SAFETY CONSIDERATIONS

Air-handling equipment will provide safe and reliable service
when operated within design specifications. The equipment
should be operated and serviced only by authorized person­nel who have a thorough knowledge of system operation,
safety devices and emergency procedures.

Good judgement should be used in applying any manufac­turer’s instructions to avoid injury to personnel or damage to
equipment and property.

Disconnect all power to the unit before performing mainte­nance or servic e. Unit may automati cally start if pow er is
not disconnected. Electrical shock and personal injury
could result.

Damage to equipment may result. An individual field­supplied 24-vac power transformer is required for each
PremierLink controller. The transformer must be less than
100 va to meet UL (Underwriters’ Laboratories) Class 2.

The PremierLink Controller is a field re trofit split system
control compatibl e with the Carr ier Comfort Network (CCN ).
This control is designed to allow users the access and ability to
change factory-defined settings thus expanding the function of
the standard unit control board. The complete PremierLink
package (part number 33CSPREMLK) consists of a control
circuit board with plastic cover and label, wire harnesses, spade
connectors, wire nuts and 4 mounting screws.

For specific details about sensors, refer to the literature
supplied with the sensor.

SP AC E TEMPERATURE (SP T ) SENSOR — A field-suppl ied
Carrier space temp erature sensor is required to maintain space
temperature in sensor mode. There are three sensors available for
this application:

• 33ZCT55SPT, Space Temperature Sensor with Override

Button

• 33ZCT56SPT, Space Temperature Sensor with Override

Button and Set Point Adjustment

• 33ZCT58SPT, T58 Communicating Room Sensor with

Override Button, Set Point Adjustment, and Manual Fan

control

If controlling an economizer in the thermostat mode, a duct
sensor must be mounted in the return air duct and wired to SPT
input.

SUPPLY AIR TEMPERATURE (SAT) SENSOR — The
PremierLink controller must be connected to a field-supplied
supply air temperature (SAT) sensor (part number
33ZCSENSAT) to monitor the temperature of the air delivered.

The SAT consists of a the rmist or enca sed within a stainles s
steel probe. The probe is 6 in. nominal length. The SAT sensor
has 114 in. of unshielded, plenum-rated cable (2 conductors,
22 AWG [American Wire Gage]). The sensor range is –40 to
185 F with a nominal resistance of 10,000 ohms at 77 F. The
sensor measures temperature with an accuracy of ±0.36 F.

The space temperature sensors are used to measure the
building interior temperature. The T58 communicating room
sensors measure and maintain room temperature by communi­cating with the controller. Sensors should be located on an
interior building wall. The sensor wall plate accommodates the
NEMA (National Electrical Manufacturers Association)
standard 2 x 4 junction box. The sensor can be mounted direct­ly on the wall surface if acceptable by local codes.

Do not mount the sensor in drafty locations such as near air
conditioning or heating ducts, over heat sources such as base­board heaters, radiators, or directly above wall-mounted light­ing dimmers. Do not mount the sensor near a window which
may be opened, near a wall corner, or a door. Sensors mounted
in these areas will have inaccurate and erratic sensor readings.

The sensor should be mounted approximately 5 ft from the
floor, in an area representing the average temperature in the
space. Allow at least 4 ft between the sensor and any corner
and mount the sensor at least 2 ft from an open doorway. The
SPT sensor wires are to be connected to terminals in the unit
main control board.

Install the sensor as follows:

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 fas te ner s.

4. Feed the wires from the electrical box through the open­ing 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.

NOTE: Sensor may also be mounted directly on the
wall using 2 pl astic anchors and 2 sheet met al screws
(field-supplied).

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
communication cable may be used. If the set point adjust­ment (slidebar) is not required, then an unshielded, 18 or
20 gage, two-conductor, twisted pair cable may be used.

The CCN network service jack requires a separate,
shielded CCN communication cable. Always use sepa­rate cables for CCN communication and sensor wir­ing. (Refer to Fig. 5 for wire terminations.)

7. Replace the cover by inserting the cover at th e top of t he
mounting plate first, then swing the cover down ove r th e
lower portion. Rotate the two Allen head screws counter­clockwise until the cover is secured to the mounting plate
and locked in position.

NOTE: See Table 3 for thermistor resistance vs temperature
values.

