They are the same. Later production lines added a /37 (US) country code for them.

The reason the manuals (all are on the site here) are so small is because the control panel (aka remote) is intended to be programmed by a professional installer. Philips had a certification program where they provided additional information about more advance capabilities. The editor is publicly available on this site (see the Pronto Pro Files section).

Earlier versions of the editor had a larger help file and the last version of the editor uses a Robohelp dll and web help which does not run on windows that well.

If you are installing the editor, I recommend a 32 bit windows OS but others have no issues with 64bit. Windows 10 has presented some people with challenges during download from PC to the unit.
