Controls for heating systems - Part 2: Optimum start-stop control equipment for hot water heating systems

Scope

This standard applies to electronic equipment which controls 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. The particular equipment to which this standard applies covers both :- stand-alone start optimisers or start-stop optimisers, taking priority to the main controller during periods.- controllers which contain an integrated optimum start or an optimum start-stop control function.It applies both to adaptive and fixed parameters control functions and sets minimum acceptable standards for functions, performance and documentation.
