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 I 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.
Additional functions, e.g.:
- adaptive functions,
- tariff compensated function, for cost optimisation applicable for more complex tariffs, including more than two
levels,
- function taking account other measures and other parameters introduced supplementary parameters
should be able to be the object of requirements and test method as complement to this European Standard.
Safety systems and heating control systems remain unaffected by this European Standard. The actuators are not
covered in this European Standard.
This European Standard does not cover heat emitters.
This control equipment can be connected to a data network.
Input and output signal can be processed by analogue or digital techniques.
