Die folgenden Erläuterungen beziehen sich auf ein Heizsystem. Für ein Kühlsystem sollen die Ausführungen aber entsprechend gelten.The following explanations relate to a heating system. However, the statements should apply accordingly to a cooling system.

Bei handelsüblichen Regelungssystemen für Flächenheizungs- oder Kühlungssysteme wird die an den einzelnen Heizkreisen auftretende Temperaturdifferenz zwischen Vorlauf- und Rücklauftemperatur (Spreizung) gemessen und zur Optimierung des Regelverhaltens verwendet. Diese Optimierung kann dazu dienen, Fehler in der hydraulischen Abstimmung der Anlage zu kompensieren, das Aufheizverhalten zu verbessern oder eine gewünschte Mindestbodentemperatur einzuhalten. Die gemessene Spreizung kann dabei zusätzlich zu der ebenfalls gemessenen Raumtemperatur eingesetzt werden, aber auch als alleinige Regelgröße.With commercially available control systems for surface heating or cooling systems, the temperature difference between the flow and Return temperature (spread) measured and used to optimize the control behavior. This optimization can be used to compensate for errors in the hydraulic coordination of the system, to improve the heating behavior or to maintain a desired minimum floor temperature. The measured spread can be used in addition to the room temperature, which is also measured, but also as the sole control variable.

Die Messung der Temperaturen am Hydraulikverteiler geschieht über Anlege- oder Tauchtemperaturfühler, die mit der zentralen Regeleinheit über Messleitungen verbunden sind. Die Zuordnung der an den einzelnen Heizkreisen installierten Sensorik (z. B. der Heizkreis-Temperaturfühler) auf die Kanäle der Regeleinheit und somit auf die zu regelnden Räume, geschieht dabei entweder durch die direkte Verdrahtung der Fühler mit den für die einzelnen Räume vorhandenen Anschlüssen oder durch Zuweisung während der Inbetriebnahmesequenz. Sowohl bei der Verdrahtung der Fühler als auch bei der Zuweisung der Fühler im Zuge der Inbetriebnahmesequenz können Zuordnungsfehler auftreten, die den gewünschten Optimierungseffekt dieser zusätzlichen Sensorik beeinträchtigen oder ins Gegenteil umkehren können.The temperatures at the hydraulic distributor are measured using contact or immersion temperature sensors that are connected to the central control unit via measuring lines. The assignment of the sensors installed on the individual heating circuits (e.g. the heating circuit temperature sensor) to the channels of the control unit and thus to the rooms to be controlled is done either through the direct wiring of the sensors with the connections available for the individual rooms or by assignment during the commissioning sequence. Allocation errors can occur both when wiring the sensors and when assigning the sensors in the course of the commissioning sequence, which can impair the desired optimization effect of this additional sensor system or reverse it.

An dieser Stelle setzt die vorliegende Erfindung ein, der die Aufgabe zugrunde liegt, ein Verfahren zur Zuordnung eines Heizkreis-Temperaturfühlers eines Heiz- und/oder Kühlsystems zum betreffenden Heizkreis oder zur Überprüfung der Zuordnung eines Heizkreis-Temperaturfühlers eines Heiz- und/oder Kühlsystems zum betreffenden Heizkreis zur Verfügung zu stellen, das die Nachteile des Stands der Technik überwindet. Insbesondere soll das erfindungsgemäße Verfahren eine sichere Zuordnung der einzelnen Heizkreise auf die Kanäle der Regeleinheit und somit auf die zu regelnden Räume oder im Bedarfsfall eine sichere Überprüfung dieser Zuordnung sicherstellen. Darüber hinaus liegt die vorliegende Erfindung auch in der Bereitstelllung eines Heiz- und/oder Kühlsystems, das zur Durchführung des erfindungsgemäßen Verfahrens ausgebildet ist, sowie in einem Computerprogrammprodukt einer Regeleinheit zur Steuerung eines Heiz- und/oder Kühlsystem, das die Operationen zur Durchführung eines erfindungsgemäßen Verfahrens in der Regeleinheit bereitstellt.At this point, the present invention, which is based on the object, a method for assigning a heating circuit temperature sensor of a heating and / or cooling system to the relevant heating circuit or for checking the assignment of a heating circuit temperature sensor of a heating and / or cooling system to to provide relevant heating circuit available that overcomes the disadvantages of the prior art. In particular, the method according to the invention is intended to ensure a reliable assignment of the individual heating circuits to the channels of the control unit and thus to the rooms to be controlled or, if necessary, a reliable check of this assignment. In addition, the present invention also lies in the provision of a heating and / or cooling system, which is designed to carry out the method according to the invention, as well as in a computer program product of a control unit for controlling a heating and / or cooling system that performs the operations for carrying out a method according to the invention Provides method in the control unit.

