1. Electrical connection for wireless thermostat control

Any work on an electrical installation must be carried out by a professional.


You have chosen a wireless temperature management solution, which also aims to hide the heater’s power supply wire. In this case, the power supply to the heater must be located behind the heater! The location does not matter (as long as it is not located where you are going to fix the 2 wall mounting plates, if not already done – see manual). The power cable of the heater is long enough to reach any power supply area behind it.

The final goal is to insert the radio receiver into the socket. Of course, if your socket has a front panel, you must remove it in order to insert the receiver.

Steps prior to connection

  • You have already attached the 2 wall mounting plates supplied with your heater (see manual).
  • Switch off the power.
  • If necessary, remove the front of your wall socket. When this is done, your socket box is empty with only the 3 wires (Neutral, Live, Earth) ready to be connected. Your socket cover is no longer of any use to you, you can remove it (it will not be put back on!).
  • Using a pair of pliers, cut the power cable to the heater, making sure that you leave enough room to hook and unhook it if you need to in the future. If you have left too little margin, you will not be able to hook and unhook the heater without the risk of tearing the wires. PS: you can also simply unscrew the extra-flat plug from the heater to reveal the 3 cables to be connected (Neutral, Live, Earth).
  • You are ready to connect the wires between the heater, the receiver and the power supply. Follow the diagram below.

Failure to follow the connection diagram will not only result in a loss of warranty (because of the risk of damaging the receiver) but also in safety risks.

The 3 power supply wires are marked as follows: N=Neutral=Blue, L=Live=Black or Red, T=Earth=Green-Yellow. You need a 4-slot barrier strip/wago terminal block or 4 mini wago terminal blocks.

  • Using a wago terminal block, connect the Neutral wire (blue) of the power supply with:
    • the Neutral (blue) wire of the heater
    • the N of the receiver (blue).
  • Using a wago terminal block, connect the Live wire L (black or red) of the power supply and the Live L (black) of the receiver.
  • Using a wago terminal block, connect the brown wire of the receiver with the Live wire L (black or red) of the heater.
  • Do not forget to connect the Earth wire (green-yellow) of the heater with the one of the power supply (not present on this diagram) using a wago terminal block.

The connection is complete. You can turn the power back on.

2. Setting up the wireless thermostat

3. Pairing operation between the thermostat and the receiver

This is a mandatory step. If this is not done, the heater will not receive commands from the thermostat.

Read the entire procedure before carrying it out.

On the THERMOSTAT and then on the RECEIVER perform the following actions:

Procedure in video

The procedure is very simple, but please note the following 2 points:

  • If you press and hold the receiver for too long you will put the receiver in a different mode than learning mode. Therefore the pairing operation (link or coupling between the thermostat and the receiver) will not work. You will have the impression that the heater will not respond to the thermostat’s commands, which is the case!
  • also the manipulation on the thermostat must be done immediately after the step on the receiver. If you are (much) too slow, the receiver will lose its «learning» state and will not be able to perform the pairing.

These control accessories are high-quality electronic equipment. Of course, a breakdown is always possible.

However, as they are (very very) rare, before declaring a failure, please repeat the operation, it will (very) probably work :))!

4. Functional tests

Ignition test:

On the thermostat, set a target (or desired) temperature well above the room temperature displayed by the thermostat (e.g. 28°C) by pressing + several times. Wait between 30 seconds and one minute. The receiver should switch on (you will hear a significant click).

Extinction test:

On the thermostat, set a target (or desired) temperature well below the room temperature displayed by the thermostat (e.g. 10°C) by repeatedly pressing – . Wait between 30 seconds and one minute. The receiver should stop (a small, significant click is heard).



1) Replace the batteries in the thermostat with new ones and ensure that the thermostat and receiver are in the same room!

2) Repeat the initial step of setting up the thermostat (see above).

Note: wait the necessary time (about 1 minute) between each command transmitted by the thermostat before measuring its effects.

*** Your equipment: Control Pack n°8 ELB = Built-in Radio Receiver/Switch + Wireless Thermostat ***

Pour rappel, les documents dont vous avez impérativement besoin pour faire fonctionner vos appareils (livrés dans les colis avec les accessoires) :


  • Symptom: The heater does not respond to the thermostat commands AND it has never turned on!

With the + button set a high temperature (higher than the room temperature indicated on the thermostat, e.g. 27°C). Within a minute the heater should start (you can hear a small click indicating the triggering of the receiver to switch on the heater). Of course the heater takes time to heat up, so you should wait 2-3 minutes to feel the surface heating up.

