EN 12098-1:2013

This European Standard applies to electronic control equipment for heating systems with water as the heating medium and a flow water temperature up to 120 °C.This control equipment controls and regulates the distribution and/or the generation of heat in relation to the outside temperature and time and other reference variables.This standard covers also controllers which contain an integrated optimum start or an optimum start-stop control function.Safety requirements on heating systems remain unaffected by this standard. The dynamic behaviour of the valves and actuators are not covered in this standard.A multi-distribution and/or multi-generation system needs a coordinated solution to prevent undesired interaction and is not part of this standard.
