Step 13 --Adjust Factory-Installed Options

PREMIERLINK TM CONTROL -- The PrelnierLink control-

ler is available as a special order from the facto U and is com-

patible with the Ctmier Comfort Network® (CCN) system.

This control is designed to allow usel_ the access and ability to

change factoly-defined settings, thus expanding the function of

the standard unit control board. Carrier's diagnostic stan&ud

tier display tools such as Navigator r_'_ device or Scrolling

Marquee can be used with the PremierLink controller.

The PremierLink controller (see Fig. 24) requires the use of

a C;urier electronic themiostat or a CCN connection for time

broadcast to initiate its internal timeclock. This is necessmy for

broadcast of time of day functions (occupied/unoccupied). No

sensors are supplied with the field-mounted PremierLink con-

trol. The factou-installed PremierLink control includes only

the supply-tfir temperature (SAT) sensor and the outdoor air

temperature (OAT) sensor as standmd. An indoor air quality

(CO2) sensor can be added as tin option. Refer to Table 8 for

sensor usage. Refer to Fig. 25 for PremierLink controller wir-

ing. The PremierLink control may be mounted in the control

panel or an men below the control panel.

NOTE: PremierLink controller version 1.3 and later is shipped

in Sensor mode. If used with a thermostat, the PremierLink

controller must be configured to Thermostat mode.

Install the Supply Air Temperature (SAT) Sensor -- When

the unit is supplied with a factou-mounted PremierLink con-

trol, the supply-air temperature (SAT) sensor (33ZCSENSAT)

is factory-supplied and wired. The wiring is muted from the

PlemierLink control over the control box, through a grommet,

into the fan section, down along the back side of the fan, and

_dong the fan deck over to the supply-air opening.

The SAT probe is wire-tied to the supply-air opening (on the

horizontal opening end) in its shipping position. Remove the

sensor for installation. Re-position the sensor in the flange of

the supply-air opening or in the supply air duct (as required by

local codes). Drill or punch a l/2-in, hole in the flange or duct.

Use two field-supplied, self-drilling screws to secme the sensor

probe in a horizontal orientation.

NOTE: The sensor must be mounted in the dischmge airstream

downstream of the cooling coil and any heating devices. Be

sure the probe tip does not come in contact with any of the unit

or heat surfaces.

Outdoor Air Temperature (OAT) Sensor -- When the unit is

supplied with a factoly-mounted PremierLink control, the

outdoor-air temperature sensor (OAT) is factory-supplied and

wired.

Install the Indoor Air Quality (CO2) Sensor -- Mount the

optional indoor air quality (CO2) sensor according to manufac-

turer specifications.

A sepmate field-supplied transformer must be used to

power the CO2 sensoc

Wire the CO2 sensor to the COM and IAQI terminals of J5

on the PremierLink controflec Refer to the PremierLink Instal-

lation, Start-up, and Configuration Instructions for detailed

wiring and configuration information.