Vorteilhafte Ausführungsformen der vorliegenden Erfindung sind in den abhängigen Ansprüchen beschrieben.Advantageous embodiments of the present invention are described in the dependent claims.

Gemäß der vorliegenden Erfindung wurde erkannt, dass eine sichere Zuordnung der einzelnen Heizkreise auf die Kanäle der Regeleinheit dadurch gewährleistet werden kann, dass über einen Heizkreis-Temperaturfühler eine Temperaturänderung des Temperiermediums in dem Heizkreis, die auf das Öffnen eines diesem Heizkreis zugeordneten Ventils zurückzuführen ist, detektiert wird. Nach dem Öffnen des Ventils dieses Heizkreises wird nach einer Zeitspanne, die von der Länge des Heizkreises und der Temperatur der Speichermasse, in die das Rohr eingebettet ist, abhängt, eine Veränderung der Temperatur des Temperiermediums beispielsweise in der Rücklaufleitung zu erkennen sein. Diese Temperaturänderung wird vom Heizkreis-Temperaturfühler diese Heizkreises erkannt und ein entsprechendes Signal an die Regeleinheit übermittelt; die dem Signal entsprechende Information wird dann durch die Regeleinheit gespeichert. Auf diese Weise kann dieser Heizkreis-Temperaturfühler dem entsprechenden Heizkreis und damit dem entsprechenden Raum zugeordnet werden. Beispielsweise bei der Inbetriebnahmesequenz der Regeleinheit kann so die Fühlerzuordnung einfach und sicher erfolgen. Gleichermaßen kann im laufenden Betrieb der Anlage durch dieses Verfahren eine in der Regeleinheit gespeicherte Zuordnung der Heizkreis-Temperaturfühler auf die Kanäle der Regeleinheit überprüft und im Bedarfsfall angepasst werden. Durch die Anwendung des erfindungsgemäßen Verfahrens entfällt die fehleranfällige und zeitaufwendige Zuweisung der Sensorik. Darüber hinaus können bei bereits erfolgter Zuweisung Fehler, die bei der Zuweisung gemacht wurden, korrigiert werden. Die Positionierung der Heizkreis-Temperaturfühler in den einzelnen Heizkreisen ist beliebig und kann zeitlich in beliebiger Reihenfolge erfolgen; auch eine Codierung der Heizkreis-Temperaturfühler ist nicht erforderlich.According to the present invention, it was recognized that a reliable assignment of the individual heating circuits to the channels of the control unit can be ensured that a temperature change of the temperature control medium in the heating circuit, which can be attributed to the opening of a valve assigned to this heating circuit, via a heating circuit temperature sensor, is detected. After opening the valve of this heating circuit, after a period of time that depends on the length of the heating circuit and the temperature of the storage mass in which the pipe is embedded, a change in the temperature of the temperature control medium, for example in the return line, can be seen. This temperature change is recognized by the heating circuit temperature sensor of this heating circuit and a corresponding signal is transmitted to the control unit; the information corresponding to the signal is then stored by the control unit. In this way, this heating circuit temperature sensor can be assigned to the corresponding heating circuit and thus to the corresponding room. For example, during the commissioning sequence of the control unit, the sensor can be assigned easily and safely. Equally, during ongoing operation of the system, this method can be used to check an assignment of the heating circuit temperature sensors stored in the control unit to the channels of the control unit and, if necessary, to adjust it. The use of the method according to the invention eliminates the error-prone and time-consuming assignment of the sensor system. In addition, if the assignment has already taken place, errors that were made during the assignment can be corrected.

