I get a text in the SVG file saying that my Availabilitymanagers and setpoint manager are "unused non-parent objects". It happens to my own file but also in the example file I am using as reference: SolarCollectorFlatPlateWater.

What does it mean? It looks like they are working fine in the results.

The message in the SVG file about "unused non-parent objects" are informative and generally nothing to worry about. Sometimes they may be able to help with diagnostics. The algorithm used to create the SVG diagrams looks at a variety of different HVAC related objects in EnergyPlus by reading the BND file. In that file, you will see lines with "parent node connections" and "non-parent node connections". Since the non-parent node connections are used to connect the objects on the diagram, the ones that are not used are explicitly shown below the diagram to inform the user what what was not used. If your diagram does not look right and there is an unused non-parent node connection listed below, maybe something is not connected correctly in your IDF file. Most of the time, the ones listed should not be expected to be part of a diagram.

Thank you!, I understand now. According to my results I agree that there is nothing to worry about.
