1.2 Auto-Zone - Plus System
The Auto-Zone - Plus system has more than one communications loop so it is important
to remember that
each loop must have it’s own master .
The main communications loop is the Network loop. It connects all of the Zone
Managers (with MiniLinks) to the CommLink II. Each Zone Manager also has its own
Local loop which connects it to the Zone Controllers and any CV Controllers or System
Managers which you have chosen to be connected to this particular loop. Study the loop
wiring diagrams until you understand this arrangement.
The CommLink II is always the master on the Network loop . You must be sure the
CommLink II is connected and functioning if you are troubleshooting the Network loop.
The MiniLink (mounted on the Zone Manager) is always the master on the Local loop .
The MiniLink will pass tokens to the Zone Manager and any Zone Controllers, CV
Controllers, or System Manager found on the Local loop.
The MiniLink continues to “pass the token” even if the Network loop is not functioning.
This is important to remember since the Zone Manager and the Zone Controllers will
continue to communicate even if the Network loop is damaged. This feature allows each
rooftop unit with a Zone Manager and its associated Zone Controllers to function
independently in the event of a “fault “ on another part of the system.
