In the section Radiant Heating and Cooling, you can define the labels for radiant heating and cooling circuits and manifolds. The labeling blocks in *.DWG format are taken from the following program directory:
..\ProgramData\LINEAR GmbH\Solutions xx\Building\Flaechentemperierung\User-Standards\Labels\DE.
You can open and edit the label with a CAD program. If, for example, you would like to change the arrangement of the label or hide a certain specification, change the label block and save it under a different name so that the original file is retained.
