Attic HVAC Working!

I had a 2 zoned system upstairs with a controller that can support 4.  So I tapped into the existing system and added a 3rd zone.

First I added the new trunk with a damper.

And tapped into the air return:

And set the distribution box above the room with 6 lines coming out of it (2 on each side).  Tested and everything works perfect!
