## 3.5. Catalogue selection

Catalogues for Instal-therm constitute files prepared by the software producer with data on the components which make up the installation. The user cannot create his or her own catalogues, neither can he or she modify existing catalogues. Moreover, various versions of the software (e.g. complete version and version dedicated to pipe manufacturer) have different levels of authority to read individual catalogues.

Each project has a defined set of catalogues, which are used during system editing and calculations. Of course it is possible to use all available catalogues in a project. Then, however, you will sometimes have to go through long lists of available types. Calculations cannot be done without at least declaring a default pipe catalogue. Usually every project also requires a catalogue of miscellaneous fittings (without specifying manufacturer) with generally available components.

¨ To be able to specify catalogues to be used in the project select “Options / Catalogues” () or click on the “Catalogues” button in the general data window.

A window with two lists is displayed: the list on the left side contains all available catalogues, whereas the list on the right shows catalogues selected for the project. Tabs at the top of the window are used to switch between different catalogues used in the project.

Catalogues can be moved from one list to the other. For this purpose arrow buttons located between the lists are used. The single arrow button moves marked catalogues only, while the double arrow button moves all catalogues.

A symbol can appear in both lists beside a catalogue name. It indicates that the catalogue includes graphical information. This information can be displayed by pressing F1 and Shift+F1 keys when selecting a catalogue or a component from that catalogue.

The list of catalogues used in the project can also include the following symbols: “Z”, “U!” and “U”. They have the following meanings:

- Z – catalogue always loaded from disc (read into every project),

- U! – catalogue already used in current sheet (at least in one component),

- U - catalogue used in other sheet of the project.

! Catalogues marked with “U!” or “U” cannot be removed from the list.
