CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12098-1:1996 and EN 12098-2:2001. EN 12098, Co
21、ntrols for heating systems, currently consists of the following parts: Part 1: Control equipment for hot water heating systems (the present document); Part 3: Outside temperature compensated control equipment for electrical heating systems; Part 4: Optimum start-stop control equipment for electrical
22、 systems1); Part 5: Start-stop schedulers for heating systems. This standard is for products for Outside Temperature Compensated Controls for mechanical building services and covers Outside Temperature Compensated Controls in residential and non-residential buildings. This standard is part of a seri
23、es 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 n6 Energy economy and heat retention (and its inte
24、rpretative document) and of the Energy Performance of Building Directive (2002/91/CE). This standard covers also controllers which contain an integrated optimum start or an optimum start-stop control function. According to the CEN-CENELEC Internal Regulations, the national standards organisations of
25、 the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Neth
26、erlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. 1) EN 12098-4:2005 is bound to be superseded in the future by an upcoming new edition of EN 12098-3. BS EN 12098-1:2013EN 12098-1:2013 (E) 5 Introduction Equipment which control
27、s the heating supply in buildings according to outside temperature and time is necessary to reduce the energy consumption of heating plants. This equipment can bring about improved comfort and energy savings. For this purpose, an outside temperature compensated controller (OTC) is necessary. This st
28、andard describes the main equipment characteristics and functions for reaching energy saving and comfort objectives. BS EN 12098-1:2013EN 12098-1:2013 (E) 6 1 Scope This European Standard applies to electronic control equipment for heating systems with water as the heating medium and a flow water te
29、mperature up to 120 C. This control equipment controls and regulates the distribution and/or the generation of heat in relation to the outside temperature and time and other reference variables. This standard covers also controllers which contain an integrated optimum start or an optimum start-stop
30、control function. Safety requirements on heating systems remain unaffected by this standard. The dynamic behaviour of the valves and actuators are not covered in this standard. A multi-distribution and/or multi-generation system needs a coordinated solution to prevent undesired interaction and is no
31、t part of this standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for the application of this document.
