PremierLinkt (Factory- -Option) —
The PremierLink controller (see Fig. 27) 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 tier 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
50TCQD unit's main control box to the right of the
Control 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 control includes the
supply- - air temperature (SAT) sensor. The outdoor air
temperature (OAT) sensor
FIOP/accessory EconoMi$ert2 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).
