I bought this controller online, and installed it two days ago:

I have a fully insulated fermentation chamber lined with 2" insulation foam and sealed with Great Stuff. Also, I'm using a re-wired A/C unit that turns the fan and compressor on whenever electricity it sent through the tail.
First, I put the probe in a 2L bottle of water and set it to 63F. It turned my A/C on for for a little bit, then shut off. Few hours later, ambient temp inside was 69F and the A/C was off.
Second, I taped the probe to the outside of my fermenting bucket and shielded it from any air movement. Came home 5 hours later, A/C was off and the ambient temp was again 68F - 69F.
Third, I left the probe out in the open near the bottom of the chamber and set the temp controller to 55F. 10 minutes later I check on it, A/C is still on, and the ambient temp is 64F (I have a digital thermometer inside the chamber). I turn the temp controller dial to re-set the temp at 60F, and it turns the A/C off...even though the temp inside is still 64F, not 60F.
Does it sound like a bad temp controller, or am I just using it wrong?
