If you wanted to do this without soldering I assume you could just connect to the blade terminal on the left. That would put the 180, 130 and variable all in series. It would also limit the hot side to 130 max which might be a good thing.
Sure, you could run it as a third Tstat in line, just means you can't go any higher than 130. In my case, I wanted hotter because the incoming cold water is so cold, it makes showers pretty short.
They make an OEM replacement of a fixed 140, you just unscrew the 180/130 tstats and put in a new set with 180/140. Runs about $26.
But I still wanted just a plain ole adjustable knob.
