I need help with wiring up the new thermostat. I have a Gas furnace heat with heat pump. Goodman Units. The old thermostat G=GREEN C=BLUE Y=YELLOW R=RED O=ORANGE b=BLACK E=WHITE. The new thermostat has g,c,y.e,r but O/B is one terminal so Im unsure how to finish up. The other options are w2/aux, k l/a,s,s u See image of new thermostat setup. So does the Orange wire go to o/b and the black wire??
Here are the pictures you requested. Appears black wire not used??
Thanks for all the help!!
Here is the final setup that I went with. Forgot to take picture so just used graphic on new setup.
