This document applies to electronic control equipment for heating systems with direct electrical emission, which have an integrated outside compensated function and or optimum start/stop function.
This control equipment controls the distribution and/or the generation of heat in relation to the outside temperature and time and other reference variables.
This document also covers controllers that contain an integrated optimum start or an optimum start-stop control function. The controller modulates heating or control modes of electronic individual zone or emitter control equipment.

Safety requirements on heating systems remain unaffected by this document. The dynamic behaviour of the local thermostats, sensors, or actuators is not covered in this document.
A multi-distribution and/or multi-generation system needs a coordinated solution to prevent undesired interaction and is not part of this document.
Table 1 shows the relative position of this document within the set of EPB standards in the context of the modular structure as set out in EN ISO 52000-1.
NOTE 1 In CEN ISO/TR 52000-2 the same table can be found, with, for each module, the numbers of the relevant EPB standards and accompanying technical reports that are published or in preparation.
NOTE 2 The modules represent EPB standards, although one EPB standard can cover more than one module and one module can be covered by more than one EPB standard, for instance a simplified and a detailed method, respectively.

This document specifies calculations for the dimensioning of Kachelgrundöfen/Putzgrundöfen (tiled/mortared stoves) based upon the required nominal heat output of the stove as declared by the producer. The Kachelgrundöfen/Putzgrundöfen (tiled/mortared stoves) are of individual one-off construction design. The document can be used for log wood fired Kachelöfen (tiled stoves) that burn one fuel load per storage period with a maximum load between 10 kg and 40 kg (log wood with water content from 12 % to 20 %, thickness of 5 cm to 10 cm in diameter, length varies usually from 25 cm to 50 cm, and is oriented toward the combustion chamber dimensions) and a storage period (nominal heating time) between 8 h and 24 h.
This document is valid for Kachelgrundöfen/Putzgrundöfen (tiled/mortared stoves) equipped with fireclay as interior material, with an apparent density between 1,750 kg/m3 and 2,300 kg/m3, a degree of porosity from 17 % up to 33 % by volume and a heat conductivity from 0,90 W/mK up to 1,30 W/mK (temperature range 20 °C to 400 °C).
This document is valid for Kachelgrundöfen/Putzgrundöfen (tiled/mortared stoves) with combustion air supply from the side via a heating door frame or the standing grate of the heating door into the combustion chamber. The document is valid for an inflow speed of the combustion air between 2 m/s and 4 m/s.
This document also applies to the combination with combustion chambers that are suitable for one-off Kachelgrundöfen/Putzgrundöfen (tiled/mortared stoves) and for which compliance with the legally required emission values has been verified as part of a type test by an accredited and/or notified body.
This document is applicable to combustion chambers:
• with an air-fuel ratio of between 1,95 and 3,95 according to the type test;
• with a maximum fuel less than 10 kg, but more than 5 kg;
• using other suitable materials as well as fireclay.
With regard to the type test, this document is applicable combustion chambers which are:
• from slow heat release appliances tested according to EN 15250 (or prEN 16510-2-5);
• inserts tested according to EN 13229 (or prEN 16510-2-2); or
• combustion chambers tested according to respective national standards (e.g. ÖNORM B 8303).
This document applies to type tested combustion chambers designed for batch fired pellet burning if meeting the requirements according to this document (air-fuel ratio between 1.95 and 3,95, the load of the pellets shall be burned in 78 ± 20 min).
This document is not valid for combinations with water heat exchangers for central heating or other heat absorbing elements like open water tanks and glass plates greater than 1/5 of the combustion chamber surface, etc. This document is not valid for mass-produced prefabricated stoves (slow heat release appliances) or partly prefabricated stoves (slow heat release appliances) according to EN 15250.
