UNE-EN 12098-1:2023

This document applies to electronic control equipment for heating systems with water as the heating medium and a supply water temperature up to 120 °C.This control equipment controls the distribution and/or the generation of heat in relation to the outside temperature and time and other reference variables.This document covers also controllers that contain an integrated optimum start or an optimum start-stop control function.Safety requirements on heating systems remain unaffected by this document.The dynamic behaviour of the valves and actuators are not covered in this document.A multi-distribution and/or multi-generation system needs a coordinated solution to prevent undesired interaction and is not part of this document.Table 1 shows the relative position of this document within the set of EPB standards in the context of the modular structure as set out in EN ISO 52000-1.NOTE 1 In CEN ISO/TR 52000-2 the same table can be found, with, for each module, the numbers of the relevant EPB standards and accompanying Technical Reports that are published or in preparation.NOTE 2 The modules represent EPB standards, although one EPB standard can cover more than one module and one module can be covered by more than one EPB standard, for instance a simplified and a detailed method, respectively.
