PJ is an error that has to do with the outdoor unit not matching the indoor unit. This means the outdoor board thinks it's a 2 ton unit and the indoor thinks it's a 1 ton unit. (Just throwing those numbers in)...but, the indoor is not matching the outdoor. You need to read the manual and go through the setup process.

Signal transmission error (between indoor and outdoor units) which means a faulty indoor or (more likely) faulty outdoor controller board. Call a tech.
