c. On 33ZCT56SPT thermostats, connect the remain-
ing wire (WHITE/CLR) to the T56 terminal on the
controller. Connect the other end of the wire to the
right most terminal on the SET terminal block.
d. In the control box, install a No. 6 ring type crimp
lug on the shield dlain wire. Install this lug under
the mounting screw in the upper right corner of the
controller (just above terminal TI ).
e. On 33ZCT56SPT thermostats install a jumper
between the two center terminals (right SEN and
left SET).
Wiring the Network Communication Service Jack -- See
Fig. 16-18. To wire the service jack, perform the following:
1. Strip back the jacket from the communication cable(s) for
at least 3 inches. Strip _/4-in. of insulation from each
conductor Remove the shield and septuate the dlain wire
from the cable. Twist together all the shield drain wires
and fasten them together using an closed end crimp lug or
a wile nut. Tape off any exposed bare wire to prevent
shorting.
2. Connect the CCN + signal wire(s) (RED) to Terminal 5.
3, Connect the CCN - signal wire(s) (BLACK) to
Terminal 2.
4. Connect the CCN GND signal wire(s) (WHITE/CLR) to
Terminal 4,
Befole wiring the C_urier proprietary network connection,
refer to the Connect the Carrier Communicating Network
Communication Bus section on page 23, for communication
bus wiring and cable selection. The cable selected must be
identical to the communication bus wire used for the entire
network.
The other end of the communication bus cable must be
connected to the remainder of the communication bus. If the
cable is installed as a T-tap into the bus, the cable length cannot
exceed 100 ft. Wire the service jack of the sensor in a &fisy
chain tu'rangelnent with other equipment. Refer to the Connect
the Carrier Communicating Network Communication Bus sec-
tion, page 23, for more details.

structions for information on installing and using the System
Pilot.
