Upgrading my thermostat, currently I have a "Robertshaw 9520". I just bought a honeywell RTH7000. Having some trouble on the wireing any help would be great, thanks.

Honeywell spells it all out for you here.

In your picture it is all laid out for you. Just label each wire before removal and put it back on the same letter. O to O G to G etc.

Make sure you go into the system setup on the thermostat because you will have to make settings for your type of system after the wiring is done.

Now if you cannot tell how the wiring diagrams work I would suggest you call for PROFESSIONAL ON SITE SERVICE.
