The database includes the 49TX, which will probably give you most of the commands. You may have to learn a few though. If the Maestro uses IR, then it probably uses the same commands as the Spacer system. If it's RF, you won't be able to control it with the 3000 or any other universal remote.
You might want to download the MX-3000 editing software (which includes the IR database) and check it out.
