Problems Check
The device does not
heat
- Check that the programming unit is in Comfort mode. .
- Check that the premise circuit breakers are triggered or that the load shedder (if you
have one) has not interrupted the device’s power supply.
- Check the air temperature in the room.
The device heats all
the time
- Make sure that it is not in a draft and that the temperature setting has not been chan-
ged. This unit with electronic control is equipped with a microprocessor that can be dis-
tribued by some severe mains voltage disturbances (outside EC standards defi ning the
disturbance protection level). If there are any problems (thermostat blocked, etc.) switch off
the unit power supply (fuse, circuit breaker, etc.) for about 5 minutes to allow the unit to
start again.
The device’s surface
is very hot
It is normal for the device to be hot when it is operating. The maximum surface tempe-
rature is restricted in accordance with the NF Electricité Performance standard. However,
if you think that your device is always too hot, check that the output is suitable for the
area of your room (we recommend 100W / m
2
) and that the device is not placed in a
draught, which would disrupt its setting.
The device does not
follow the program-
ming instructions
- Ensure that you use the programming unit correctly (refer to the instructions manual), that
the programmer is correctly lodged in its housing and that it is operating normally (check
the condition of the batteries).
This device is electronically controlled and its microprocessor can be affected by significant local interferences
(outside the EU norms defining the level of protecton against interference).
If a problem should arise (locked thermostat, etc), cut the power supply to the device (fuse, circuit breaker, etc) for
approx. 10 minutes to reset the device.
If the problem recurs frequently, have your electricity supply checked by your electricity supplier.
2/Maintenance
To maintain the performance of the device, the upper and lower grills must be cleaned with a vacuum clener or
a brush approximately twice per year. Do not use abrasive products.
