Controls for heating systems. Outside temperature compensated control equipment for electrical heating systems (British Standard)
This work item applies to electronic control equipment for electrical heating systems. The signals can be processed by analogue or digital techniques. This control equipment controls and regulates the distribution and/or the generation of heat in relation to the outside temperature and/or other reference variables (e.g. room temperature, emitter temperature...) and time. Safety requirements on heating systems remain unaffected by this standard. The dynamic behaviour of the actuators is not covered here. The control equipment may or may not be connected to a data network.
