750mv vs 12v Thermostat Question UPDATE 2
Updated 29 Nov-- Update 2--29 Nov: got it to work. Not clear on the thermostat voltage for these things whether I can use the cheaper version or what. I want it for my furnace only set-up in the R...

I got that RTH111 thermostat and the wiring instructions made no sense so I called Honeywell and was told this thermostat will not work with my 12v system etc etc.
So I told him other guys use it and they say it works, so where do I attach my two 12v wires--pos and neg?
He said you can try using just W and R and makes no difference which for pos and neg. He says if it does not work, it will not fry the thermostat, it just won't work. ( He said the CT53K is the model I should have for this job.)
Anybody who has posted above that theirs works want to comment on how you got it to work with your wiring? I will wait till later to hear about that before I try it out using the W and R. (He said never mind the jumper between R and Rc, just leave it there)
