What does error code H12 mean on my Panasonic cs-s9pkv?

If your Panasonic Air Conditioner displays error code H12, it signifies that the indoor unit and outdoor capacity rank are mismatched. This is due to wrong models being interconnected. To resolve this, check the models of the indoor and outdoor units.
