I did this conversion. Mine also runs the roof AC. Then I realized if you turn off the AC compressor but leave the fan running the humidy goes real high as fan blows all the moisture back into camper when compressor shuts off.
So now my thermo turns on and off a relay that now shuts off the AC to roof unit.
I'd be surprised if your A/C didn't have a fan input already. You shouldn't have to add a relay.
Our Eagle Cap came from the factory with a digital stat that controls both the heat and A/C. The A/C fan can be set to 'on' where it runs full time or 'auto' where it only runs with the compressor. No batteries required. It's
this one.
