Abstract
This European Standard applies to electronic control equipment for heating systems with water as the heating medium and a flow temperature up to 120 °C. The signals can be processed by using either analogue or digital techniques, or both. This control equipment controls and regulates the distribution and/or the generation of heat in relation to the outside temperature and other reference variables and time. Safety requirements on heating systems remain unaffected by this standard. The dynamic behaviour of the valves and actuators are not covered in this standard.
