Bobby_M said:The problem is you probably have your controller's sensor in the air or in some water. The beer itself is generating heat as it ferments. Your controller has no idea this is happening. You have two options;
1. Get a thermowell so you can put your sensor IN the beer.
2. Tape the sensor to the side of the fermenter (second best but better than nothing).

i want to ferment the liquid at 70 degrees consistant
i havent been able to do that yet
if i put the sensor in the liquid the fridge will run to -20 degrees + that is not what i want to happen.
still tinkering

I think roofman is right. If you have 5gal of beer at 70df, and the temp probe is in a thermowell, and the tyhermostat is set to cool until 68df, then the controller will run the fridge full steam until the beer is down to 68df. At which point the rest of the interior of the fridge will be really cold. This could cause you to undershoot the temperature, as well as waste a lot of electricity.
