Hi my name is Robert..
Try this... Turn the thermostat OFF, hold the top and bottom buttons down at the same time, while holding the buttons turn the thermostat back ON and you should see FF after you see that release the buttons and see if that code will go away.... The EE code is a communication fault, could be the cable or upper circuit board that is inside the AC unit .... Robert
