ENCOUNTERED
The radiator does not
heat up.
The radiator does not
warm the bathroom en-
ough.
The radiator heats all
the time.
The surface of the radia-
tor is very hot
Dirty marks appear on
the wall around the
radiator
The top and bottom
rails are cooler than the
rest of the heated towel
rail
- Ensure that the mains switches are turned on, and that the load-shedding
device (if you have one) has not cut off the power supply to the heated
towel rail.
- Check the ambient temperature of the room: if it is too high, the heating
indicator
will not come on and the heated towel rail will not heat up.
- Adjust the programmed value (see the chapter on Use)
- Turn your heater off then on again, using the knob:
- Adjust the programmed value (see the chapter on Use)
- If the temperature is turned up to the maximum (30°C), check the follo-
wing points:
• Check that there is no other heater in the room.
• Ensure that your heated towel rail is only warming the one room (i.e.
the door is closed).
• Have someone check the supply voltage of the radiator.
• Check that the power of your heated towel rail is suitable for the size
of your room (on average we recommend 100W per cubic metre).
- Check that the control unit is not placed in a draught (door open close
by) or that the temperature setting has not been changed.
- There may be a hitch in the electrical supply. If this is the problem (a
blocked thermostat for instance), switch off the supply to the heated towel
rail by removing the fuse or switching off the trip-switch for about 10 mi-
nutes, then switch it back on again.
- If this happens frequently, hove your power company check the supply.
It is normal that the heated towel rail will get hot when it is running, but
the maximum surface temperature is limited by the French Electricity Per-
formance standard. However, if you judge that your radiator is still too
hot, check that the power is suitable for the size of your room (we re-
commend 100W per cubic metre) and that the heated towel rail is not in
a draught which will disturb its setting.
These marks depend entirely on the quality of the air (candle smoke, ciga-
rette smoke, poor ventilation, etc).
- The top rails are not completely filled, to allow for expansion of the
thermodynamic fluid. They only heat by conduction.
- The lower rails channel the return of the fluid as it cools down.
