  • Can you post a wiring diagram for your heat pump? Something's quite goofy with the O and B wires -- normally, you only have *one* wire from your 'stat to your heat pump's reversing valve. – ThreePhaseEel Jul 16 '16 at 19:24

    Hello, and welcome to Stack Exchange. Big points for photographing the original installation; most people disassemble everything and only then start wondering how to install the replacement. – Daniel Griscom Jul 16 '16 at 20:05