Wiring the Space Temperature Sensor

— To wire the sensor,

perform the following (see Fig. 3-5):

1. Identify which cable is for the sensor wiring.

2. Strip back the jacket from the cables for at least 3 inches.

1

Strip

/4-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 to (BLU) wire on

J6-7 analog connector on the controller. Connect
the other end of the wire to t he left term inal on the
SEN terminal block of the sensor.

b. Connect another wire from the cable to (BRN)

J6-6 analog connector on the controller. Connect
the other end of the wire to the remaining open ter­minal on the SEN terminal block.

c. On 33ZCT56SPT thermostats, connect the remain-

ing wire to the (BLK) STO on J6-5 connector on
the controller. Connect the other end of the wire to
the SET terminal on the sensor.

d. In the control box, install a no. 10 ring type crimp

lug on the shield drain wire. Inst all this lug under
the mounting screw of the PremierLink controller.

e. On 33ZCT56SPT thermostats install a jumper

between the two center terminals (right SEN and
left SET). See Fig. 4.

f. Refer to Fig. 5 for 33ZCT58SPT thermostat wir-

ing. Once the T58 sensor is powered up, all of the
graphic icons on the LCD (liquid crystal display)
display will be energized for a few seconds. The
graphical icons will then turn off and the T58 sen­sor will energize the three-digit numeric display.
The value “58” will be displayed for two seconds.
After 2 seconds, the LCD will display the default
space temperature value.

NOTE: See Fig. 6 for space temperature sensor averaging.

SUPPLY AIR TEMPERATURE (SAT) SENSOR INSTAL­LATION — The 33ZCSENSAT supply air temperature sensor
is required for controller operation. The sensor consists of a
thermistor encased within a stainless steel probe. The SAT
sensor probe is 6-in. nominal length with 114 in. of unshielded,
2-conductor 18 AWG twisted-pair cables. The sensor tempera­ture range is –40 to 245 F with a nominal resistance of
10,000 ohms at 77 F . The sensor measures accuracy of ±0.36 F .
The SAT sensor is supplied with a gasket and 2 self-drilling
mounting screws.

NOTE : The sensor must be mounted in the discharge of the
unit, downstream of the cooling coil and heat exchanger. Be
sure the probe tip does not come in contact with any of the
unit surfaces. See Fig. 11 for mount ing location.

Do not run sensor or relay wires in the same conduit or race­way with Class 1 AC service wiring. Do not abrade, cut, or
nick the outer jacket of the cable. Do not pull or draw cable
with a force that may harm the physical or electrical properties.
A void splices in any control wiring.

Perform the following steps to connect the SAT sensor to
the PremierLink™ controller:

1. Locate the opening in the control box. Pass the sensor
probe through the hole.

2. Drill or punch a

1

/2-in. hole in the supply air duct.

3. Use two field-supplied, self-drilling screws to secure the
sensor probe to the duct.

4. Connect the sensor leads to the PremierLink controller’s
wiring harness J6-3,4 board at the terminals labeled SAT
(ORN) and GND (BRN).

Typical Wiring (33ZCT58SPT)

Perform the following steps if state or local code requires
the use of conduit, or if your installation requires a cable length
of more than 8 ft:

1. Secure the probe to the duct with two field-supplied self­drilling screws.

2. If you are extending cable length beyond 8 ft, use plenum
rated, 20 A WG, twisted pair wire.

3. Connect the sensor leads to the PremierLink™ control­ler’s wiring harness terminal board at the terminals la­beled SAT (ORN) and GND (BRN).

4. Neatly bundle and secure excess wire.

INDOOR AIR QUALITY CO

SENSOR INSTALLATION

2

(IAQ) — The indoor air quality sensor accessory monitors
carbon dioxide (CO2) levels. This information is used to moni­tor IAQ levels. Three types of sensors are provided. The w all
sensor can be used to monitor the conditioned air space.
Sensors use infrared technology to measure the levels of CO
present in the air. The wall sensor is available with or without
an LCD readout to display the CO2 level in ppm.

The CO
2000 ppm and a linear mA output of 4 to 20. Refer to the
instructions supplied with the CO

sensors are all factory set for a range of 0 to

2

sensor for electrical require-

2

ments and terminal locations.

To accurately monitor the quality of the air in the condi­tioned air space, locate the sensor near a return air grille (if
present) so it senses the concentration of CO

leaving the

2

space. The sensor should be mounted in a location to avoid
direct breath contact.

