Benjamin,
  It is not clear from your email which example you are starting from or 
which diverting valve component you are referring to. If you are 
referring to the example in ..\Trnsys17\Examples\ then I would suggest 
that you look at the documentation for Type11 whose algorithms are 
explained in the Type11 section of the 04-MathematicalReference. If you 
are speaking of a different example or if you are trying to use the 
tempering valve controller in the TESS Controls library (Type953) then 
again I would refer you to the documentation of that component. It can 
be found in ..\Trnsys17\Tess 
Models\Documentation\02-ControlsLibraryMathematicalReference.pdf
