This document is applicable to electronic control equipment for heating systems with direct electrical emission, which have an integrated outside compensated function and or optimum start/stop function. 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 is also applicable to controllers that contain 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 document. The dynamic behaviour of the local thermostats, sensors, or actuators is 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.
