I figured it out....what was confusing me was the 24v and the com wire into the switching relay as shown on the tek pic.    What I needed to do was C to Com(which was labeled as 24vav/com on the taco switching relay) R to Rh, W to W1,  and put a jumper from R to Rh in the t-stat.

Initially I wanted the slab to be set at 55, but 65 is much nicer  :) but we shall see about the consumption.
