The PremierLink controller (see Fig. 40) is compatible
with Carrier Comfort Networkr(CCN) devices. This
control is designedto 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 SystemPilot (TM), Touch Pilot (TM)
and Service Tool. (Standard tier display tools Navigatort
and Scrolling Marqueeare not suitable for use with latest
PremierLinkcontroller (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--poleterminal block (TB1) loc ated 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/accessoryEconoMi$er 2 package.
Refer to Fig. 40for PremierLink connection locations.
NOTE: Refer to Form 33CS--58SI for complete
PremierLink configuration, operating sequences and
troubleshooting information. Have a copy of this manual

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).

mode. To be used with a thermostat, the PremierLink
controller must be configured to Thermostat mode. Refer
to PremierLink Configuration instructions for Operating