Vorzugsweise handelt es sich bei dem erfindungsgemäßen Heiz- und/oder Kühlsystem um Flächenheizung, insbesondere eine Fußbodenheizung/-kühlung oder eine Freiflächenheizung/-kühlung. In einem solchen System wird das Temperiermedium den Heizkreisen zum Kühlen/Heizen zugeführt. Bei der Temperiermedium kann es sich beispielsweise um Wasser oder ein anderes geeignetes flüssiges Medium handeln. Dem Temperiermedium kann z. B. Glykol zugesetzt sein. Fußbodenheizung/-kühlung bedeutet, dass die Heizschleifen beispielsweise im Estrich unter dem Fußboden verlaufen sind. Die Heizschleifen können auch in einer anderen geeigneten Struktur installiert sein. So können die Heizschleifen auch in der Wand oder Decke installiert sein. Alternativ kann das erfindungsgemäße Heiz-und/oder Kühlsystem auch als Heizkörpersystem ausgebildet sein.The heating and / or cooling system according to the invention is preferably surface heating, in particular underfloor heating / cooling or open surface heating / cooling. In such a system, the temperature control medium is fed to the heating circuits for cooling / heating. The temperature control medium can be, for example, water or another suitable liquid medium. The temperature control medium can, for. B. glycol may be added. Underfloor heating / cooling means that the heating loops have run in the screed under the floor, for example. The heating loops can also be installed in any other suitable structure. The heating loops can also be installed in the wall or ceiling. Alternatively, the heating and / or cooling system according to the invention can also be designed as a radiator system.

Die Regeleinheit des erfindungsgemäßen Heiz- und/oder Kühlsystems umfasst vorzugsweise eine Einrichtung, um die gewünschten Funktionen ablaufen zu lassen. Zum Beispiel berechnet der Funktionsblock der Regelungssoftware, der für einen Regelkanal der Regeleinheit, und damit für einen zu regelnden Raum oder Bereich zuständig ist, das Regelsignal auf Grundlage des Sollwerts der Raumtemperatur, der tatsächlichen Raumtemperatur und der für die Erzielung des gewünschten Sollwerts benötigten Energie. Die Zuführung der Energie geschieht vorzugsweise unter Verwendung eines pulsbreitenmodulierenden Verfahrens. Dabei wird innerhalb einer Zykluszeit, deren Länge an das zu regelnde Heiz-und/oder Kühlsystem angepasst ist, das Ventil für einen durch die Regelungssoftware errechneten Prozentanteil der Zykluszeit geöffnet. Bei diesem Verfahren kann der Antrieb, der das Ventil am Heizkreisverteiler betätigt, auf einfache Weise für diesen Prozentanteil der Zykluszeit eingeschaltet werden, während er für den restlichen Prozentanteil der Zykluszeit ausgeschaltet bleibt.The control unit of the heating and / or cooling system according to the invention preferably comprises a device to allow the desired functions to run. For example, the function block of the control software, which is responsible for a control channel of the control unit, and thus for a room or area to be controlled, calculates the control signal based on the setpoint of the room temperature, the actual room temperature and the energy required to achieve the desired setpoint. The energy is preferably supplied using a pulse-width modulating method. In this case, within a cycle time, the length of which is adapted to the heating and / or cooling system to be controlled, the valve is opened for a percentage of the cycle time calculated by the control software. With this method, the drive that operates the valve on the heating circuit distributor can easily be switched on for this percentage of the cycle time, while it remains switched off for the remaining percentage of the cycle time.

