Step 13 — Adjust Factory-Installed Options
PREMIERLINK™ CONTROL — The PremierLink control-
ler is available as a special order from the factory and is
compatible with the Carrier Comfort Network® (CCN) sys-
tem. This control is designed to allow users the access and abil-
ity to change factory-defined settings, thus expanding the func-
tion of the standard unit control board. Carrier’s diagnostic
standard tier display tools such as Navigator™ device or
Scrolling Marquee can be used with the PremierLink
controller.
The PremierLink controller (see Fig. 25) requires the use of
a Carrier electronic thermostat or a CCN connection for time
broadcast to initiate its internal timeclock. This is necessary for
broadcast of time of day functions (occupied/unoccupied). No
sensors are supplied with the field-mounted PremierLink
control. The factory-installed PremierLink control includes
only the supply-air temperature (SAT) sensor and the outdoor
air temperature (OAT) sensor as standard. An indoor air quality
(CO
2
) sensor can be added as an option. Refer to Table 8 for
sensor usage. Refer to Fig. 26 for PremierLink controller
wiring. The PremierLink control may be mounted in the
control panel or an area 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 factory-mounted PremierLink con-
trol, the supply-air temperature (SAT) sensor (33ZCSENSAT)
is factory-supplied and wired. The wiring is routed from the
PremierLink control over the control box, through a grommet,
into the fan section, down along the back side of the fan, and
along 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
1
/
2
-in. hole in the flange or duct.
Use two field-supplied, self-drilling screws to secure the sensor
probe in a horizontal orientation.
NOTE: The sensor must be mounted in the discharge 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 factory-mounted PremierLink control, the
outdoor-air temperature sensor (OAT) is factory-supplied and
wired.
Install the Indoor Air Quality (CO
2
)Sensor — Mount the
optional indoor air quality (CO
2
) sensor according to manufac-
turer specifications.
A separate field-supplied transformer must be used to
power the CO
2
sensor.
Wire the CO
2
sensor tothe COM and IAQI terminals of J5 on
the PremierLink controller. Refer to the PremierLink Installa-
tion, Start-up, and Configuration Instructions for detailed wiring
and configuration information.
