Thanks. I had a feeling that the damn thing was compatible. There's $80 down
the drain!(anyone want to buy two brand new Lux ATX 1500 digital
thermostats?) Looks like I'm headed to Ebay.

Try Tim's suggestion before sending it to e-Bay:
Assuming your furnace is wired with standard colors, I'd try Red to 'R',
white to 'W' and green to 'G'
