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.
