[RFI] Another look at Geothermal H&V

[K8RI]

I attended a seminar on GeoThermal H&V yesterday pushing the Trane 
units. They use a variable speed fan that sounds like it may be 
controlled by pulse width modulation.

I asked if they would guarantee no RFI and the salesman said he'd have 
to get back to me.  He's coming out Friday to give me a quote, but they 
know I'm not interested in even trying it if they can not give me a 
written guarantee ahead of time.

It seems like Trane came up on here a while back but I've been unable to 
find a reference to it.