  • It doesn’t work > Possible causes:
    • A) the initial pairing operation (invisible link between the thermostat and the receiver) has never been performed or has not not been performed correctly (strictly observe the pressing times and steps indicated). Solution: carry out the operation as indicated. If the radiator has never been switched on, this assumption is VERY likely.
    • B) If, despite trying, you have not succeeded in the previous step, change the batteries. Basic batteries can deteriorate in their original packaging when not in use.
    • C) Check that the connections are correct and that there is no false contact on the terminal.
    • D) The thermostat is out of range of the receiver – they are not communicating (too far away, receiver placed behind a wall, PLC socket or interference from nearby radio devices, etc.). Place the receiver within communication range as indicated in the manual. Disconnect other interfering elements (PLC, radio-controlled socket, etc.).
    • E) Finally, if it still does not work, it may be that the thermostat is not in the right control mode (you think it is in manual mode when it is in AUTO for example).


  • Symptom: The heater is still ON even if the stop has been set on the thermostat
  • Possible causes > incorrect use of the thermostat:
    • you are probably in the wrong mode, i.e. not the one you want (e.g. on auto=recorded programs). The heater is working because the room temperature measured is lower than the target temperature set in the thermostat according to the mode it is in. Refer to the detailed manual of the thermostat and choose the mode corresponding to your expectations (auto=recorded programs, manual, frost protection).
    • very simple solution is to set the thermostat to OFF mode
    • Finally, if it still doesn’t work, repeat the pairing procedure.


  • Symptom: The control of my heater has already worked but the heater does not heat up or not when I want it to
  • Possible causes:
    • The batteries in the thermostat are worn out and need to be replaced. The batteries supplied with the thermostat are basic, please feel free to replace them with high capacity batteries.
    • The thermostat is not in the mode you think it is, so the heater is not producing the expected effects (auto=saved programs, manual, off). Common cause, you think you are in Manual mode when you are in ‘AUTO’.
    • You are using the weekly program, but you forgot to set the hour/minute/day on the thermostat. See manual.
    • The thermostat has detected an open window = the open window function has switched off the heater. Be careful not to place the thermostat in a draughty area, which can disturb its operation. You can also read the rules for the installation of a room thermostat


  • Symptom: The heater runs from time to time when it should not (summer, other)
  • Possible causes:
    • The batteries in the thermostat have been removed or need replacing. The batteries supplied with the thermostat are basic, please feel free to replace them with high capacity batteries.
    • The thermostat is out of reach (distance, partition) of the heater (and therefore of the receiver).

=> The receiver will automatically go into a degraded mode. After 3 hours of communication failure, the heater will run for 1-2 minutes every 10 minutes. In the off-season, we advise you NOT to remove the batteries from the thermostat. You can simply set the heater to OFF mode. This way, if the room temperature is above 3°C, the heater will not operate..

=> Please note. If the batteries in the thermostat stopped working when the heater was on, the heater may still be working. Replace the batteries with new ones promptly.


  • Symptom: The Ertr message appears on the thermostat display

  • Possible causes:
    • If the problem appears when you have just completed the pairing, then restart the pairing from 0.
    • If the problem occurs after a certain time:
      • change the batteries if the batteries to be replaced symbol is displayed.
      • move the thermostat closer to the receiver. Wait a few minutes to see if the error disappears. Change the batteries if necessary.
      • on the receiver, if the green LED1 flashes, the code in the receiver has been deleted and the pairing must be repeated.
      • on the receiver, if the green LED1 is permanently lit, remove the batteries from the thermostat for 2 minutes. Turn off the power to the receiver for 2 minutes. Turn the power back on and put the batteries back into the thermostat. The 2 devices should automatically re-pair after a certain period of time.

=> Please note. The number behind Ertr (e.g. 1) indicates the number of the receiver with which there is a communication problem.

BEFORE CONTACTING OUR SERVICE: 1) Change the batteries in the thermostat with new ones 2) Repeat the initial step of pairing the thermostat and receiver.

Indeed, failures are extremely rare. In 95% of cases, the problem is that the pairing step was not carried out at all, or was not carried out properly (not respecting the pression times). It is therefore useless to send the equipment back to us for exchange, as the new equipment will produce the same effects. Finally, it is always possible that the electric connection has been poorly made.

To rule out any problems with the heater, you can simply plug its power cable directly into a wall socket. Wait a few minutes and check that the surface of the heater becomes warm. If it does not, contact our customer service.

Removing the pairing between thermostat and receiver(s)

Please note. In case several receivers are paired to the same thermostat, it is not possible to remove the link with only one receiver. The link removal will work for all receivers.
