Description of System Components
A typical Auto-Zone Plus system is comprised of the following basic components.
System Manager
The microprocessor based System Manager allows multiple Zone Managers and any
single-zone constant volume HVAC units to be programmed and monitored from a
central operator's panel. The System Manager is connected to the Auto-Zone Plus
communication network and can be wired to any local loop connection on the system.
The System Manager is mounted in an attractive, white plastic housing, suitable for wall
mounting. A four line by twenty character backlighted LCD display and membrane
keypad provide a user friendly interface. All system variables, setpoints, and values can
be viewed and modified from the System Manager. Menu driven programming makes the
Auto-Zone Plus easy to set up and operate without the need for specialized training.
CommLink IV
The OE361-12 CommLink IV Communications Interface allows computer access into the
Auto-Zone controls system and also provides communications across multiple local
communications loops on the control system.
The CommLink IV comes packaged in an attractive beige colored plastic enclosure. The
CommLink IV is powered by a small plug-in transformer that is included. Locally, an
optional on-site personal computer with Prism software installed may be connected to the
CommLink IV to provide direct access to system control parameters. A USB cable (6 ft.
long) is provided with the CommLink IV for connection to your computer.
