      If it is the AC-325 controller, this unit is made by Brusa (called the AMC
      325) and was distributed & used by Solectria several years back. It is still
      available from Brusa.

      You can download manuals, etc. for this controller at
      Perhaps these manuals and top-level schematics might help.
