Hi my name is Robert...
The EE means there is a problem with the thermostat communicating with the board inside the AC unit, it cable be the cable or board. I would try a new cable to start. It looks like a phone cable but it is not, the ends are reversed. Below is manual for you that should have a bit of troubleshooting you can do. Also anytime you unplug the cable you must do the reset when you plug it back in. IF a new cable does not work then the circuit board is at fault...
