The system has one temp but the heater temp should be turned all the way up outside on the unit as well

I had the same problem and a friend of mine told me that the board is shot and needs to be replaced. I got a new board and installed it just now and everything is working fine now. The back of the board looked a little fried. If you can take the board out which is connected by a ribbon cord and plug and 4 screws on front. It might be possibly fixed by an electronic person or else you will have to get a whole new board $275. Sorry
