My current Braeburn 3000 non-programmable thermostate wire is as below: And I am not sure I have heat pump or just heat/cool(most possibility)
Wire Braeburn 3000 O --->O Y --->Y and jumper to W G --->G R --->RC and jumper to RH
Right now has question to rewire to my Honeywell RTH7500 for wire O and Y.
wire RTH7500 O ---> (O/B of heat pump, and W in conventional are the same) Y ---> (Y) G --->G R --->RC and manufacture jumper to R
Do I just simply connect O to O/B(W) and Y to Y(without jumper to W as current thermostate? I do appreciate your help.

Old = New O = O/B Y = Y G = G R = Rc & R
Do not jumper W to Y.
option 170 = 2 option 190 = 0

Thanks. Houston204. I will give a try early tomorrow morning. Do you have any idea what system do I have? heat pump?
Originally, I had Hunter 44550 thermostate and when my heater stops working, the contractor called by my home warranty came in to replace many things, including the themostate and do the rewire. I have no clue why he jumper Y to W and don't like the non-programmable thermostate Braeburn 3000. Bought RTH7500 but then get confused where to start.

It is wired for single stage heat pump. No backup or emergency heat. Be sure to configure option 170 and option 190.
