Carrier Comfort Network Interface
The Carrier Comfort Network (CCN) communication bus wiring is supplied and installed by
the electrical contractor. It consists of shielded, 3-conductor cable with drain wire.
The system elements are connected to the communication bus in a daisy chain
arrangement. The positive pin of each system element communication connector must be wired
to the positive pins of the system element on either side of it. The negative pins must be wired
to the negative pins. The signal ground pins must be wired to the signal ground pins. See
Figure 22
for location of the CCN network connector (COMM1) on the processor module.
Note: Conductors and drain wire must be 20 AWG (American Wire Gage) minimum stranded,
tinned copper. Individual conductors must be insulated with PVC, PVC/nylon, vinyl,
Teflon, or polyethylene. An aluminum/polyester 100% foil shield and an outer jacket of
PVC, PVC/nylon, chrome vinyl, or Teflon with a minimum operating temperature range of
-4 F to 140 F (-20 C to 60 C) is required. See table below for cables that meet the
requirements.