In bevorzugten Ausführungsformen des erfindungsgemäßen Verfahrens werden die Stufen (i) bis (iv) hintereinander für mehr als einen Heizkreis durchlaufen, insbesondere für alle Heizkreise mindestens einmal. Auf diese Weise geschieht die Zuordnung bzw. die Überprüfung der Zuordnung der Heizkreis-Temperaturfühler auf die Kanäle der Regeleinheit für mehr als einen der Heizkreise des erfindungsgemäßen Heiz- und/oder Kühlsystems. Insbesondere bei der Initialisierungssequenz der Regeleinheit ist es sinnvoll, die Stufen (i) bis (iv) für jeden der Heizkreise mindestens einmal durchzuführen.In preferred embodiments of the process according to the invention, stages (i) to (iv) are run through in succession for more than one heating circuit, in particular for all heating circuits at least once. In this way, the assignment or the checking of the assignment of the heating circuit temperature sensors to the channels of the control unit for more than one of the heating circuits of the heating and / or cooling system according to the invention takes place. In the case of the control unit's initialization sequence in particular, it makes sense to carry out steps (i) to (iv) at least once for each of the heating circuits.

In weiteren bevorzugten Ausführungsformen des erfindungsgemäßen Verfahrens wird eine in der Regeleinheit gespeicherte fehlerhafte Zuordnung mindestens eines Heizkreis-Temperaturfühlers zum betreffenden Heizkreis korrigiert. Der Regeleinheit des erfindungsgemäßen Heiz- und/oder Kühlsystems wird für den betreffenden Heizkreis-Temperaturfühler ein Signal übermittelt, das diesen einem anderen Kanal der Regeleinheit zuordnet. Die Regeleinheit speichert diese Information und korrigiert so die fehlerhafte Zuordnung. Hinsichtlich des erfindungsgemäßen Heiz- und/oder Kühlsystems kann es günstig sein, wenn der Vorlauf-Temperaturfühler und die Heizkreis-Temperaturfühler durch einzelne Leitungen, durch einen Bus, durch ein Funksystem oder durch Kombinationen der genannten Verbindungsarten mit der Regeleinheit verbunden sind.In further preferred embodiments of the method according to the invention, an incorrect assignment of at least one heating circuit temperature sensor to the heating circuit in question, stored in the control unit, is corrected. A signal is transmitted to the control unit of the heating and / or cooling system according to the invention for the relevant heating circuit temperature sensor which assigns it to another channel of the control unit. The control unit saves this information and corrects the incorrect assignment. With regard to the heating and / or cooling system according to the invention, it can be advantageous if the flow temperature sensor and the heating circuit temperature sensor are connected to the control unit by individual lines, by a bus, by a radio system or by combinations of the types of connection mentioned.

Um eine Nachrüstbarkeit des erfindungsgemäßen Heiz- und/oder Kühlsystems zur Durchführung des erfindungsgemäßen Verfahrens zu gewährleisten, ist es bevorzugt, wenn die Regeleinheit modular aus einer Haupteinheit und einer Zusatzeinheit aufgebaut ist, wobei die Zusatzeinheit den Vorlauf-Temperaturfühler und die Heizkreis-Temperaturfühler umfasst und über eine Kommunikationsleitung mit der Haupteinheit verbunden ist.In order to ensure that the heating and / or cooling system according to the invention can be retrofitted to carry out the method according to the invention, it is preferred if the control unit is modularly constructed from a main unit and an additional unit, the additional unit comprising the flow temperature sensor and the heating circuit temperature sensor and is connected to the main unit via a communication line.

B. 3D-Druck) hergestellt werden.The heating and / or cooling system according to the invention and individual parts thereof can also be produced line by line or in layers using a line-building or layer-building production method (e.g. 3D printing).

