The purpose of this standard is to specify the applications, functionality set and application performance for electronic individual zone control equipment. The applications are for cooling and hot water or electrical heating as described in Annex B. This standard applies specifically to individual zone control equipment for maintaining temperature, humidity and air flow as a function of occupancy and demand operated with auxiliary electrical energy. Information required for the operation of the equipment may be processed using either analogue or digital techniques or a combination of both. Safety requirements remain unaffected by this standard. This standard refers to the input and output requirements of the controller and not of the input and output devices as e. g. sensors and actuators. This standard covers fixed-function, configurable and programmable controllers. The control equipment may or may not be connected to a data-network however communications aspects are not covered by this standard. These devices could be applied for any kind of building, intermittent or non-intermittent occupation, residential or non residential (see Annex B).

This European Standard defines guidelines for the inspection of installed an operational Functions of Building Automation, Controls and Technical Building Managment System including its configuration.

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.

This document specifies requirements and test methods of valve-actuator assemblies in individual zone control of water-based HVAC applications.
Control valves of nominal diameter larger than DN50 are currently not covered by this document.
Within the scope are pressure independent and pressure dependent control valve-actuator assemblies of relevant categories: 2-port, 3-port and 6-port valves (if they incorporate a control valve function).
Where a certain control loop as a combination of controller and valve-actuator assembly was assessed under EN 15500-1:2017, this European Standard allows the assessment of the performance of combinations of that controller with different valve-actuator assemblies. The tests in this document ensure that valve/actuator assemblies, as components of control loops, can be replaced with products that provide comparable or better performance.
In hydronic system, valve-actuator assembly is a component of control loop that controls water flow rate according to the application control demand.  The common Formula (1) describing the flow rate where whole hydronic system itself has an influence on actual flow rate as differential pressure across control valve-actuator assembly typically varies during operation.
Q=k_v . √((∆p_v)/(∆p_1 bar ))
where
Q [m3/h]   water flow
kv [m3/h]   flow coefficient of the valve    
Δpv [bar]   differential pressure across the valve
Δp1bar [bar]   1 bar differential pressure
