I have a RiteTemp thermastat. I don't know what the model number is. It doesn't say on it. I am trying to figure out what the blinking picture is but it is too small for me to see it. It is almost like the 8030 model except the Reset, Menu, and Program button is on the right side. My AC is not working. I cannot put the temperature down or up because the thermastat is not allowing me to do so. I tried resetting and turning it off and still not able to do anything. How do I know what the model number is so I can figure out what the blinking picture is on the bottom.
