Question about Honeywell Air Conditioners
Typically if you have a yellow wire in the "y" terminal blue is used as common or "c". As far as your jumper from rc to rh, that will depend upon what type of heat you have. If all of your heat and cooling come from your packaged unit outside, yes you will need the jumper. If this does not work maybe you have a bad breaker or transfomer.

4-wire typical wiring of a thermostat is: Y (Yellow) G (Green) W (white) and R (red). Inspect the thermostat to see if it has a jumper from R1 to R2. If not, put your red wire on R2. On a 5-wire thermostat you may have a blue wire. This will go to the common terminal (usually C but sometimes B) check the inline fuse in the air handler to see if it has blown. Replace it only after wiring the thermostat correctly.

Jumper R to Rc and hook hot wire from transformer to R usually red wire
O = Reversing valve probably white or orange If you get heat when calling for cool or Vice Versa then switch wire from O to the B terminal.
Y = Contactor usually yellow
G = Blower usally green
Jumper Aux to E need to go to unit and use the wire that goes to your Auxiliary or 2nd stage heat
L = Light if you have this terminal on your unit then hook it up.
C = Common from transformer usually black, if you have this terminal on your unit hook this wire up.
Make sure you go to your unit and only hook these wires up if they go to these locations.
