Troubleshooting
Malfunctions are often due to minor causes; please read the table below before contacting the after-sales
service. This can save you time and avoid unnecessary expenses.
Problem
The display of the control
box does not turn on.
The room temperature is
diff erent from that displayed
on the device.
The unit does not heat.
The device heats all the time
The unit does not heat
enough.
The device is slow to heat
up.
The device is very hot in
surface.
The last upper and lower
units are more lukewarm
than the rest of the unit
The device makes a liquid
noise when it is handled.
The device does not follow
the internal programming
commands.
The device does not follow
the commands of the pilot
wire.
Traces of dirt appear on the
wall around the unit.
Causes, Solutions
Check that the device is electrically powered. Check that the switch is in position I.
It is necessary to wait at least 6 hours for the temperature to stabilize.
It is possible to adjust the set temperature to the temperature measured in the room
(see "Calibration" in the Advanced Functions)
In programming mode, check that the heater is on a Comfort range.
Check power supply (circuit breaker)
Check the temperature of the room: if it is too high compare to the setpoint tempera-
ture, the unit does not heat.
Check programs.
Check that the device is not located in a draught (open door, cold air from the junction
box at the rear of the device, centralized mechanical ventilation) or that the setpoint
temperature has not changed.
In case of problems (thermostat blocked ...), cut the unit off (fuse, circuit breaker) for
about 10 minutes, and then on again.
Increase the setpoint temperature.
If set up is maximum, check the following:
 Check room temperature
 Check whether another heating mode exists in the room.
 Ensure that the device only heats the room (door closed).
 Check if the power of the heater is adapted to the size of the room (we recom-
mend averaged 125 W / m2 for a ceiling height of 2.50 m).
The electrical resistance heats the fl uid that is gradually and naturally circulating
inside the device. Due to the fl uid inertia properties, the device surface temperature
reaches an optimal level only after 15 min minimum, according to the room tempera-
ture during the heat up of the device.
It is normal that the device is hot when in use, even if the maximum surface tempera-
ture is limited in accordance with the NF standard Electricity.
The upper elements are not completely fi lled to allow for expansion of the working
fl uid. They heat only by conduction.
The lower elements channel the return of the fl uid which transmitted its heat.
During unpacking or installation, it is normal to hear the fl uid fl ow within the device.
Check the date and time are set.
Check that the device is in Program active mode.
Check that the value of the parameter program is "inactive".
Check that the pilot wire is connected.
Check the centralized manager and sent orders (see chapter: using a centralized
manager page 116)
In polluted atmosphere, dirt may occur on the air outlets of the device or wall. This is
related to the poor quality of the ambient air (cigarette smoke, candles, incense, fi re,
...). It is advisable in this case to verify the proper room ventilation (ventilation, air
input, etc ...).
