Step 10 — Adjust Factory-Installed Options
PREMIERLINK™ CONTROL — The PremierLink control-
ler is available as a special order from the factory and is com-
patible with the Carrier Comfort Network® (CCN) system.
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. 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. 20) 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 con-
trol. 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 4 for
sensor usage. Refer to Fig. 21 for PremierLink controller wir-
ing. 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 control,
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 op-
tional indoor air quality (CO
2
) sensor according to manufactur-
er specifications. A separate field-supplied transformer must be
used to power the CO
2
sensor.
Wire the CO
2
sensor to the COM and IAQI terminals of J5
on the PremierLink controller. Refer to the PremierLink Instal-
lation, Start-up, and Configuration Instructions for detailed
wiring and configuration information.
