Install and wire the space temperature sensor as follows:

NOTE: Space temperature sensor will be identified as T55 or
T56. Refer to Control Sequence Drawings to determine which
SPT is part of the particular control package being installed.
(The difference between T55 and T56 is that T56 includes set
point adjustment capability.)

1. Locate the two Allen type screws at the bottom of the

sensor.

2. Turn the two screws clockwise to release the cover from

the sensor wall mounting plate.

3. Lift the cover from the bottom and then release it from

the top fasteners.

4. Feed the wires from the electrical box through the open-

ing in the center of the sensor mounting plate.

5. Using two no. 6-32 x 1 mounting screws (provided with

the sensor), secure the sensor to the electrical box.

6. Use 20 gage wire to connect the sensor to the controller.

The wire is suitable for distances of up to 500 ft. Use a
three-conductor shielded cable for the sensor and set
point adjustment connections. The standard CCN com-
munication cable may be used. Refer to Table 8. If the set
point adjustment (slide-bar) is not required, then an un-
shielded, 18 or 20 gage, two-conductor, twisted pair cable
may be used. Refer to Table 7.
The CCN network service jack requires a separate,
shielded CCN communication cable. Always use sepa-
rate cables for CCN communication and sensor wiring.
(Refer to Fig. 19 and 20 for wire terminations.)

7. Replace the cover by inserting the cover at the top of the

mounting plate first, then swing the cover down over the
lower portion. Rotate the two Allen head screws counter-
clockwise until the cover is secured to the mounting plate
and locked in position.

8. For more sensor information, see Table 6 for thermistor

resistance vs temperature values.

NOTE: Clean sensor with damp cloth only. Do not use
solvents.

Table 7 — Recommended Sensor and Device

Wiring

NOTE: Wiring is 20 gage, 2 conductor twisted cable.

WIRING THE SPACE TEMPERATURE SENSOR AND
SET POINT ADJUSTMENT SLIDEBAR — To wire the sen-
sor and slidebar, perform the following:

1. Identify which cable is for the sensor wiring.
2. Strip back the jacket from the cables at least 3 inches.

-in. of insulation from each conductor. Cut the

shield and drain wire from the sensor end of the cable.

3. Connect the sensor cable as follows:

a.

Connect one wire from the cable (RED) to the
SPT terminal on the controller. Connect the other
end of the wire to the left terminal on the SEN ter-
minal block of the sensor.

b.

Connect another wire from the cable (BLACK) to
the ground terminal on the controller. Connect the
other end of the wire to the remaining open termi-
nal on the SEN terminal block.

c.

For T56 sensors, connect the remaining wire
(WHITE/CLR) to the T56 terminal on the control-
ler. Connect the other end of the wire to the right
most terminal on the SET terminal block.

d.

In the control box, connect the cable shield to
J1-3, equipment ground.

e.

Install a jumper between the two center terminals
(right SEN and left SET).

WIRING THE CCN NETWORK COMMUNICATION
SERVICE JACK — To wire the service jack, perform the
following:

1. Strip back the jacket from the CCN communication ca-

ble(s) at least 3 inches. Strip

-in. of insulation from

each conductor. Remove the shield and separate the drain
wire from the cable. Twist together all the shield drain
wires and fasten them together using an closed end crimp
lug or a wire nut. Tape off any exposed bare wire to pre-
vent 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.

PRIMARY AIR TEMPERATURE SENSOR INSTALLA-
TION — A primary air temperature (PAT) sensor is used on a
zone controller which is functioning as a Linkage Coordinator
for a non-CCN Linkage compatible air source. The part num-
ber is 33ZCSENPAT. See Fig. 21. The sensor is also available
as field-supplied accessory.

When used on a zone controller, try to select a zone control-

ler which will allow installation of the PAT sensor in the main
trunk, as close to the air source as possible. See Fig. 22.

To mount the PAT sensor, remove sensor cover.

1. Drill a

-in. hole in supply duct.

2. Using field-supplied drill tap screw, secure sensor to duct.
3. Connect sensor to zone controller using field-supplied

2-conductor cable. Refer to Table 7.

4. Use field-supplied wire nuts to connect cable to sensor.
5. At zone controller, connect sensor wires to PAT and GND

terminals.
