The Coolbot is working, hurrah. It turns out to be the little miracle device I had thought it would be.
When I first installed the unit, I had misinterpreted the instructions. But with the generous help of the inventor/maker/seller, we finally got it to work right. It has been running the air conditioner for a week now and it works great. It keeps the room at the desired temperature and the humidity level stays at about 95%. This is much better than before. It already cut down the mites population, so the cheeses are save and I don't have to move them upstate.
