PREMIERLINK
t
CONTROL
The PremierLink controller (see Fig. 41) is compatible
with Carrier Comfort Network
r
(CCN) devices. 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. CCN service
access tools include System Pilot (TM), Touch Pilot (TM)
and Service Tool. (Standard tier display tools Navigator
t
and Scrolling Marquee are not suitable for use with latest
PremierLink controller (Version 2.x).)
The PremierLink control is factory--mounted in the 48TC
unit’s main control box to the left of the LCTB. Factory
wiring is completed through harnesses connected to the
LCTB thermostat. Field connections are made at a
16--pole terminal block (TB1) located on the bottom shelf
of the unit control box in front of the PremierLink
controller The factory--installed PremierLink control
includes the supply--air temperature (SAT) sensor. The
outdoor air temperature (OAT) sensor is included in the
FIOP/accessory EconoMi$er 2 package.
Refer to Fig. 41 for PremierLink connection locations.
NOTE
: Refer to the Rooftop PremierLink Installation,
Start-Up,
and
Configuration
Instructions
(Form
33CS--58SI) for complete PremierLink configuration,
operating sequences and troubleshooting information.
Have a copy of this manual available at unit start--up.
The PremierLink controller 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).
NOTE
:
PremierLink controller is shipped in Sensor
mode. To be used with a thermostat, the PremierLink
controller must be configured to Thermostat mode. Refer
to PremierLink Configuration instructions for Operating
Mode.

Sensor
—
On
FIOP--equipped 48TC unit, the unit is supplied with a
supply--air temperature (SAT) sensor (33ZCSENSAT).
This sensor is a tubular probe type, approx. 6--inches (12.7
mm) in length. It is a nominal 10--k ohm thermistor. See
Table 15 for temperature--resistance characteristic.
The SAT is factory--wired. 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. (See Fig. 42.)
