The C wire is what we'd fondly call a B- or common, or ground. The
only reason a thermostat needs a C wire is if the thermostat is
powered by the furnace transformer. Otherwise, they work fine without
a common wire.
Thanks for letting us know that things worked out well. I like a good
laugh now and again, but I do try to be serious about heating advice
(well, most of the time).

You can't shout down a troll.
You have to starve them.
I solved the problem but I do want to thanks all the folks that took
the time to provide a response. Unfortunately, this user groups
attracts a number of childish post so in the future I will seek a
moderated forum that keeps the Ken and Barbie crowd out.
According to Hunter, the C wire is a common wire and is not used. That
makes my current system a four wire system and solves the problem.
Thanks agian to those that tried to supply real help.

Since when did the manufacturers start putting BATTERIES(B-) in 24v AC
control systems???

Hey, it's terminology I've heard. I can't explain it if folks want to
use the wrong term.

Your welcome.
I agree that people like Stormin Normin are trouble
in these newsgroups, but people like me, the type that
give out diagnoses over the internet, are trying to
make it better.

Hunter makes great ceiling fans, but their thermostats suck. Honeywell makes
great thermostats, but you get what you pay for.
