Hitting the logo and entering installer code doesn't work on the TS1.

You cannot program from the TS1 in any event, but what that is for is the user code. It is a shortcut to disarm system, and doubles as a way to enter the 'secret' duress code even if system is disarmed.

On the main panel, that logo has a slightly different purpose- on a disarmed panel it give access for the installer code, on a armed panel it is a shortcut like on the TS1 for a disarm/duress user code.
