Carrier GEMINI 38APS025-065 Installation Instructions Manual page 64

Units on the CCN can be monitored from the space using
the RJ11 connector provided with the space sensor, if desired.
To wire the RJ11 connector into the CCN (Fig. 26):
IMPORTANT: The cable selected for the RJ11 connector
wiring MUST be identical to the CCN communication bus
wire used for the entire network. Refer to Table 5 for
acceptable wiring.
1. Cut the CCN wire and strip ends of the red (+), white
(ground), and black ( ) conductors. (If another wire color
scheme is used, strip ends of appropriate wires.)
2. Insert and secure the red (+) wire to terminal 5 of the
space temperature sensor terminal block.
3. Insert and secure the white (ground) wire to terminal 4 of
the space temperature sensor.
4. Insert and secure the black ( ) wire to terminal 2 of the
space temperature sensor.
5. Connect the other end of the communication bus cable to
the remainder of the CCN communication bus.
NOTE: See Fig. 27 for space temperature averaging.
