Energy performance of buildings - Controls for heating systems - Part 1: Control equipment for hot water heating systems - Modules M3-5, 6, 7, 8

This document is applicable 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 also is also applicable to 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.

Engergieeffizienz von Gebäuden - Mess-, Steuer- und Regeleinrichtungen für Heizungen - Teil 1: Regeleinrichtungen für Warmwasserheizungen - Module M3-5, 6, 7, 8

Dieses Dokument gilt für elektronische Regeleinrichtungen für Heizungsanlagen mit Wasser als Wärme-träger und einer Vorlauftemperatur bis 120 °C.
Diese Regeleinrichtungen dienen der Steuerung der Wärmeverteilung und/oder  erzeugung in Abhängigkeit von der Außentemperatur, der Zeit und anderen Führungsgrößen.
Dieses Dokument behandelt auch Regeleinrichtungen mit integrierter Einschalt-Optimierungsfunktion oder Ein-/Ausschalt-Optimierungsfunktion.
Sicherheitstechnische Anforderungen an Heizungsanlagen bleiben von diesem Dokument unberührt.
Das dynamische Verhalten von Ventilen und Stellgliedern wird in diesem Dokument nicht behandelt.
Eine Anlage mit mehreren Verteilkreisen und/oder Erzeugern erfordert eine koordinierte Lösung, um unerwünschte Wechselwirkungen zu vermeiden, und ist nicht Gegenstand dieses Dokuments.

Performance énergétique des bâtiments - Régulation pour les systèmes de chauffage - Partie 1 : Equipement de régulation pour les systèmes de chauffage à eau chaude - Modules M3-5, 6, 7, 8

Le présent document s’applique aux dispositifs électroniques de régulation pour les systèmes de chauffage qui utilisent l’eau comme fluide caloporteur, avec une température de l’eau allant jusqu’à 120 °C.
Ces dispositifs de régulation servent à la commande et à la régulation de la distribution et/ou de la production de chaleur en fonction de la température extérieure et du temps, ainsi que d’autres variables de référence.
Le présent document couvre également les régulateurs contenant une fonction intégrée de commande de démarrage optimisé ou de démarrage-arrêt optimisé.
Les exigences de sécurité relatives aux systèmes de chauffage ne sont pas affectées par le présent document.
Le comportement dynamique des vannes et des actionneurs n’est pas couvert par le présent document.
Un système multidistribution et/ou multiproduction nécessite une solution coordonnée pour empêcher toute interaction indésirable, mais un tel système ne relève pas du domaine d’application du présent document.

Energijske lastnosti stavb - Naprave za regulacijo sistemov za ogrevanje - 1. del: Naprave za regulacijo toplovodnih sistemov za ogrevanje - Moduli M3-5, 6, 7, 8

Ta evropski standard se uporablja za elektronske naprave za regulacijo sistemov za ogrevanje, pri katerih je grelni medij voda, ki dosega temperaturo do 120 °C.
Te naprave za regulacijo nadzirajo razporeditev in/ali proizvodnjo toplote glede na zunanjo temperaturo in čas ter druge referenčne spremenljivke.
Ta standard zajema tudi krmilnike z vgrajeno nadzorno funkcijo za optimalni zagon ali optimalni zagon/ustavitev.
Ta standard ne vpliva na varnostne zahteve za sisteme za ogrevanje.
Dinamično obnašanje ventilov in sprožilnikov ni zajeto v tem standardu.
Večdistribucijski in/ali večproizvodni sistem potrebuje usklajeno rešitev, da se preprečijo neželeni medsebojni vplivi, in ni del tega standarda.
Preglednica 1 prikazuje relativno mesto tega standarda znotraj skupine standardov EPB v kontekstu modularne strukture, kot je opredeljeno v standardu EN ISO 52000-1.
OPOMBA 1:   V standardu CEN ISO/TR 52000-2 je za vsak modul mogoče najti enako preglednico s številkami ustreznih standardov EPB in spremnimi tehničnimi poročili, ki so objavljeni ali v pripravi.
OPOMBA 2:   Moduli predstavljajo standarde EPB, čeprav lahko en standard EPB zajema več kot en modul, en modul pa je lahko zajet v več kot enem standardu EPB (na primer poenostavljena metoda in podrobna metoda).
