I'll start off by saying this is not a how do I wire the STC 1000 thread. I've already wired the controller and am pretty certain I wired it correctly but it keeps cooling my refrigerator well past the point I set it to cool to. I have F1 set at 16.6C but the controller keeps the fridge on even when the sensor is reading 15.2C. F2 is set to 1C. I have the STC 1000 wired to a duplex outlet so the first thing I did was switch the plug from the 1st spot to the 2nd spot on the power outlet to make sure I didn't accidentally plug it into the heating spot. However, the fridge turns on at 15.2C when it is plugged into either spot when my set temp is 16.6C. This makes me think maybe the wiring is messed up so here is what I did

Blue Circle indicates this is where I connected the wires together using your standard screw on wire connector
