Carrier 50TC*D17 Series Installation Instructions Manual page 17

PremierLinkt (Factory- -Option) —
The PremierLink controller (see Fig. 24) 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
50TC*D unit's main control box to the right of the Central
Terminal Board (CTB). Factory wiring is completed
through harnesses connected to the CTB pin connectors.
Field connections are made at a 16- - pole terminal block
(TB1) located at the top of the unit control box, directly
over the top section of the PremierLink controller (see
Fig. 21). 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.
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.
