Douger,

Since it runs fine with the old thermostat, the problem has to be in
the new one. That's the only thing you've changed.

Yes, I came to the same conclusion.

I've had the old Honeywell connected & it works fine, save for the sticky
"down" button; which is why I needed to replace it to begin with. It's stuck
@ 71 degrees.

I guess I'll look for a thermostat with just the G - R - W - Y wires but,
it's hard to see the connections without opening the package.
