Let me say this so that its easiest to understand for you.

The thermostat is most likely working *perfectly, considering that the **differential** was set at 0.5 degrees F at the factory, we need go into the thermostat programming and change the DIFF to 2.

See if you can find those instructions in the manual that came with the thermostat, we can go from there.
