Heat pump or not?
I attempted to instal a nest thermostat I noticed I have a wire in the O terminal and from what I’ve read this is for the heat pump. However when I put the wire from the O terminal on the old stat to the * O/B terminal on the nest stat when the heat came on my outside unit came on this never happens and cold air came through the ducts. Sos I select the wrong settings while configuring my nest stat?
Everything points to it not being a heat pump unit but why would there be a wire in the O terminal
