Temperaturregler- och temperaturbegränsningsutrustningar för värmeproduktionssystem
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 requires 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.
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.
