Yesterday I finished building my STC-1000 Temp controller for my fermentation chamber, and I've had it running now for about 24 hrs. I used a Lasko My Heater 200 W ceramic space heater for the heat source, and am wondering if 200W is too high for my little 7 cf freezer. I don't have anything actively fermenting, just a porter conditioning, but the cycling seems fairly dramatic. I have my temp sensor in water right now (not trying to control a fermentation), and the overshoot is more than I was expecting. It seems reasonable to me that a smaller heat source (60 W bulb-in-paint-can or something) would heat more slowly, and the water temp would be able to follow the chamber temp more closely.
Has anyone else had a similar issue? I realize this will be completely different during fermentation, but would like to be able to control temps well throughout the process. Suggestions?
