18、supersedes EN 12098-3:2002 and EN 12098-4:2005. The following modifications have been made: update of the state of the art of the platform used for the controllers (between first edition still analogical technology to day full DDC with C); test specification has been revised and described more preci

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 stan

20、dard 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 n6 “Energy economy and heat

21、retention“ (and its interpretative document) and of the Energy Performance of Building Directive (2002/91/CE).

24、nited Kingdom. BS EN 12098-3:2013EN 12098-3:2013 (E) 4 Introduction Equipment which controls the heating supply in buildings according to outside temperature and time is necessary for the reduction of the energy consumption of heating plants. This equipment can bring about improved comfort and energ

25、y savings. For this purpose, an outside temperature compensated function like that provided by an outside temperature compensated (OTC) controller is necessary. This standard describes the main equipment characteristics and functions for reaching energy saving and comfort objectives. This standard c

26、overs also controllers which contain an integrated optimum start or an optimum start-stop control function. BS EN 12098-3:2013EN 12098-3:2013 (E) 5 1 Scope This European Standard applies to electronic control equipment for heating systems with direct electrical emission, which do not have an integra

27、ted outdoor compensated function and or optimum start/stop function. 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 European Standard also covers controllers which contai

28、n an integrated optimum start or an optimum start-stop control function. The controller modulates heating or control modes of electronic individual zone or emitter control equipment. Safety requirements on heating systems remain unaffected by this standard. The dynamic behaviour of the local thermos

29、tats, sensors, or actuators is not covered in this standard. A multi-distribution and/or multi-generation system needs a coordinated solution to prevent undesired interaction and is not part of this standard. 2 Normative references The following documents, in whole or in part, are normatively refere
