This clause of Part 1 is replaced by the following:
This document applies to automatic electrical air flow, water flow and water level sensing controls
• for use in, on, or in association with boilers with a maximum pressure rating of 2 000 kPA (20 bar) and equipment for general household and similar use including controls for heating, air-conditioning and similar applications;
NOTE 1 Throughout this document, the word "equipment" means "appliance and equipment" and „controls“ means „automatic electrical air flow, water flow and water level sensing controls“.
EXAMPLE 1 Water flow and water level sensing controls of the float or electrode-sensor type used in boiler applications and air flow, water flow and water level sensing controls for swimming pool pumps, water tank pumps, cooling towers, dishwashers, washing machines, air conditioning chillers and ventilation applications.
• for building automation within the scope of ISO 16484 series and IEC 63044 series (HBES/BACS);
EXAMPLE 2 Independently mounted air flow, water flow and water level sensing 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 3 Controls for commercial boilers, heating and air-conditioning equipment.
• that are smart enabled controls;
EXAMPLE 4 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 where the DC source is provided by primary or secondary batteries;
• 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 are mechanically or electrically operated, responsive to or controlling air flow, water flow and water level;
• 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.
