Installation of an electric radiator with controlled inertia controlled by power line

The technology of "power lines" allows to communicate instructions to the device via the existing power network, so without additional wire, from a transmitter located "in ambience". It can be a central wall box (BMC) affixed to a wall (TDM kit + programming card) and able to control one or more devices for the same zone, or even to control the devices of several zones (orders different). It may also be a radiator equipped with a TDM interface box + programming card, able to control other devices "slaves" (receiving his orders) on the same area. It is sufficient that these devices are mounted with TDM cable outlets, obviously different from the standard cable outlets. This technique allows the electronic programming of electric heaters via the normal power supply circuit of the devices, without pilot wire. This system is suitable for houses built more than fifteen years ago and therefore not benefiting from electrical installation with pilot wire: the electronic programming of electric heaters simply passes through the wires of the normal power supply circuit of the appliances.

Hanging the device

Standard power supply of a Class II device

Standard power supply of a Class II device

1. The device we have set up operates autonomously, adjustable directly on its own control box. Class II device, it was not connected to the ground. Its power supply is therefore done by direct connection of phase and neutral to the mains line under protection of a standard cable outlet (photo). To integrate it into a set of appliances meeting the same criteria of need and thus create a "zone of heating" identity in a part of the house (for example the rooms), it is necessary to equip it with an interface provided with a programming card and make some modifications of its mode of feeding.

2. In order to unhook the device from its support, it is first necessary to unlock the locking device by bringing the flat part of the locking screw into contact with the sheet on the back of the radiator. Use a flat-blade screwdriver.

3. Raise the radiator to unhook it from the high mounting points of its bracket. It is still maintained by the lower fixing points and the incline chains. Unhook the chains, lift the unit and place it on the ground. It is equipped with feet that allow it to stand alone.

4. Present the back of the radiator to have a convenient access to the housing provided for the interface and then release with the flat of a screwdriver, the protective cover of the contact blades of the box.

5. Place the case in its slot. The contact blades that it presents must never be deformed. The lower edge of the housing carries the two fixing screws, a spare fuse and a locking bolt of the system (to be put in place to prevent the children from disrupting the programming).

6. Use only the two screws provided and clipped on the base of the case to fix it to the back of the radiator. This is an express recommendation from the manufacturer.

7. Finish fixing the case by screwing it carefully. Working on plastic materials, a faulty screwing quickly destroys the screw threads made in this material.

8. Here is the map that will control the operation of the radiator according to the programming you have chosen and which you have calibrated the card. The radiator keypad (above) will no longer have priority programming. It will not find it in case of general deprogramming of the card or its lack of its support-box.

9. Locate the irregular profile of the card in its thickness to insert it correctly into the box. It is the back of the card which must remain partly apparent; it presents a "cartelette" which takes as a reminder the diagram and the indications of adjustment and operation. A locking device (child safety bolt) can prevent its extraction.

10. Before changing the radiator power supply, turn off the power to the main meter and signal your intervention if the unit is remote (cellar or garage). Remove the cover of the junction box and remove the connections.

Disconnecting power supplies

11. Disconnect all wires and keep only the neutral wire (blue) and the phase wire (brown or red), the ground wire being neutralized. (We had when installing the radiator, a recent power line with pilot wire).

12. The TDM cable outlets are in two parts. The upper part, which carries the terminal block on its back, is cut to allow its attachment to the bases of the flush-mounted junction boxes. The lower part, which has a cable clamp on its back, is clipped on the other part and closes with two screws.

13. The terminal block is centered at the center of the black pilot wire and the blue and brown phase neutral wires of the radiator power cable.

14. Tighten the wires in place. You must use a Phillips screwdriver. Note on the back of the terminal block, the wire identification symbols: FP for pilot wire, N2 for neutral radiator and L2 for radiator phase and then at the ends, N1 neutral sector and L1 phase sector corresponding.

16. Fix the upper part by screwing onto the base of the flush-mounted box after inserting the connected terminal block. Make sure that the wires inside the base are properly positioned before screwing.

18. Reposition the radiator on its support in the reverse order, the operations of the beginning. Note the lateral position of the head of the programming card for easy access.

19. Do not forget to hang the 2 safety chains on each end of the radiator and to lock its final positioning by manipulating the 2 heads of plastic screws with irregular sides as done in picture 2.

20. The two-part cover of the TBM cable outlet is used to identify a power-wired device since the pilot wire programming is done with a standard cable output (in one block: photo 1).