In Fig. 1 ist ein Heiz- und/oder Kühlsystem 1 zur Durchführung eines Verfahrens gemäß einer Ausführungsform der vorliegenden Erfindung schematisch dargestellt. In dem Heiz-und/oder Kühlsystem 1 wird ein Temperiermedium (z.B. Wasser oder ein Wasser/Glycol-Gemisch) entlang einer Vorlaufleitung 2 mit einem Vorlauf-Temperaturfühler 3 zu einem Vorlauf-Heizkreisverteiler 4 geleitet. Der Vorlauf-Heizkreisverteiler 4 verteilt das Temperiermedium auf mehrere Heizkreise 5, 5', 5", 5'''. Die Heizkreise 5, 5', 5", 5''' führen das Temperiermedium durch die Flächen, durch die der betreffende Raum beheizt oder gekühlt werden soll.In Fig. 1 a heating and / or cooling system 1 for performing a method according to an embodiment of the present invention is shown schematically. In the heating and / or cooling system 1, a temperature control medium (for example water or a water / glycol mixture) is conducted along a flow line 2 with a flow temperature sensor 3 to a flow heating circuit distributor 4. The flow heating circuit distributor 4 distributes the temperature control medium to several heating circuits 5, 5 ', 5 ", 5"'. The heating circuits 5, 5 ', 5 ", 5"' lead the temperature control medium through the surfaces through which the room concerned should be heated or cooled.

Die Heizkreise 5, 5', 5", 5''' umfassen jeweils ein Ventil 6, 6', 6", 6''' mit einem diesem zugeordneten Stellantrieb, einen Vorlauf, einen Verbraucher (bei Fußbodenheizungen beispielsweise der Estrich des zu beheizenden oder zu kühlenden Raums, bei Heizkörpersystemen ein Heizkörper), einen Rücklauf sowie einen in der in Fig. 1 dargestellten Ausführungsform jeweils im Rücklauf angeordneten Heizkreis-Temperaturfühler 7, 7', 7", 7'''. Die Heizkreis-Temperaturfühler 7, 7', 7", 7''' können in anderen Ausführungsformen des erfindungsgemäßen Heiz- und/oder Kühlsystems 1 auch an anderen Stellen angeordnet sein, beispielsweise jeweils im Vorlauf. Auch die Anordnung an unterschiedlichen Positionen in den einzelnen Heizkreisen 5, 5', 5", 5''' ist denkbar. Die Heizkreise 5, 5', 5", 5''' münden in einem Rücklauf-Heizkreisverteiler 8. Vom Rücklauf-Heizkreisverteiler 8 fließt das Temperiermedium durch eine Rücklaufleitung 9 zurück zu einem Temperierelement 10 zur Erwärmung oder Abkühlung des Temperiermediums (z. B. eine Wärmepumpe oder eine Brennwerttherme).The heating circuits 5, 5 ', 5 ", 5"' each include a valve 6, 6 ', 6 ", 6"' with an actuator assigned to it, a flow, a consumer (for underfloor heating, for example, the screed of the or room to be cooled, for radiator systems a radiator), a return and one in the in Fig. 1 shown embodiment in each case arranged in the return heating circuit temperature sensors 7, 7 ', 7 ", 7"'. The heating circuit temperature sensors 7, 7 ', 7 ", 7"' can in other embodiments of the heating and / or cooling system according to the invention 1 can also be arranged at other points, for example in each case in advance. The arrangement at different positions in the individual heating circuits 5, 5 ', 5 ", 5''' is also conceivable. The heating circuits 5, 5 ', 5", 5''' open into a return heating circuit distributor 8. From the return flow Heating circuit distributor 8, the temperature control medium flows through a return line 9 back to a temperature control element 10 for heating or cooling the temperature control medium (e.g. a heat pump or a condensing boiler).

