Fig. 48 -- PremierLink Controller
The PremierLink controller (see Fig. 48) 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
t
, Touch Pilot
t
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 controller is factory--mounted in the
50TCQ unit’s main control box to the left of the Central
Terminal Board (CTB). Factory wiring is completed
through harnesses connected to the CTB 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 controller includes the supply--air temperature
(SAT) sensor. The outdoor air temperature (OAT) sensor is
included in the FIOP/accessory EconoMi$er
R
2 package.
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 the PremierLink Controller Installation, Start--up, and
Configuration Instructions for Operating Mode.
Supply Air Temperature (SAT) Sensor —
Units with a factory--installed PremierLink controller include
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.
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. 49.

NOTE
: Refer to the PremierLink Controller Installation,
Start--up, and Configuration Instructions for complete
PremierLink controller configuration, operating sequences
and troubleshooting information. Have a copy of this
manual available at unit start--up.
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’s heater surfaces.
