PREMIERLINK™ CONTROL — The PremierLink control-
ler is available as a special order from the factory and is com-
patible with the Carrier Comfort Network® (CCN) system.
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. Carrier's diagnostic standard
tier display tools such as Navigator™ device or Scrolling
Marquee can be used with the PremierLink controller.
The PremierLink controller (see Fig. 20) 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). No
sensors are supplied with the field-mounted PremierLink con-
trol. The factory-installed PremierLink control includes only
the supply-air temperature (SAT) sensor and the outdoor air
temperature (OAT) sensor as standard. An indoor air quality
(CO ) sensor can be added as an option. Refer to Table 4 for

sensor usage. Refer to Fig. 21 for PremierLink controller wir-
ing. The PremierLink control may be mounted in the control
panel or an area below the control panel.
NOTE: PremierLink controller version 1.3 and later is shipped
in Sensor mode. If used with a thermostat, the PremierLink
controller must be configured to Thermostat mode.

unit is supplied with a factory-mounted PremierLink control,
the supply-air temperature (SAT) sensor (33ZCSENSAT) is
