PREMIERLINKT CONTROL
The PremierLink controller (see Fig. 33) is compatible
with Carrier Comfort Networkr (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 t ier display tools Navigatort
and Scrolling Marquee are not suitable for use with latest
PremierLink controller (Version 2.x).)
The PremierLink control is factory--mounted in the 50TC
unit’s main control box to the left of the LCTB. Factory
wiring is completed through harnesses connected to t he
LVTB. 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 controlle r The
factory-- installed PremierLink control includes the
supply--air te mperature (SAT) sensor. The outdoor air
temperature (OAT) sensor is included in the
FIOP/accessory Economizer 2 package.
Refer to Fig. 33 for PremierLink connection locations.
NOTE: Refer to 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 shippe d 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.
Supply Air Temperature (SAT) Sensor — On
FIOP--equipped 50TC unit, the unit is supplied with a
supply--air tem perature (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 installat ion.
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. 36.
