IEC 60730-2-9:2026 PDF

IEC 60730-2-9:2026 applies to temperature sensing controls: - for use in, on, or in association with equipment for household appliance and similar use, including equipment for heating, air-conditioning and similar applications. The equipment can use electricity, gas, oil, solid fuel, solar thermal energy, etc., or a combination thereof. NOTE 1 Throughout this document, the word "equipment" means "appliance and equipment" and "controls" means "temperature sensing controls". - for building automation within the scope of ISO 16484 series and IEC 63044 series (HBES/BACS); EXAMPLE 1 Independently mounted temperature sensing controls, controls in smart grid systems and controls for building automation systems within the scope of ISO 16484-2. - for equipment that is used by the public, such as equipment intended to be used in shops, offices, hospitals, farms and commercial and industrial applications; EXAMPLE 2 Controls for commercial catering, heating and air-conditioning equipment. - that are smart enabled controls; EXAMPLE 3 Smart grid control, remote interfaces/control of energy-consuming equipment including computer or smart phone. - that are AC or DC powered controls with a rated voltage not exceeding 690 V AC or 600 V DC; - used in, on, or in association with equipment that use electricity, gas, oil, solid fuel, solar thermal energy, etc., or a combination thereof; - utilized as part of a control system or controls which are mechanically integral with multifunctional controls having non-electrical outputs; - using NTC or PTC thermistors and to discrete thermistors, requirements for which are contained in Annex J; - that have electrical circuits and control circuits which are, for example, operated by bimetals, magnet coils, memory metals, pressure elements, temperature-sensitive expansion elements or electronic elements. - as well as manual controls when such are electrically and/or mechanically integral with automatic controls. NOTE 2 Requirements for manually actuated mechanical switches not forming part of an automatic control are contained in IEC 61058-1-1. This document applies to - the inherent safety of automatic electrical controls, and - functional safety of temperature sensing controls and safety related systems, - controls where the performance (for example the effect of EMC phenomena) of the product can impair the overall safety and performance of the controlled system, - the operating values, operating times, and operating sequences where such are associated with equipment safety and to the testing of automatic electrical temperature sensing control devices used in, or in association with, equipment, EXAMPLE 4 Boiler thermostats, fan controls, temperature limiters and thermal cut-outs. - electrical safety of temperature sensing controls with non-electrical outputs such as refrigerant flow and gas controls, - single-operation devices as defined in this document. This document specifies the requirements for construction, operation and testing of automatic electrical controls used in, on, or in association with an equipment. This document does not - apply to automatic electrical temperature sensing controls intended exclusively for industrial process applications unless explicitly mentioned in the relevant part 2 or the equipment standard. However, this document can be applied to evaluate automatic electrical controls intended specifically for industrial applications in cases where no relevant safety standard exists. - take into account the response value of an automatic action of a control, if such a response value is dependent upon the method of mounting the control in the equipment. Where a response value is of significant purpose for the protection of the user, or surroundings, the value defined in the appropriate equipment standard or as determined by the manufacturer will apply. - address the integrity of the output signal to the network devices, such as interoperability with other d
