There's a jumper from R to C?

On the mounting bracket (see
http://www.white-rodgers.com/wrdhom/pdfs/06_Cat_pages/Cat_06_pg0161.pdf)
wires go from the R and C terminals over to a block. Not sure what the
schematic is for that block, but I only connected the furnace R terminal
to the corresponding R terminal on the bracket, and the display did not
light up. It needs power (of course) so without a connection back to
the common side of the transformer there's no continuity.

If they at least had a diagram showing a typical setup it would be
clear(er), but currently it's a bit of a mystery.

One thing I noticed is that it doesn't take batteries and there was no
display when I hooked it up. I hooked up the R to the "R" terminal,
which already had a red wire in it which goes over to a jumper (along
with a black wire, which goes from the jumper to the "C" terminal).

Thermostat wiring......
It rocket science. Not everyone can do it.

Hi,
I think it was meant to say one wire from R and another from C.
Original poster, please read the manual B4 anything. If it can
handle multi-stage, sure it can handle single stage unit.

Hi,
Not at set time but Honeywell Vision Pro has an option to cycle the fan
at certain interval.
