Ok I can see what you mean that is high especially now.. what temps are you talking about exactly as being high? Is it way over 80 f let’s say if it’s getting into the mid 80’s then I totally agree, I have had same issues exactly of late, and been struggling with rh swings, however I have an unusual intake and extraction system using only large fans and ducting to the outside. I still have to use an AC sometimes to bring down temps, then use the dh to keephumidity down but if your humidity is that high I can only think that the airflow isn’t right...
