Features/Benefits

Available for wide range of

rooftop applications

The PremierLink™ controller is avail-

able as a field retrofit application and

can control one or several rooftop units

with (multiple controllers) from 3 to

25 tons. In addition, it has an integrated

economizer controller that eliminates

the need for a separate circuit board.

The PremierLink controller can be

installed on the following Carrier roof-

top units: 48/50HJ (3 to 12

tons),

48TF/50TFF (3 to 12

tons), and

48/50TJ (12

to 25 tons). Other

Carrier equipment and non-Carrier

equipment can also be controlled by

PremierLink controller. Contact Carrier

Factory Sales representative for more

information.

Flexibility for every application

The PremierLink controller is an ad-

vanced microprocessor-based control.

PremierLink is precision controlled to

send heating and cooling only when

needed, reducing energy use and oper-

ating costs.

Carrier Linkage Thermostat

compatibility

When connected to a Carrier Linkage

Thermostat, the PremierLink controller

can use occupancy schedules, zone tem-

perature, and set points from the ther-

mostat. The PremierLink controller

provides the thermostat with the unit’s

operating mode and supply air tempera-

ture for local display at the thermostat.

When used with the Linkage Ther-

mostat, the PremierLink controller pro-

vides local space temperature sensing,

(remote space temperature sensing and

averaging with up to 3 optional remote

room sensors), occupied and unoccu-

pied heat and cool set points, occu-

pancy scheduling with up to 8 time

periods, 12 holiday periods, network

time broadcast, occupied set point

range limiting, temperature compen-

sated start, and global occupancy. A sin-

gle Linkage Thermostat will have the

ability to interface with up to 8 rooftop

controls serving a single zone with the

ability to unlink if communications to

the linkage thermostat are lost.

Fast and reliable system moni-

toring with Navigator

Carrier’s unique, hand-held diagnostic

tool, Navigator, can be used with the

PremierLink controller. Instant access to

detailed information is provided to tech-

nicians. Access is available via an RJ-11

connection or a 3-wire connection to

the communication bus.

Navigator offers flexibility for fast

service. Technicians can monitor roof-

top operation from the rooftop’s main

control panel. Additional hardware or

controller configuration is required for

Navigator applications.

Additional control features

The PremierLink controller provides

additional control features such as

Occupied/Unoccupied scheduling

initialized via the network. The Premier-

Link controller offers override invoked

from a wall sensor during unoccupied

hours from 1 to 4 hours in 1-hour

increments.

The PremierLink controller offers

ventilation monitoring with an optional

ventilation sensor. The CO

venti-

lation sensor measures the amount of

ventilation needed by the space and a

proportional integral derivative loop

(PID) calculation makes adjustments to

the economizer minimum position dur-

ing occupied operation. The indoor

will be compared to an outdoor

reference before making adjust-

ments to the economizer minimum

position.

Using a space sensor with set point

adjustment, timed override and service

port jack, the PremierLink controller

will provide intelligent compressor stag-

ing and economizer operation.

Modulating control of the economizer

will assist mechanical cooling without

adversely affecting compressor perfor-

mance. Economizer assisted cooling is

determined from a comparison of space

temperature, outside air temperature

and an enthalpy switch input. The

switch input can also be used for differ-

ential enthalpy input, meeting ASHRAE

Standard 90.1.

The T58 Communicating Space tem-

perature sensor with service port jack

provides set point adjustment, timed

override, force fan and read equipment

mode and measures and maintains

room temperature by communicating

with the PremierLink controller.

Simple mounting and ease of

installation

The PremierLink controller has an inte-

grated plastic cover with secured with

two plastic tabs that can be removed for

ease of installation.

For ease of installation, PremierLink

controller is provided with removable

Molex connectors which include pigtails

for easy installation to unit or sensors

using spade connectors or wire nuts.

The removable connectors are designed

so that they can be inserted one way so

as to prevent installation errors. The

PremierLink controller also provides an

RJ-11 modular phone jack for the Net-

work Service Tool connection to the

module via the Carrier Comfort Net-

work (CCN) communications.
