You can tell if a room has been added to a group by the "G" icon next to the room.
To remove a group from the list, click the Delete button above the Groups list. To
remove a room from a group, click Delete room from group. When you've defined
all your groups, click Next.
The Enclosures screen is where you specify the room in each group where an
enclosure will be located. Here you highlight the group and then click the check box
next to the room where you want to place the enclosure. You should have one room
checked off for each group you've defined.
The Processor screen is where you select the location of the control system, usually
the PAC2. Here you will see a list of rooms containing an enclosure. Select the check
box next to the room where you want to place the control system.
