If you go back thru the thread you will notice I asked you which fan you have and you stated the fan speed controller one only. I had to go to the
AC Infinity site to figure out you had the one with humidity and temperature controls. I am not sure why that happened nor do I care much. Now you are basically telling me there is not way to control both so how about this. Run the fan on 24/7 and do not use any of the temperature or humidity controls. The fan is your problem with RH in the tent. The dehu is another story. I realize you stated you make not be the sharpest tool in the shed but if you just run the fan at like 75 or 80 percent and do not use the temperature and RH features your tent will be much more happy. With your RH setting at 44 outside you should not need a dehu in the first place. Lastly, take the intake fan line and place it at the floor. How does a hot air balloon operate? Hot air raises, cold air sets on the ground. This is just basic stuff.
