I came home to a cold house last night the screen says EE and no heat. I tried reseting it and putting in new batteries but nothing What does EE mean can't find it in my book

In spite of all my searching, I can't find anything in a Honeywell manual mentioning an EE code. In posts here & elsewhere most say the thermostat is bad. You can try calling Honeywell but I doubt you will get an answer until Monday morning. Please post back with what you find out.
