Definitions

• the invention relates to an electric heating system which has the features of the preamble of claim 1.
• Heating systems with electric heating bodies and room temperature controllers are known. On these controllers, a set temperature can be set which is compared with the actual temperature measured in a room to be heated.
• the control signals are transmitted wirelessly by the thermostats to the heating bodies or their control devices, for example by means of a radio remote control.
• the heating elements can be connected directly to the power supply via radio-controlled plugs or adapters, and the radio control of the room thermostats acts on the switch plugs to control switching on or off. shutdown of the heating bodies.
• the same source also describes the option of providing on the heating bodies themselves radio receiver control devices which provide direct control of the heating power as a function of the signals of the radio-transmitted thermostat.
• a unambiguous functional relationship must be established between a thermostat and the receiver provided on the heater and / or the controller by matching them to each other. This avoids in an environment of several premises that the heating bodies are inadvertently controlled by "foreign" thermostats.
• the object of the invention is, in a heating system having the generic characteristics, to provide a particularly simple and intelligible tuning to be used between a heating element or its individual control device with the receiver on the one hand, and a room thermostat on the other hand. According to the invention, this problem is solved with the features of claim 1.
• the features of the dependent claims provide advantageous developments of this invention. Taking into account a particularly obvious actuation, the learning operation (in "learn-enable" mode) with a view to establishing a unambiguous functional relationship between a thermostat arranged in a compact housing and an associated control device to a heating body, including the receiver, is, according to the invention, based on a mutual spatial or physical mutual. Therefore, in particular, it is essentially possible to avoid an erroneous agreement between a heating body and a
• the thermostat can be provided with an autonomous power supply (batteries, accumulators). Therefore, it is not connected to a physical conductor but is mobile and can therefore be placed anywhere in the room.
• the invention takes advantage of it.
• the direction in which the identification signals are transmitted is therefore basically indifferent, and it can therefore go from the thermostat to the control device / heating body or vice versa.
• the first possibility is preferred, however, because the thermostat necessarily includes an emitter for transmitting the heating or power control signals. This transmitter can advantageously also transmit the identification signals. Therefore, it is not excluded to use another transmitter or other means for the transmission of identification (system).
• This method is also advantageous because, if necessary, several heating bodies located in one or more rooms can be controlled by a single thermostat. Indeed, if in this case, we wanted to place in the thermostat an individual identification of each heater, they should have several memory locations that should be able to be interrogated individually. This could result in complicated and difficult to understand command for laypersons. On the other hand, if it is provided in each heating body a single memory location for the identification of a thermostat, it is very simple to establish an unambiguous working relationship between these two devices. As furthermore, the thermostat comprises in any case control elements for setting parameters, for example the set temperature, the on or off times, etc., these elements can advantageously also be used to activate the mode. transmitted to transmit the identification signals. Normally, this last operation does not occur very frequently.
• a special actuation for example the simultaneous depressing of two keys or the like, can trigger the transmission of the identification.
• This mode is preferably automatically limited to a predetermined time interval during which it is then necessary to bring the thermostat of the control device of the heating body.
• the identification signals will in any case also be appropriately associated with the normal control signals (for example superimposing or emitting them before or after them), so that the receiver provided in the control device "knows" that it is requested by the thermostat concerned. Therefore, even when the learning operation is activated, it is possible to simply transmit a "normal" command and power signal whose identification part is separated by filtration and kept in permanent memory.
• the location of which the thermostat must be approached for the learning operation will normally be located near the electrical connections (power) of the heating body that are provided anyway, when the receiver is placed directly on the heating body.
• the control device with the receiver is arranged separately from the heating element, for example in its power supply line and / or on the connection or connection box to which the heating element is connected, the control device shall be provided with a corresponding identification.
• approach sensitive switching devices allow the read operation.
• These heating bodies may be transparent and include in particular a limited connection zone visible from the outside. In a preferred embodiment of these heating bodies, this zone is also that from which the thermostat must be approached for the transmission of the identification signals. Special marking on an outer surface of the glass heater is then not necessary, even if the connection area is provided on the flat side not facing the user.
• the control device of each heating body is separated therefrom, preferably being disposed on the fixed connection location. In this case, the thermostat must be approached from a location of the control device possibly provided with a registration in order to introduce the mutual agreement.
• a transmission of the identification without contact it is obviously also possible to provide a transmission of the identification by contact (galvanic).
• non-volatile means in particular that the identification stored in memory is not lost in the event of a power failure or disconnection of the heating body of the network.

• the regulation element 4 receives setpoint signals from a receiver element 5.
• Control signals (here represented by an arrow) for maintaining a predetermined temperature of the room are sent without contact to the latter by a thermostat 6 or a transmitter 7 which is incorporated therein.
• the thermostat 6 has an independent power supply voltage (batteries or accumulators, for example) which is not shown here in detail. It also has a digital display 8 which presents information on the management of electric heating and which preferably works as multifunction display. Below the display 8 are provided several actuating elements, for the manual adjustment for example of the set temperature, the date, the time, etc. The associated switching elements are imposed by the state of the art and are therefore not shown or explained in more detail. Finally, the thermostat 6 still contains a permanent magnet 9.

• the thermostat 6 or, as the case may be, its emitter 7 are connected in the emission mode of its characteristic. As already indicated, this can be activated by a special actuation, explained in the instructions for use, of one or more control elements of the thermostat 6.
• the thermostat 6 is then brought closer to the magnet 9 of the mark 12 of the heating body 1 or the control device S and thus the switch 10. The latter closes; this activates a "learn-enable" mode of the memory element 11.

• the output signal of the control element memory 11 which corresponds to the identification of the thermostat is also applied.
• the comparison stage 14 must therefore check whether the control signals which are brought to it have a corresponding identification part, in other words, if they come from the "correct” thermostat. Signals that come without contact from a thermostat not registered in the memory element 11 are ignored by the control of the heating element 1.
• the "learn-enable" mode of the memory element 11 can also be activated by other means, for example by inductive or capacitive coupling.
