I believe it could be done, but not with standard electronics=2E

Most fan controls are looking for a contact closure, so obviously they are=

Thanks, Randall.  I really like the idea of T'ing off the heater return.  Looks like 3/8ths but don't know for sure until I break it down.  Meanwhile, when I opened the Spal fan box, I see the thermostat switch failed to make it into the packaging.  Much to late to go to the dealer.  On Amazon I see a variety of thermo fan switches 185/195, but none seem rated very well.  Could be poor wiring, I suppose. 

Any recommendations on thermo fan switches?