Die Ventile 6, 6', 6", 6''' und die diesen zugeordneten Stellantriebe sind im Rücklauf der einzelnen Heizkreise 5, 5', 5", 5''' angeordnet und steuern dort den Durchfluss des Temperiermediums durch die einzelnen Heizkreise 5, 5', 5", 5'''. Eine Regeleinheit 11 ist signalleitend mit den einzelnen Stellantrieben verbunden und steuert ihren Betrieb. Alternativ können die Ventile 6, 6', 6", 6''' und die diesen zugeordneten Stellantriebe auch dem Vorlauf der einzelnen Heizkreise 5, 5', 5", 5''' zugeordnet sein. Darüber hinaus kann das Heizund/oder Kühlsystem 1 weiter optional eine Umwälzpumpe 16 und/oder eine Verbindung 12 zwischen der Vorlaufleitung 2 und der Rücklaufleitung 9 umfassen, wobei die Verbindung 12 mit einem Mischventil 13 versehen sein kann. Die separate Umwälzpumpe 16, die Verbindung 12 zwischen der Vorlaufleitung 2 und der Rücklaufleitung 9 und/oder das Mischventil 13 sind nicht in jeder Ausführungsform des Heiz- und/oder Kühlsystem 1 zwingend notwendig.The valves 6, 6 ', 6 ", 6"' and the actuators assigned to them are arranged in the return of the individual heating circuits 5, 5 ', 5 ", 5"' and there control the flow of the temperature control medium through the individual heating circuits 5 , 5 ', 5 ", 5"'. A control unit 11 is connected to the individual actuators for signal transmission and controls their operation. Alternatively the valves 6, 6 ', 6 ", 6"' and the actuators assigned to them can also be assigned to the flow of the individual heating circuits 5, 5 ', 5 ", 5"'. In addition, the heating and / or cooling system 1 can optionally further comprise a circulating pump 16 and / or a connection 12 between the flow line 2 and the return line 9, the connection 12 being able to be provided with a mixing valve 13. The separate circulating pump 16, the connection 12 between the flow line 2 and the return line 9 and / or the mixing valve 13 are not absolutely necessary in every embodiment of the heating and / or cooling system 1.

Über den Vorlauf-Temperaturfühler 3 wird die Temperatur des Temperiermediums in der Vorlaufleitung 2 gemessen und an die Regeleinheit 11 übermittelt. Gleichermaßen misst ein der Rücklaufleitung 9 zugeordneter Rücklauf-Temperaturfühler 14 die Temperatur des Temperiermediums in der Rücklaufleitung 9 und übermittelt diese an die Regeleinheit 11. Die Regeleinheit 11 kann die Temperatur des Temperiermediums in der Vorlaufleitung 2 beispielsweise regeln, indem das Mischventil 13 entsprechend gesteuert wird. Ebenso kann ein Außentemperaturfühler 15 die Außentemperatur ermitteln und diese wiederum an die Regeleinheit 11 weitergeben.The temperature of the temperature control medium in the flow line 2 is measured via the flow temperature sensor 3 and transmitted to the control unit 11. Likewise, a return temperature sensor 14 assigned to the return line 9 measures the temperature of the temperature control medium in the return line 9 and transmits this to the control unit 11. The control unit 11 can regulate the temperature of the temperature control medium in the flow line 2, for example, by controlling the mixing valve 13 accordingly. An outside temperature sensor 15 can also determine the outside temperature and in turn pass this on to the control unit 11.

Die Verrohrung der Vorlaufleitung 2, der Heizkreise 5, 5', 5", 5''' sowie der Rücklaufleitung 9 besteht typischerweise z. B. aus Kunststoffrohren aus vernetztem Polyethylen, die mit einer Sauerstoffsperrschicht versehen sind.The piping of the flow line 2, the heating circuits 5, 5 ', 5 ", 5"' and the return line 9 typically consists, for example, of plastic pipes made of cross-linked polyethylene which are provided with an oxygen barrier layer.

