EN 12098-3 : Energy performance of buildings - Controls for heating systems - Part 3: Control equipment for electrical heating systems - Modules M3-5,6,7,8.

This document applies to electronic control equipment for direct electric space-heating systems incorporating control based on outdoor temperature and/or an optimum start-stop function. It covers the control and regulation of heat distribution and/or generation according to outdoor temperature, time, and other reference variables, including controllers with an integrated optimum start or optimum start-stop function. The controller modulates the heating or control modes of electronic zone or emitter controllers. The safety requirements of heating systems are not affected. The dynamic behaviour of local thermostats, sensors and actuators, as well as multi-distribution and/or multi-generation systems, is not covered.
