Fig. 36 -- PremierLink Controller
The PremierLink controller (see Fig. 36) 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 Pilott, Touch Pilott 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 48HC
unit’s main control box to the right of the Central Terminal
Board (CTB) (see Fig. 37). Factory wiring is completed
through harnesses connected to the CTB thermostat. Field
connections are made at a 16--pole terminal block (TB3)
located at the top 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$ert2 package. (See page 45 for
accessory enthalpy controls.)
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.
