Does this diagram show the manifold?

No. It shows the supply and return points at each room's doorway. Add the manifold and its run to each loop in ArcSite.

Can I change the tubing spacing?

Yes! Tighten or widen the loop spacing in ArcSite to fit each room's heat loss.

Can my office see the layout before I get back?

Yes. Sync means office staff can open your layout while you're still parked in the driveway.
