Paul,
   TRNBuild/Type56 will allow you to set the boundary temperature either 
as a "identical" or as a constant, an input, or a schedule. You want to 
select "userdefined" then click on the little arrow button to the left 
of the constant boundary temperature that pops up. Change from 
"constant" to "input." Go back to the Simulation Studio, right click on 
Type56 and tell it to update the input list. Once it does, you should 
see your the boundary temperature as an input. Read in your measured 
boundary temperature using type9 and pass the appropriate output to Type56.
Best,
  david
