31、driven compressor, is fit for the use designated by the manufacturer, when used for space heating or for hot sanitary water. When these units are used for space cooling, EN 814-3 applies; when these units are used for liquid cooling and heat recovery, EN 12055 applies. This standard also specifies r
32、ecommendations for the way the characteristics of units shall be specified by the manufacturer in order to assist users and manufacturers in the understanding and comparison of various types. This standard applies to factory-made units which can be ducted. In the case of units consisting of several
33、parts, the standard applies only to those designed and supplied as a complete package. Units having two or more indoor sections connected to a single outdoor unit (multiple split system air conditioners or heat pumps) are excluded from this standard. This standard does not apply to continuously vari
34、able capacity control units. Installations used in industrial processes are not within the scope of this standard. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate pla
35、ces in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

This means that the sanitary water is heated from the lower limit of use until the upper limit of use (switching off the unit by the hot water thermosta

The ambient conditions during the test shall be as specified in tables 2 and 3 of EN 255-3 : 1997.
