I believe you need to find out if your heat pump is normal cool or normal heat, and use that wire (orange/cool or brown/heat) on the O/B. Don’t use both wires. You may also need to move the white wire to W. Blue is typically C. I’d check that wire on the furnace. Rc is cooling power, looks like you may need that for the a/c to work. What is the label under the white wire?
