I used my T4 in my dry tent, and it did kick on when set right. Only kicked on when humidity went over 64%it would bring it back down to 58 and cut off.. then back on when needed. I smoke way too much to break it down since I set it quite a while ago. Hence why I haven't been able to revert the settings back to where I need it for the grow
lol You can set it like 6 different ways tho, and swap settings when you need to...but each setting has to be fully set up for them to work properly. Still don't have it all down myself, but wanted you to know it's possible. Until I get those settings on smash I'll just manually change it.
