Temperature control devices and temperature limiters for heat generating systems
1.1 This European Standard applies to electrical or non electrical temperature control devices which are used to control temperatures within heat generating systems by controlling the supply of energy. It also applies to limiting devices which ensure that the temperature in heat generating systems will not exceed a predefined limit.
This European Standard specifies operating values, operating times, and operational sequences associated with the safety of the heat generating system.
This European Standard also applies to controls using NTCs or PTCs thermistors, additional requirements for which are contained in Annex J of EN 60730-2-9:2010.
This European Standard applies to controls with a rated voltage not exceeding 690 V and with a rated current not exceeding 63 A.
This European Standard also applies to manual controls if, electrically and/or mechanically, they form an integral part of automatic controls.
NOTE Requirements for manually operated switches not forming part of an automatic control are contained in EN 61058 1.
This European Standard does not apply to room thermostats.
1.2 This European Standard does not take into account the response value of an automatic action of the control, if such a response value is dependent upon the method of mounting the control in the heat generating system or equipment, in which case the control should be tested together with the heat generator. Where a response value is of significance for the protection of the user or surroundings, the value defined in the appropriate household equipment standard or as determined by the manufacturer applies.
1.3 This European Standard applies also to controls incorporating electronic devices, requirements for which are contained in Annex DX.
Temperaturregeleinrichtungen und Temperaturbegrenzer für wärmeerzeugende Anlagen
1.1 Diese Europäische Norm gilt für elektrische oder nichtelektrische Temperatur¬regeleinrichtungen, die zur Regelung der Temperatur in wärmeerzeugenden Anlagen durch Regelung der Energiezufuhr verwendet werden. Sie gilt ebenfalls für Begrenzungseinrichtungen, die sicherstellen, dass die Tempera¬tur in den wärme-erzeugenden Anlagen eine zuvor festgelegte Grenze nicht überschreitet.
Diese Europäische Norm legt Betriebswerte, Betriebsdauer und Betriebsabläufe fest, die von der Sicherheit der wärmeerzeugenden Anlage vorgegeben werden.
Diese Europäische Norm gilt auch für Regel und Steuergeräte, in denen NTC oder PTC Thermistoren verwendet werden, für die zusätzlichen Anforderungen nach EN 60730 2 9:2010 Anhang J, enthalten sind.
Diese Europäische Norm gilt für Regel und Steuergeräte mit einer Bemessungsspannung bis zu 690 V und einem Bemessungsstrom bis zu 63 A.
Diese Europäische Norm gilt auch für manuell betätigte Regel und Steuergeräte, falls diese elektrisch und/oder mecha¬nisch einen integralen Bestandteil von automatischen Regel und Steuergeräten darstellen.
ANMERKUNG Anforderungen an manuell betätigte Schalter, die nicht zu einem automatischen Regel und Steuergerät gehören, sind in EN 61058 1 enthalten.
Diese Europäische Norm gilt nicht für Raumtemperaturregler.
1.2 In dieser Europäischen Norm wird der Ansprechwert einer automatischen Wirkungsweise des RS nicht berücksichtigt, wenn ein derartiger Ansprechwert von der Art des Anbringens des RS in der wärmeer-zeugenden Anlage oder dem Betriebsmittel abhängt; in diesem Fall sollte das RS zusammen mit dem Wärmeerzeuger geprüft werden. Ist ein Ansprechwert von besonderer Bedeutung für den Schutz des Benutzers oder der Umgebung, gilt der in der entsprechenden Haushaltgerätenorm definierte oder der vom Hersteller bestimmte Wert.
1.3 Diese Europäische Norm gilt auch für RS, die elektronische Einrichtungen enthalten und für die die Anforderungen in Anhang DX enthalten sind.
Dispositifs de régulation et de limitation de température pour les systèmes générateurs de chaleur
1.1 La présente Norme européenne s’applique aux dispositifs de régulation de la température d’appareils électriques ou non électriques, utilisés pour contrôler la température dans des systèmes générateurs de chaleur en agissant sur l’alimentation en énergie. Elle s’applique également aux limiteurs qui permettent de maintenir la température dans les systèmes générateurs de chaleur à une valeur ne dépassant pas une limite prédéfinie.
La présente Norme européenne spécifie des valeurs de réglage, des durées de fonctionnement et des séquences de fonctionnement associées à la sécurité du système générateur de chaleur.

La présente Norme européenne ne s’applique pas aux thermostats d’ambiance.
1.2 La présente Norme européenne ne prend pas en considération la valeur de réponse d’une action automatique du dispositif de commande lorsqu’elle est influencée par la méthode de montage du dispositif de commande dans le système ou l’équipement générateur de chaleur, auquel cas il convient de soumettre à l’essai le dispositif de commande avec le générateur de chaleur. Dans le cas où une telle valeur de réponse est importante du point de vue de la protection de l’utilisateur ou de l’environnement, la valeur spécifiée dans la norme relative à l’équipement domestique approprié ou prescrite par le fabricant s’applique.
1.3 La présente Norme européenne s’applique également aux dispositifs de commande incorporant des dispositifs électroniques, pour lesquels des exigences sont mentionnées en Annexe DX.

c) This property shall be declared by the manufacturer (see Table BX.1, requirement 206). 14.204 Sensing elements of temperature sensing controls for heat generating systems of type 1 action or type 2 action shall be capable of withstanding for one hour temperatures 15 % or 25 K above the maximum setting temperature, whichever is the highest value, unless the manufacturer declares a different value in Table 7.2, requirement 218 of EN 60730-2-9:2010. In this case, the declared value applies. After the test, the temperature sensing elements shall continue to operate in the intended manner. For controls of type TB, STW, ATW, Th, STB, ASW, and ASTB which are intended to keep the temperature below a certain limit, the operating temperature shall not have changed by more than ±2 K after the test.