Das Heiz- und/oder Kühlsystem 1 verteilt die in den einzelnen Räumen erforderliche Wärmemenge bei einer Fußbodenheizung dadurch, dass durch die Ventile 6, 6', 6", 6''' der Zufluss an Temperiermedium mit einer bestimmten Temperatur in den jeweiligen Heizkreis 5, 5', 5", 5''' im Boden geregelt/gesteuert wird. In der Regel wird ein Heizkreis 5, 5', 5", 5''' pro Raum verwendet, wobei die Wärmeversorgung eines entsprechend großen Raums auch zwei oder mehr Heizkreise 5, 5', 5", 5''' erfordern kann. Die Regeleinheit 11 sendet entsprechende Signale an die Stellantriebe der Ventile 6, 6', 6", 6''' diese für einen entsprechenden Zeitraum zu öffnen und wieder zu schließen. Man spricht von der Öffnungszeit T(open) der Ventile 6, 6', 6", 6'''.The heating and / or cooling system 1 distributes the amount of heat required in the individual rooms in the case of underfloor heating in that the flow of tempering medium at a certain temperature into the respective heating circuit 5 through the valves 6, 6 ', 6 ", 6"' , 5 ', 5 ", 5' '' in the ground is regulated / controlled. As a rule, one heating circuit 5, 5 ', 5 ", 5"' is used per room, whereby the heat supply of a correspondingly large room can also require two or more heating circuits 5, 5 ', 5 ", 5"'. The control unit 11 sends corresponding signals to the actuators of the valves 6, 6 ', 6 ", 6'" 'to open them for a corresponding period of time and to close them again. The opening time T (open) of the valves 6, 6' is referred to as the opening time T (open). , 6 ", 6 '' '.

Für die Zuordnung von einem der Heizkreis-Temperaturfühlers 7, 7', 7", 7''' des erfindungsgemäßen Heiz- und/oder Kühlsystems 1 zum zugegehörigen Heizkreis 5, 5', 5", 5''' wird zunächst das Ventil 6 des Heizkreises 5 geöffnet. Die den anderen Heizkreisen 5', 5", 5''' zugeordneten Ventile 6', 6", 6''' bleiben dabei geschlossen. Dadurch kann Temperiermedium durch den Heizkreis 5 strömen, der dem jetzt geöffneten Ventil 6 zugeordnet ist. Gelangt das neu in den Heizkreis 5 eingeströmte Temperiermedium nun im Heizkreis 5 an den entspechenden Heizkreis-Temperaturfühler 7, wird dieser die so verursachte Temperaturänderung detektieren. Diese Information wird durch den Heizkreis-Temperaturfühler 7 an die Regeleinheit 11 übermittelt und von der Regeleinheit 11 gespeichert. Dadurch wird in der Regeleinheit 11 der Heizkreis-Temperaturfühler 7 dem Heizkreis 5 zugeordnet. Anschließend kann das Verfahren entsprechend für einen der anderen Heizkreise 5', 5", 5''' durchgeführt werden, bis die Heizkreis-Temperaturfühler 7, 7', 7", 7''' aller Heizkreis 5, 5', 5", 5''' des erfindungsgemäßen Heiz- und/oder Kühlsystems 1 in der Regeleinheit zugeordnet sind.For the assignment of one of the heating circuit temperature sensors 7, 7 ', 7 ", 7"' of the heating and / or cooling system 1 according to the invention to the associated heating circuit 5, 5 ', 5 ", 5"', the valve 6 of heating circuit 5 is open. The other heating circuits 5 ', 5 ", Valves 6 ', 6 ", 6''' assigned to 5 '''remain closed. This allows the temperature control medium to flow through the heating circuit 5, which is assigned to the now open valve 6. If the temperature control medium that has newly flowed into the heating circuit 5 now enters the heating circuit 5 to the corresponding heating circuit temperature sensor 7, it will detect the temperature change caused in this way. This information is transmitted by the heating circuit temperature sensor 7 to the control unit 11 and is stored by the control unit 11. As a result, the heating circuit temperature sensor 7 in the control unit 11 becomes the Assigned to heating circuit 5. The procedure can then be carried out accordingly for one of the other heating circuits 5 ', 5 ", 5''' until the heating circuit temperature sensors 7, 7 ', 7", 7''' of all heating circuits 5, 5 ' , 5 ", 5"'of the heating and / or cooling system 1 according to the invention are assigned in the control unit.

