You need to pay a professional before your melt your transformer or fry your circuit board. It's one of those jobs that you either know how to do it, or you don't. You don't.

Can't tell you a thing... can't see it from here, cant see what equipment its controlling, or how its configured. Is it a heat pump?? gas heat?? dual fuel?? Are the control voltages the same between the system and the humidifier?? do they have seperate control power sources??

Your best bet is to call a local tech..... oh wait a minute... you got that H'well stat from the big box store... and the RS stat from the internet....... never mind

At least the poster is consistent. Bought the stat on the net, and looking for install instructions on the net, well, usenet that is.

We recognize good attributes where they are found.

I would contact the "Online" company you purchased it from and ask them. Bubba

How will you be paying for my expert advice and wiring instructions? Do you have a paypal account?

Actually humidifier manufactures suggest to mount humidistat in the return air duct to measure the humidity from the entire residence for a better coverage of moisture....so you must be too lazy to go the furnace to adjust the humidistat

hello folks... just to update that i got this figured out. imho, you don't need a professional to do this kind of stuff. it's just hooking up some wires and test ... what's so hard about that? anyway, thanks to internet (full of information), i know exactly what my problem was...

I highly recommend this site:

Apparently the "simple" task had sufficient difficulty that you had seek professional help.

Yes, but do you "UNDERSTAND" why?
