I am trying to build a cold fermenting box for making beer. Building a well insulated 4 x 3 x 5 ft box and planning to use an LG portable 8000btu ac/dehumidifier unit inside the box I have laying around. I have a 2 stage temp controller that I typically use with a stand-up freezer to do this but I need more space so I'm going to build this. My thinking is if I could bypass the digital tstat and just have my temp controller turn the unit on and off as needed I could get unit to cool this box down to 35 or 40 degrees. Not sure how to wire this and what it would mean for the dehumidifier part that is integrated. Attached are picsnof the wiring diagram inside the unit, pic of digitall control wiring and the model tag. Please help.