Do not mount the IAQ sensor in drafty areas such as near
supply ducts, op en window s, fans , or over hea t sources . Allow
at least 3 ft between the sensor and any cor ner. Avoid mo unting
the sensor where it is influenced by the supply air; the sensor
gives inaccurate readings if the supply air is blown directly onto
the sensor or if the supply air does not have a chance to mix
with the room air before it is drawn into the return airstream.

Wiring the Indoor Air Quality Sensor

— To wire the sensors
after they are mounted in the conditioned air space or outdoor
location, see Fig. 7 and 8 and the instructions shipped with the
sensors. For each sensor, use two 2-conductor 18 AWG

(American Wire Gage) twisted-pair cables (unshielded) to con­nect the separate isolated 24 vac power source to the sensor and
to connect the sensor to the control board terminals. T o connect
the sensor to the control, identify the positive (4 to 20 mA) and
ground (SIG COM) terminals on the sensor. Connect the
4-20 mA terminal to terminal IAQ (RED) and connect the
SIG COM terminal to ter mina l GND ( BRN).

OUTDOOR AIR QUALITY CO

SENSOR INSTALLA-

2

TION (OAQ) — T h e Outdoor Air CO2 sensor is designed to
monitor carbon dioxide (CO2) levels in th e air and interface
with the ventilation damper in an HVAC system. The OAQ
sensor is packaged with an outdoor cover. See Fig. 12 and 13.

The outdoor air CO

sensor must be placed in an area that is

2

representative of the entire conditioned space. A mounting
height of 6 feet is recommended. For installation where it is not
necessary to reach the control, it may be mounted higher on the
wall or on the ceiling, provided the location represents a good
sampling of air.

Wiring the Outdoor Air CO

Sensor — Power requirements

2

are 18 to 36 vac RMS 50/60 Hz; 18 to 42 vdc polarity protected/
dependent; and 70 mA average, 100 mA peak at 24 vdc. All
system wiring must be in compliance with all applicable local
and national codes. A dedicated power supply is required for
this sensor. A two-wire cable is required to wire the dedicated
power supply for the sens or . The two wires s hould be connected
to the power supply and terminals 1 and 2. To connect the sen­sor to the control, identify the positive (4 to 20 mA) and ground
(SIG COM) terminals on the sensor. Connect the 4 to 20 mA
terminal OAQ (BLU) terminal J5-2. Connect the SIG COM ter­minal to terminal GND (BRN) terminal J5-3. See Fig. 12.

OUTDOOR AIR TEMPERATURE SENSOR (Fig. 14-17) —
The OAT sensor must be located properly. The sensor must be
installed immediately upstream from outdoor air damper
where it will accurately sense th e temperature of the outdoor
air entering the mixing box. See Fig. 14 and 15. For applica­tions without economizer, the sensor may be located in the out­door air duct near the outdoor air intake (Fig. 15) or on the
exterior of the building. The thermistor has a range of –40 to
245 F and a resistance of 10,000 ohms at 77 F.

Do not mount the sensor in direct sunlight. Inaccurate read-

ings may result. Do not mount the sensor near the exhaust from

2

air-handling units or compressors, near leakage drafts of indoor
air, or near shrubbery or trees, or under direct water runoff.

If the sensor is to be mounted in the outdoor air duct, a field-

supplied 2 x 4-in. by 1

1

/2-in. deep electrical box is required.
Remove the cover and enter the knockout from the rea r of the
box. Install the sensor through the opening so that the sensor
leads are inside the electrical box. Secure the sensor to the elec­trical box using a field-supplied

1

/2-in. conduit nut. Drill a
13/16-in. hole in the outdoor air duct about a foot upstream of
the outdoor air damper. Apply a 1/4-in. bead of silicone type
sealer around the opening and install the sensor through the
hole. Secure the electrical box to the duct using 2 field­supplied, No. 10 sheet metal screws. See Fig. 17.

If the sensor is installed outdoors, a field-supplied

1

/2-in. LB
type conduit body, gasket, cover , and 1/2-in. EMT compression
connector are required. Install the OAT sensor into the opening
at the end of the LB conduit body. Install the

1

/2-in. EMT
connector into the rear opening. Tighten each securely to
prevent water leakage into the assembly. Mount the assembly
onto the

1

/2-in. EMT conduit and secure by tightening the
compression connector nut. After the sensor wiring is complet­ed, secure the gasket and cover in place using the screws
provided with the cover. See Fig. 16.
