Hunter thermostsat conversion problem
I decided to do the Hunter 42999B conversion on my TT as the Duo-Therm thermostat was like all the others. I have a Dometic Duo-Therm 13,500 roof air, and I THINK an Attwood furnace (if need be I can...

Update on my conversion:
Chris was correct - I had to have BOTH the blue & orange wires (fan wires) on G to make the cooling fan come on..... I haven't added the switch, as my dealer in Texas said the low speed would sometimes allow a freeze-up to occur.
I totally missed the switch wiring showing the switch adds the 2nd wire to the circuit.
Additionally I believe the pins were not making contact between the thermostat & mounting base properly - I remounted the base as I had an over-sized hole for one screw. After The solid mount it clicked together like it should have.
The only thing is that the A/C fan (not compressor) turns on when the heat is on (furnace fan also works then). But I guess it just circulates the heat better as there is no cooling, just air movement.
This mod keeps the A/C w/in 1 degree, and also seems to start the compressor better (no more short cycling and buzzing, just instant starts).
Thanks for the help!
