I'm trying to create some systems and I'm having problems with one of my RTUs. I added my diffusers to a system, then added my VAV as the equipment, then added several VAVs to a system but when I try to select the RTU for the equipment it won't allow it. It will allow me to add the RTU to the systemas a child but not as the parent. I also see that the RTU is in the Default Air Supply user name) system and I can't remove it. I've tried putting in a new RTU but it places that in the Default system as well and I can't make it the parent of a system.

There are several RTUs in my model that are working with other VAV systems but I can't figure out why this one is being so difficult. I can probably come up with a work around but I'd like to figure this out and make adjustments to my family, but I'm not seeing any differences between them right now.

Also, why can't System Names be organized by the name of the Parent system instead of the Type of the Parent? Makes it difficult to track down the system in the browser if you have 15 of the same type RTUs.

Is this one of those things that was fixed in the 2012 release? I hope so.

I found my issue for the RTU; the Supply and Return connections were reversed. The Supply Flow Direction was set to In. That's fixed.
