A solution was presented way back in post #7.
It requires two switches; one per fan and provided lockout so that the second fan cannot be operated. A single relay with a 50% duty cycle and a 30 second interval clock automated the process.

Electrically, nothing.
This is exactly what the TS asked for.
Take his Money.
But any actual improvement in Air-Comfort is highly questionable.

Ah, now I get it. :) Yes, electrically the solution can be as simple or complex as the thread starter would like. Seems in my old age I become slower on the uptake. As to creature comfort beats me. :)
