Installation Tips
Take a few moments to review the following before beginning installation of the Auto-
Zone Plus System.
• Familiarize yourself with all system components and review all documentation. Pay
special attention to “Cautions” and “Warnings” since these may keep you from
experiencing unnecessary problems.
• Before installing zone dampers, be sure to tag each damper with its appropriate
location. A set of labels is included with this manual. It is also best to set the zone
controller address switches before mounting in drop ceilings. Use the Zone Address
Worksheet to list all zone locations. This will assist you greatly when setting up the
system.
• Be sure and install all wiring according to local, state, and national codes.
• Pay close attention to communication wiring since the most common mistakes are
made in this area. Polarity is the most important rule. Make notes on your wiring
diagrams as to which color wire you will be using on each terminal.
Note: Auto-Zone Plus systems use two separate types of communications loops. The
Network Loop connects only to the Zone Managers and the CommLink IV.
The Local Loops connect between the Zone Manager and the Zone Controllers
for that HVAC unit. Each Zone Manager has its own Local Loop for
connection to associated Zone Controllers and any additional Constant
Volume units and the System Manager.
Do not connect Zone Controllers, Constant Volume Units
or the System Manager to the Network Loop!
• When in doubt - ask! Contact your local Auto-Zone distributor if you have any
questions. The only dumb questions are the ones you don’t ask.
• Remember - each electronic device contains only one puff of smoke. If you release it,
you have voided the warranty! So please be careful and pay attention.
