I have a RUUD heatpump/AC unit with manual thermostat.
Inside unit is UBHC-17J11SHG, outside unit is UPMC-030JAZ, thermostat is T874R1434.
New thermostat is Honeywell Vision Pro 8000 series (TH8320U1008).
When I remove the faceplate on the existing thermostat, I see the following wires connected on the left side from top to bottom:
Yellow
White
bare wire
Lt. Blue
Red
Black (or Dk. green).
Connected the the mercury thermometer is white, blue and yellow on top.
Connected to the bottom is red and black (or Dk, green),
I need to know what wires go where on the Honeywell wiring block.
Thanks,
James Andrus

Hopefully there are markings on the old t-stat as to what terminal is what.
on the honeywell 8000 use the heat pump labeling and then the standard wiring would be
R- red
AUX-white
Y- yellow
B- O/B
C- black
G- green
There should not be a bare wire, it probably just has the insulation stripped back way too far.
You should probably open the furnace and compare the terminal label in the furnace to the wire color. normally yellow and blue pass through the furnace and are wire nutted to wires going to the outdoor unit. In the furnace the white wire will connect to the w or w1 terminal. also, you will need to set the Honeywell stat to have the following parameters.
170-7
190-1
200-0
other parameters that I did not specify, you may read the manual and make your own decision but I recommend factory settings for the other parameters
