Heating body
The device doesn't heat:
- Check the position of the circuit breaker/power supply protection fuse in
your fuse board.
- Check the active operating mode
mode" or in Auto mode, with an imposed stop order by the energy man-
ager
(see page
18).
- Check the ambient temperature using a thermometer: if it is elevated,
the device has reached the desired temperature setting, therefore it is
normal that it doesn't heat more.
- Switch the power off for 5 seconds at the mains supply then switch back
on again.
The room temperature is not high enough, the device is not providing
enough heat:
- Check the active operating mode
protection, Standby or in Auto mode, with an imposed stop order by the
integrated programming or the energy manager. Activate the perma-
nent Comfort mode.
- Check the active temperature setting and increase it if necessary
10).
- Check the adjustment of the set temperature limit
- If the problem persists, check the radiator sizing compared with the
room dimension and insulation.
The device heats continuously and is hot on the surface:
- Check that the device is not influenced by an airstream.
- Check that the set temperature has not been changed.
- In operation, it is normal that the device surface is hot.
- If the problem persists, check the radiator sizing compared with the room
dimension and insulation.
Several situations can generate a slight metallic slam.
- The device is fixed on an irregular wall.
- The device is fixed on an uninsulated wall.
- The device is in a stream of cold air.
- The device is badly positioned in the wall-mounting brackets.
- Heat up or sudden temperature change.
Important: Failure of the internal thermal limit due to overheating
caused by the user eg covering with clothing is not covered by war-
ranty.
Controller
The ambient temperature is lower than the set temperature:
- Check the programming mode. You may be in Eco period.
- Check the time setting.
- Otherwise, switch the power off for 5 seconds at the mains supply circuit
then switch back on again.
The ambient temperature measured by a thermometer doesn't corre-
spond to the set temperature after several hours.
- An offset is always possible, you can refine the device setting
27).
The device does not heat while the heating indicator is on:
- The heating symbol is lit on the display, the unit is cold, contact your in-
staller.
The device does not automatically lower the temperature in the ab-
sence period:
- Check that the occupancy detection is enabled
- Check that nothing disturb the operation of the occupancy detection
(see page 4 et
17).
After a subsequent temperature drop at the opening of a window, the
device will not enter in Frost protection mode:
- Check that the automatic mode of the open window detection is ena-
bled
(see page
23).
- Check the location of your radiator
- Check that the temperature difference between the room air and outside
air is significant.

IAGNOSIS SUPPORT
(see page
8), you could be in "Standby
(see page
8), you may be in Eco, Frost
(see page
(see page

(see page

(see page

The device automatically enters in Eco or Frost protection mode in
your
presence and closed windows:
- If the pilot wire is connected to a central programming via pilot wire,
check the programming of the central.
- Disable the automatic open window detection mode
- Disable the occupancy detection
The device is in self-programming mode and you observe a delay be-
tween the active mode Comfort or Eco and your requirement:
- The self-programming works by detecting and learning of your occu-
pancy cycles, the device defines the future program by adapting to the
different observations made in occupancy in the previous week. If your
lifestyle is very irregular, for example every week is different, it is impos-
sible to determine exactly your requirements in advance. Self-program-
ming, such as weekly and daily programming, can never fully match. In
this case, it is advisable to use only the presence/absence detection and
to program your device in permanent Comfort
- The optimisation function can generate slight offsets to guarantee the
level of comfort at the right time or to save energy by slightly anticipating
an Eco passage.
- Check that the presence/absence detector is not disturbed or blocked by
an external source
(see page 17).
The device is self-programmed but no period is programmed (ECO
registration is displayed on the display):
- Check that the presence/absence detector is not disturbed or blocked by
an external source
(see page
The unit is in self-programming mode but the ambient temperature is
not sufficient at the beginning of the period. Comfort:
- Check the Eco lowering level
- If it is below -3.5°C, For example -5°C, the difference between the Com-
fort and Eco setpoint temperature is too high, which explains the per-
ceived temperature difference at the beginning of the Comfort period.
It is therefore recommended to set it to its initial value -3.5 ° C.
- If the Eco lowering level is -3.5°C, set it to -2°C to reduce the difference
between the Comfort and Eco setpoint temperatures.
The device is in Auto mode, remotely controlled by an energy manag-
er or programmer but the programming orders are not executed by
the device:
- Make sure the energy manager or programmer is in good condition, refer
to the user instructions.
- Change the batteries of the energy manager or the programmer if this
one contains it.
No symbol appears on the display screen.
- Check the position of the circuit breaker/power supply protection fuse in
your distribution/fuse board.
You want to increase or decrease the set temperature but pressing a
key on the keyboard has no effect:
- If the padlock symbol is displayed, the keypad lock is enabled.Unlock the
keypad as shown in the manual, child anti-tamper section
- Check the changes, restrictions temperature settings
You made a mistake while setting the advanced settings.
- Just restore factory settings – see the "Restoring factory settings" para-
graph
(see page
26). This will erase any programmes that you would have
implemented.
If the problem persists, then contact your reseller.
