have one
) has not cut off the power to the device.
- Check the air temperature in the room: if it is too high, the heating light
E
does not illuminate: the device does not heat.
- Check that the control knob
B
is not in Airing position and that there
are no draughts.
The device heats all
the time.
- Check that the device is not in a draught or that the temperature setting ha
not been altered.
- There may be a fluctuation in the main power supply. If there is a problem
(
blocked thermostat...
), cut off the power to the device (
fuse, circuit breaker
)
for approximately 10 minutes and then switch it back on.
- If the phenomenon recurs frequently, have your electricity utility check the
power supply.
The device’s surface
is very hot.
It is normal for the device to be hot when it is operating; the maximum sur-
face temperature is restricted in accordance with the NF electrical perfor-
mance standard. However, if you think that your device is still too hot, check
that the output is suitable for the area of your room (
we recommend 100W /
m2
) and that the heater is not placed in a draught, which would interfere with
its self-regulation; also check that the installation guidelines have been fol-
lowed (
curtains, etc.
)
The device does not
follow its program-
ming instructions.
Ensure that the energy controller or programming unit is being used correct-
ly (
see the user’s manual
).
The heating light
E
and the consumption
indicator light
D
flas-
hes rapidly (
lit 0.5
seconds, unlit 0.5
seconds
).
The measurement sensor has deteriorated.
Your device’s absence detector is disconnected or is not working.
Contact your installer.
The functions other than absence detection still remain operational.
The heating light
E
flashes slowly (
lit
1
second, unlit
1
second
).
Your device’s potentiometer has deteriorated.
Contact your installer.
The airing detector
does not react
Your device’s environment may interfere with this function’s ability to react
(
e.g.: distance of the device from the window, the external temperature, the room’s
level of insulation, etc.
). During airing, switch the cursor to Stand-by mode .
