BAS EN 12098-4:2009

This European Standard applies to electronic equipment which controls electrical heating. In this European Standard, equipments are tested to verify conformity with technical characteristics of the materials given by the manufacturer. NOTE 1 It describes optimal start-stop heating functions. It does not include controls for storage functions and controls for lowest energy cost by controlling the charging of the heating system. The particular equipment to which this European 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; · Electrical equipment which includes this function, may includes other. NOTE 2 Electrical heating systems able to be controlled by these devices (e.g.: direct heating, mixed heating systems including base and supplement, type of emitters, type of storage heating systems, floor heating�) are indicated in the technical documents of the manufacturer. Instructions to adapt the parameters of devices to the systems to which they apply are indicated in these documents. The optimum start-stop function can be integrated within a main control device such as an outside temperature compensated (OTC) controller. In this case the controller would be expected to meet both EN 12098-3 and this document. It applies both to adaptive and fixed parameters control functions and sets minimum acceptable standards for functions, performance and documentation.
