Electronic individual zone control equipment
Electronic individual zone control equipment
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).

EN 15500:2008 (E) 4 Foreword This document (EN 15500:2008) has been prepared by Technical Committee CEN/TC 247 “Building Automation, Controls and Building Management”, the secretariat of which is held by SNV. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2009, and conflicting national standards shall be withdrawn at the latest by January 2009. This standard is for products for electronic individual zone control equipment applications for mechanical building services and covers electronic individual zone control equipment for heating, ventilation and air conditioning applications in residential and non residential buildings. This standard is part of a series of European Standards for Control for HVAC Applications. This standard, therefore, contributes to the general European policy for energy saving, particularly in the fields of the Construction Products Directive (89/106/EEC) Essential Requirements n°6 «Energy economy and heat retention» (and its interpretative document) and of the Energy Performance of Building Directive (2002/91/CE). No existing European Standard is superseded. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

EN 15500:2008 (E) 5 Introduction Equipment to control the heating, ventilation and air-conditioning (HVAC) in a building according to the actual room or zone energy demand, is necessary in order to reduce the consumption of energy and improve the quality of the air. HVAC installations should, for the purpose of energy conservation and guaranteeing indoor environmental comfort, be equipped with automatic zone control equipment acting as function of measured inside variables in buildings. Under the term “automatic zone control equipment” is understood the functional unit comprising controller, actuator and sensor. The zone control equipment controls the comfort of the environment by controlling physical variables such as temperature, humidity, air-quality or air-flow in accordance with occupancy and user requirements. This standard, which is valid for applications in all domestic and non-domestic buildings, conforms to the requirements and objectives of the interpretative documents “Energy Economy and Heat Retention” and “Hygiene, Health and the Environment” relating to the Construction Products Directive (89/106/EEC) and the preparations for a standardisation mandate from the European Commission are on-going.
