I wish i had the knowledge to write code but I don't.... yet. I am a programming luddite so it is really hard for me.

BBP, could you write one with 1 thermister instead of the pressure sensor and the thermister? If you want to replicate a standard TXV, one would be enough, no?

I looked on the Fujitsu circuit diagrams and do not see a pressure sensor anywhere, just numerous thermisters. As they are just plug in to the board, I don't know if one or two (or three) are used to control the EEV
