Its just the translation that gets lost on AMs site.
Nicklfire is right in that he calls the ones without solenoids manual, although in essence the 2 regulators are the same just one has a cylinder pressure gauge and the other doesn't.
The regulator is just the main section of both setups there.
I am AMs biggest fan but I am not too keen on either of these regs as they will be shipped a long way and also they are from outside europe which may mean needing adaptors to fit euro cylinders!!
You should find out if and where you can get your cannister refilling and if they require you to rent or buy one of their branded cylinders etc before deciding on a refillable regulator. If you have trouble like I and many others do (the restrictions seem to be a lot tighter on bottled gasses these days) then you might consider going the disposable bottle route which would mean that this regulator would be of no use.
Research where you can get refills and what restrictions/conditions they have before you buy the equipment.
