Any thermostat will work better/accurate if you keep any outside influences away. I stuffed insulation in the hole then put some tape over that as I installed it.
Another thing is the location. One of mine is near the main door so every time someone opens it, it is so precise that it will react.
Also be aware where your cold vents are pointed. A ceiling vent blowing towards the thermostat can cause it to appear inaccurate.
