EN 15500-1:2017

• Abstract:

  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).

Overview

EN 15500-1:2017 - published by CEN - is part of the EPB (Energy Performance of Buildings) set of standards and defines requirements for electronic individual zone control equipment (Modules M3-5, M4-5, M5-5). The standard covers electronic zone controllers used for maintaining temperature, humidity and airflow in response to occupancy and demand. It applies to cooling and to hot‑water or electrical heating systems and addresses fixed‑function, configurable and programmable controllers. EN 15500-1:2017 refers to controller input/output requirements (not to sensors or actuators) and excludes communications protocol details and safety requirements (which remain unaffected).

Key Topics

• Scope of application: individual zone control for residential and non‑residential buildings, intermittent or continuous occupation.
• Functional requirements: minimum operating modes including economy and frost/building protection, and controller functions for temperature, humidity and airflow control.
• Control performance: definitions and test methods for control accuracy (e.g., CA, CV, CSD are defined within the document) and procedures for verifying compliance.
• Hardware and interfaces: inputs and outputs required of the controller, power supply and data protection considerations, user interface (UI) requirements.
• Electrical and environmental tests: supply voltage, EMC, degree of protection, and temperature stress tests.
• Documentation and marking: installation instructions, user operating instructions and product marking required for compliant devices.
• Applicability: supports application performance for cooling, hot‑water and electrical heating systems (see Annex B for application examples).

Applications

EN 15500-1:2017 is practical for the design, manufacture, selection and verification of electronic zone controllers in HVAC systems:

• Manufacturers: to design controllers that meet EPB application and performance criteria.
• System integrators and installers: to select compliant controllers and follow required installation/commissioning information.
• HVAC designers and engineers: to specify controllers for zoned heating, cooling and ventilation systems.
• Energy managers and certifiers: to assess building control performance as part of energy performance evaluations.
• Regulators and procurement: to reference harmonized functional and testing requirements in tenders and compliance checks.

Who should use this standard

Manufacturers, building automation professionals, HVAC consultants, facility managers, product test laboratories and authorities involved in implementing energy performance regulations and building certification.
