PREMIERLINK™ CONTROL — The PremierLink control-
ler is compatible with Carrier Comfort Network® (CCN) de-
vices. 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™ or Scrolling
Marquee can be used with the PremierLink controller.
The PremierLink controller (see Fig. 19 and 20) requires the
use of a Carrier electronic thermostat or a CCN connection for
time broadcast to initiate its internal timeclock. This is neces-
sary for broadcast of time of day functions (occupied/ unoccu-
pied). No sensors are supplied with the field-mounted Premier-
Link control. The factory-installed PremierLink control in-
cludes only the supply-air sensor (SAT) and the outdoor air
temperature sensor (OAT) as standard. An indoor air quality
(CO
2
) sensor can be added as an option. Refer to Table 5 for
sensor usage. Refer to Fig. 21 for PremierLink controller
wiring. The PremierLink control may be mounted in the
control panel or an area below the control panel.
