I am not running the CHE, I originally started with 1 UTH and it wasn't enough for the cool side. So I bought a CHE and it put my humidity down to around 30%.
So I bought another UTH and put it on the thermostat that the CHE was on.

So I have 1 UTH on the warm side set to 92 and 1 UTH on the cool side set to 82 and the top of the carpet is perfect.

I have tried removing the eco-earth but the humidity falls greatly
