PremierLink™ Controller (Factory Option)
The PremierLink controller (see Fig. 42) is compatible with
Carrier Comfort Network
®
(CCN) devices. This control is de-
signed 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, Touch Pilot and Service Tool. (Standard tier display tools
Navigator and Scrolling Marquee are not suitable for use with
latest PremierLink controller (Version 2.x).
The PremierLink controller is factory-mounted in the 50TC
unit's main control box to the left of the Central 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 controller includes the sup-
ply-air temperature (SAT) sensor. The outdoor air temperature
(OAT) sensor is included in the FIOP/accessory EconoMi$er 2
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 Premier-
Link Configuration instructions for Operating Mode.
