@MingboPeng…lots of questions today…thanks for your help as always!

what connections would I need to do in order to do a Primary/Secondary Chilled Water Loop? I tried connecting a CW Loop to the “Supply” node of another CW Loop but got an error. Any insight would be great! thanks!

You will need a “Fluid Heat Exchanger” to connect first loop’s supply side to the second loops’ demand side. Something like this?

Right, both loops need to be connected to HVACSystem
