I have the following colored wires coming out of the wall
Green
Red
Orange
Yellow
White
Black
Blue

The thermostat has the following connections:
G
RC
RH
Y/O
W/B
Y1

I can't get the thermostat to run. Please tell me where to attach the different colored wires.

Did you not tag the colored wires as you removed them from the old tstat? That makes it really hard /maybe impossible, you could go to the furnace and find out what each color wire is going to

Even then you will be luck if a Hunter tstat works,, most are Junk
