Check to see if the humidity control is turned on. If so, and the humidity setting is too low, the thermostat will overcool the house by a few degrees to reduce the humidity. So, if the thermostat is set to 80, the actual temperature will be lower. I always leave the humidity control turned off. But, I don't know if that is your problem.
