7.6 Setup System - Setup Zones
The AC8 has four zones that may be used to define different areas—rooms or sections of a room. If set
up with four zones, the AC8 effectively performs as four separate units, controlling each zone sepa-
rately, for example, using a different rotation sequence for devices in each zone.
A single zone may have one to eight outputs associated with it. The
minimum number of outputs per zone is one, and the maximum for all
zones combined is eight.
By default, the AC8 is configured to have one zone with four outputs:
Zone 1 has four associated outputs and Zones 2-4 have none.
To set up zones:
Log In and Choose Setup System
• From the Main Menu, use the arrows ↑↓ to choose System and
Control, then press Enter ↵ (see 7.1 - Login for help) .
• Enter your password at the Login screen.
• From the System and Control Menu, use the arrows
↑↓ to choose
Setup System, then press Enter ↵ .
Select Setup Zones
• From the Setup System Menu, shown at right, use the arrows ↑↓ to
choose Setup Zones and press Enter ↵ .
7.6.1 Set Up a Zone
• From the Setup Zones Menu, choose a zone—for example,
Zone 1—and press Enter ↵ .
• In the Number of Devices screen, use the arrows ↑↓ to select the
number of outputs for this zone, then press Enter ↵ . The example
at right shows four outputs in Zone 1.
Guidelines for Setting Up Zones
• The AC8 assigns outputs to zones in numerical order, based
on entries in the Number of Devices screen. For example:
• The total number of outputs for all zones cannot exceed 8.
If you try to enter more than 8 devices in total, Message 1 appears
(shown at right). Press Escape to return to the Setup Zones menu.
• Zones must be set up in order, starting with Zone 1.
If you try to enter devices for Zone 2 before Zone 1 has any outputs,
Message 2 appears (shown at right). Press Escape and set up
Zone 1 before attempting to set up Zone 2.
• Remove outputs in descending order, ending with Zone 1.
If you try to remove all devices from Zone 1 before Zone 2,
Message 3 appears (shown at right). Press Escape and remove
devices from Zone 2 before removing devices from Zone 1.
Table 18 shows the default number of outputs for each zone.
