Locking parameters
The Hysopt software calculates the optimal system parameters. However, as a designer you are always able to change parameters as you like. By clicking on the lock icon a parameter can be forced to a user defined value (the lock icon is marked in red). This way the software sees this parameter as a hard input value instead of an (optimized) calculation result. This feature is particularly useful in renovation projects where the existing parts of the system must be modeled 'as is' by locking the parameter values.
Note that parameters without lock icon are always input parameters specified by the designer, if not the presented default values are used . E.g. the minimal valve authority is not a calculation output but a user defined requirement.
Note that when several basic circuits are selected (see 'Changing parameters for multiple basic circuits'), the lock icons can be marked grey, red or orange:
- A grey marked lock icon means that the parameter value is unlocked
- A red marked lock icon indicates that the parameter value is locked for all basic circuits within the selection
- An orange marked lock icon means that the parameter value is locked for some of the basic circuits within the selection

In the example shown below, all radiators are selected at once by using the 'Alt-Click' selection. The total number of selected radiators (5) is shown at the top of the parameter box. The temperature regime 70/50/20°C and the Kv value are marked in black as the same values apply for all five radiators. The design heat flow is marked red as the selected radiators have different values for this parameter.

Using 'Shift+Alt+Click' to span multiple canvasses
The 'Shift+Alt+Click' selection is basically the same as the 'Alt+Click' selection however it spans multiple canvasses (see 'Canvas Management') whereas the 'Alt+Click' selection is restricted to the canvas which is currently shown. To make the designer aware of the fact that the 'Shift+Alt+Click' selection spans multiple canvasses, the heading of the parameter box is shown in pink.

drag selection
A drag selection can be made by dragging the mouse cursor over the desired area in the drawing canvas while pressing the left mouse button. During the drag selection movement a dashed line rectangle indicates the selected area. After the selection, the selected basic circuits are marked green and the respective basic circuits are listed in the parameter box. The respective parameter value appear when clicking on the name of the basic circuit.
