Since FR built the unit they certainly have the diagrams. As I said in my previous post, I got mine thru my dealer. The plumbing diagrams I got from FR through customer service but your dealer probably could get them as well.
However your unit may or may not be built exactly like the diagrams. I found an example where the installation didn't match. It was a relatively easy fix and FR offered to correct but I did it my self. Bottom line you may just have to trace out the wiring to be sure whether it can be used for what you want. To add the pump switch you will have add at least one more wire anyway or two more wires (3 way setup) if you want the pump to be controlled from two places.
