### 2.4.6. Appending data and selecting component types

After drawing the layout and placing fitting components on pipe-runs, further editing of data consists in appending information which cannot be obtained automatically from the drawings. This includes:

- lengths of pipe-runs (by default only vertical pipe-runs have their lengths taken from the drawing – these can be changed in the general data tab),

- thermal outputs of radiators heat losses in rooms, where these radiators are installed and contributions of radiators in heat losses,

- types of valves on pipe-runs or data enabling calculation of pressure drop across these valves,

- types of pipes in pipe-runs,

- connection system of each radiator with the piping, in accordance with the list from catalogues.

The last three items do not require appending data provided that default values have been specified in the general data.

Appending data in tables is also necessary when default values are not appropriate. For instance:

- ambient temperatures and pipe-run insulation,

- methods of sizing, restricting dimensions and installing radiators.

Detailed description of component data are given in further sections of this manual.

! Many data and values are derived automatically from the drawing or determined from other data. Such values are displayed in brackets. You can overwrite these values. To revert to the default value (determined automatically) enter a question mark (?) in the appropriate field and press “Enter”.

Component data are entered into the table to the right of the working screen. The contents of the table change depending on the type of component marked. To mark a component click on that component in the drawing. Correct marking (selecting) of a component is manifested by a thicker outline of the component (terminal unit is filled in with colour) and information on the types and number of marked components is displayed at the bottom of the screen in the status bar and in the header of the data table.

! Data should be appended after marking the original component.

The data is entered directly in the form of numerical values or text strings or is selected from lists. In some fields the entered value is specified after opening an auxiliary window with additional auxiliary edit fields or lists. Detailed description of field types is given in further sections of this manual.

To speed up working with the project it is advantageous to enter data for many components of the same type at the same time. There are several methods of marking multiple components:

- marking subsequent components by clicking on them while holding the Shift key,

- selecting the “Select all components of type ...” function in the “Edit” menu and specifying the required components (e.g. radiator circuit pipes),

- selecting the “Select in rectangle components of type ...” function in the “Edit” menu and specifying the required components (e.g. radiator circuit pipes) and then marking a rectangular area in the drawing.

Features that facilitate entering data are described in detail in further sections of this manual.
