Hi everyone,
I bought a new Honeywell RTH6580WF.
We have a heat pump with an older Honeywell without Wi-Fi.

Without making this whole replacement too complicated and over thinking it, can this wiring from the original be repeated, but with the hidden blue common wire attached on the new one, and still have everything working?

Thanks for the help! The compatibility is very confusing, yes and no on the aux heating. Our heat pump is a 2014 AirTemp VQ7RD.