Beispielsweise kann das erfindungsgemäße Verfahren bei der Inbetriebnahmesequenz der Regeleinheit 11 durchgeführt werden und so die Fühlerzuordnung für das erfindungsgemäße Heiz- und/oder Kühlsystem einfach und sicher erfolgen. Gleichermaßen kann im laufenden Betrieb der Anlage durch dieses Verfahren eine in der Regeleinheit 11 gespeicherte Zuordnung der Heizkreis-Temperaturfühler 7, 7', 7", 7''' auf die Kanäle der Regeleinheit 11 überprüft und im Bedarfsfall korrigiert werden. Die Positionierung der Heizkreis-Temperaturfühler 7, 7', 7", 7''' in den einzelnen Heizkreisen 5, 5', 5", 5''' ist beliebig und kann zeitlich in beliebiger Reihenfolge erfolgen.For example, the method according to the invention can be carried out during the commissioning sequence of the control unit 11 and the sensor assignment for the heating and / or cooling system according to the invention can thus be carried out simply and reliably. Likewise, during ongoing operation of the system, this method can be used to check an assignment of the heating circuit temperature sensors 7, 7 ', 7 ", 7' '' stored in the control unit 11 to the channels of the control unit 11 and correct it if necessary -Temperature sensors 7, 7 ', 7 ", 7"' in the individual heating circuits 5, 5 ', 5 ", 5' '' can be used in any order.

Während des Betriebs des erfindungsgemäßen Heiz- und/oder Kühlsystems 1 verarbeitet die Regeleinheit 11 die zu den einzelnen zu regelnden Räumen vorhandenen Informationen, also die vorgegebenen Sollwerte sowie die von Raumtemperaturfühlern gemeldeten Istwerte der Raumtemperaturen. Ein in der Regeleinheit 11 implementierter Regelungsalgorithmus erzeugt daraus ein Regelsignal, das von den Ausgängen der Regeleinheit 11 über Stellantriebe an Ventile 6, 6', 6", 6''' der Heizkreise 5, 5', 5", 5''' übermittelt wird. Hierzu wird ein an sich bekanntes Pulsweitenmodulationsverfahren eingesetzt. Dies stellt die Grundfunktion der Regeleinheit 11 dar, die an sich selbständig das Heiz- und/oder Kühlsystem 1 regeln kann. Um für eine für jeden Belastungsfall angepasste Wärmeversorgung der einzelnen Räume durch die Heizkreise 5, 5', 5", 5''' zu gewährleiten, können diese Pulsweitenmodulationsalgorithmen der Raumtemperaturregelung einer Korrektur unterzogen werden.During the operation of the heating and / or cooling system 1 according to the invention, the control unit 11 processes the information available on the individual rooms to be controlled, that is, the specified setpoints and the actual room temperature values reported by room temperature sensors. A control algorithm implemented in control unit 11 generates a control signal from this, which is transmitted from the outputs of control unit 11 via actuators to valves 6, 6 ', 6 ", 6"' of heating circuits 5, 5 ', 5 ", 5"' becomes. A pulse width modulation method known per se is used for this purpose. This represents the basic function of the control unit 11, which can independently control the heating and / or cooling system 1. In order to ensure that the individual rooms are supplied with heat by the heating circuits 5, 5 ', 5 ", 5"' for each load case, these pulse-width modulation algorithms for room temperature control can be corrected.

In bevorzugten Ausführungsformen des erfindungsgemäßen Heiz- und/oder Kühlsystems 1 ist die Regeleinheit 11 modular aus einer Haupteinheit und einer Zusatzeinheit aufgebaut. Dabei umfasst die Zusatzeinheit den Vorlauf-Temperaturfühler 3 und die Rücklauf-Temperaturfühler 7, 7', 7", 7''' und ist über eine Kommunikationsleitung mit der Haupteinheit verbunden. Dadurch wird die Nachrüstbarkeit eines Heiz- und/oder Kühlsystems 1 zur Durchführung des erfindungsgemäßen Verfahrens gewährleistet.In preferred embodiments of the heating and / or cooling system 1 according to the invention, the control unit 11 is constructed in a modular manner from a main unit and an additional unit.
