System Manager
The System Manager is the central operator interface for the CV or CV-EX system. It
must also be connected correctly to the communications loop in order to view the system
status and configure or change setpoints. It must be supplied with 24 VAC power in order
to operate. The System Manager does not require addressing. The System Manager is
always connected to the “Local” loop. For the CV system, this is the only loop on the
system. The System Manager can be connected anywhere on the CV communications
loop. In contrast, the CV-EX has two types of loops—the “Network” and “Local” loops.
The System Manager must be connected to the local loop on the CV-EX system. It will
not function correctly if connected to the network loop! See Figure 4-6 for wiring and
component location information for the System Manager.
Notes:
1.) 24 VAC Must Be Connected So
That All Ground Wires Remain
Common.
2.) All Wiring To Be In Accordance
With Local And National Electrical
Codes And Specifications.
3.) All Communication Wiring To Be
2-Conductor Twisted Pair With
Shield. Use Belden #82760 Or
Equivalent.

The Ideal Recommended Location For The System Manager Is As The First
Device On The Local Loop. The System Manager May Be Connected To The
Local Loop At Any Point On The Local Loop.
For CV Systems, Connect To Any
CV Controller On The Local Loop
Or To The CommLink. For The
CV-EX System, Connect To Any
Controller On The Local Loop Or
To The Local Loop Terminal On
The MiniLink.
Do Not Connect To The
Network Loop On CV-EX
Systems!
