APPENDIX A: SYSTEM CONFIGURATION
Options
The VCCX2 Controller can be used as a stand-alone system (one
VCCX2 Controller only), connected together on an interconnected
system (multiple VCCX2 Controllers only), or connected together
on a network system (multiple VCCX2 Controllers, VAV/Zone
Controllers, or add-on controllers) to form a complete controls
system that can be programmed and monitored with one or more
of the available operator interfaces.
Operator Interfaces
Operator interfaces are designed to provide for programming and
monitoring of VCCX2 Controller(s) and/or any VAV/Zone or add-
on controller(s) connected to the system.
Stand-Alone System
The stand-alone system is used with a single VCCX2 Controller.
Programming and status monitoring are accomplished by selecting
and installing one or more of the operator interfaces.
Interconnected System
The interconnected system is used when there are multiple VCCX2
Controllers. With this system, connect the controllers together using
AAON communications wire or 18-gauge, two-conductor, twisted
pair with shield wire (Belden #82760 or equivalent). This allows
for all controllers that are connected on the communications loop
to be programmed and monitored from one or more of the available
operator interfaces connected on the communications loop.
Networked System
For a networked single loop system, a range of one to 59 VCCX2
Controllers sharing information, connect the controllers together
using AAON communications wire or 18-gauge, two-conductor,
twisted pair with shield wire (Belden #82760 or equivalent). The
networked single loop system requires either a MiniLink PD
communication interface and/or CommLink communication
interface be purchased and wired into the communications loop to
the VCCX2 Controllers.
The networked multiple loop system is used for a system with more
than 59 VCCX2 Controllers and/or are using multiple VCCX2
Controllers that are connected to VAV/Zone controllers. These
groups of controllers are broken into multiple “local loops” that
connect to each other via the “network loop.” Each MiniLink PD
handles its specic local loop’s communications requirements.
The CommLink communications interface handles all the
communications between the individual MiniLink PDs to form
the network loop. Up to 60 local loops can be connected with this
conguration. This provides the capability for over 3,500 controllers
to be networked.
