can i just replace the fridge thermostat without needing an outlet box? My fridge has two thermostats. I was thinking i could just unhook the thermostat for the fridge side and wire in the ST-1000.[/quote] You can. Ive done it on mine, however the fridge is an old analog. I just found the hot and neutral, and powered the STC 1000 and attached the cold relay wires in place of the factory thermostat. Then the temperature controller tells the compressor when to kick on. As a bonus, the light works even if the compressor is off. I based mine off of Chessking's design earlier in this thread. If you got a digital fridge, and if you indeed have two thermostats then good luck. I have herd that the digital units can give you headaches, especially when the defrost cycle kicks in. Double check the two thermostats. Mine had two knobs to set the temp on both sides, but only one thermostat. the other knob manipulated a baffle between the two chambers. Also I turned mine into a fridge on both sides for holding kegs. Getting one side to maintain fermentation temps, while the other remains a freezer would be difficult at best. If you converted the freezer side to a beer fridge, and the fridge side to a ferment chamber would be easier, as the temperature variance would be reduced. there is only about an inch of insulation between the sides and I believe you would be fighting to keep the ferm chamber from getting too cool, while the freezer side would be constantly drawing the heat over and making the compressor kick in. It would be better to have your fermentation chamber as a separate unit IMHO. fortunately my wife doesn't mind me having a collection of refrigerators in the basement.
