Because unless you're in Super TIU mode, only one TIU can do the ALL session. If in Super mode, it doesn't matter which TIU you pick.
Hey Barry, I've never really used the "ALL" command much ,Does it work in all tiu zones at once in super? or do you have to select each tiu each time it changes tiu zones?
Gregg,
Does it work in all tiu zones at once in super?
Yes, it does.
or do you have to select each tiu each time it changes tiu zones?
No, you do not.
