I have White-Rogers 1F95-371 multi-stage thermostat that I'd like to try and use with my plain vanilla residential furnace (Lennox).
Problem:
- I only need it to control heat (W), fan (G) and AC (Y) - The R and C terminals on the unit have red and black wires (respectively) soldered to a block which has 3 terminals on it (see http://www.white-rodgers.com/wrdhom/pdfs/06_Cat_pages/Cat_06_pg0161.pdf ) - If I connect W/G/Y plus the R wire, the display does not light up - presumably because it needs a full-time connection to T (transformer common)
Has anyone wired up one of these successfully and can I adapt it to my single-stage furnace?
-Pat

24V common lead is C. If your 'stat does not use battery you need 24V AC from transformer by connecting R and C(two wires) So altogether you have 5 wires to 'stat. I am no expert. Just replaced a few 'stats. I like Honeywell ones.

The funny thing about this thermostat is that the C and R terminals have wires going to a block. There's also a metal flange covering the top of the terminal, one would think to dissuade the user from connecting the red/black wires there and, rather, connect them at the block.

Okay, so how does one handle the R/C terminal connections (which go to a block)?

Hey, I musta drank too much beer and peed on my screen. otherwise, why would YOUR post look yellow, PAT?

yeah,
but I don't think it belongs here. I like just plain text in a newsgroup without background colors. poor choice of color anyway, in my opinion.

I post with Thunderbird in plain text and HTML.
Depending on your newsgroup client, you will see a white or parchment background.

I know the reason WHY it comes out as yellow (parchment actually) (HTML background color as specified below), http://www.december.com/html/spec/color1.html
I just don't know why you want it that way in a newsgroup.

I think I can handle the programming (have a degree in computer science).
It's the hot/common connections that I'm not sure about. The R/C terminals already have wires inserted and these wires go over to a block...which also has screw terminals.
Do I wire directly to the terminals (which have a metal flange partially covering them, as if to prevent you from using them) or to the block(s)?
The directions don't say ANYTHING about the on-board wires, other than don't remove them.

Its not rocket science, almost anybody can do it (except you)LOL A degree doesn't mean that you can walk and chew bubble gum at the same time. If you have a degree in computer science, you should be able to handle a simple wiring diagram, and hooking up 5 different colored wires. Whats the worse that can happen..... let the factory smoke out of a component?? blow a fuse?? make the heat and A/C come on at the same time?? The link you posted shows exactly where to hook up the wires, and you can't figure it out..... I guess your degree doesn't apply to simple wiring?? Call a local tech.

the link you posted, Pat, clearly shows that R (24VAC hot) and C (24VAC common) need to supply power to the thermostat itself. The block seems like an extension of the R C terminals as you describe them, and as the picture shows just as a matter of convenience in wiring. do you read 24VAC between R and C with your meter?
you need to follow Nooner's advice and get a competent tech there,me thinks
