system blows hot air when in cooling mode

[pghfanone]

So this was my wiring set up.  I have since put the white wire to the OB slot with the same result.  I have also switched the heat pump wire in the app from O to B and back.  Still blows hot air.

It looks like you do not have a heat pump system there is no O/B wire so this is just a Heat and AC system.

Put the wire back the way it is in the picture.

Then in settings reset the Nest. When it asks tell it the type of heating you have it should be ductwork and I assume natural gas heat.

I actually do have a heat pump with electric heat and originally had the blue wire connected to the *OB.

Thanks for replying.

Do you have a pic or the old tstat wiring before you removed anything?

What color was the O wire on the old tstat?

If you do not know what wire is OB then you need to go to the furnace and take cover off and look at the wire colors and what terminal screws they are on and match it up on the nest exactly the same.

But you will need a C wire also with that model Nest if it gives you power error messages. Looks like you do not have enough wire colors to have a C wire so you can run a new 8 conductor cable or use the Nest power adapter.
