NOTE: PremierLink™ controller versions 1.3 and later are
shipped in Sensor mode. If used with a thermostat, the Pre-
mierLink controller must be configured to Thermostat mode.
Install the Supply Air Temperature (SAT) Sensor — When
the unit is supplied with a factory-mounted PremierLink con-
trol, the supply-air temperature (SAT) sensor (33ZCSENSAT)
is factory-supplied and wired. The wiring is routed from the
PremierLink control over the control box, through a grommet,
into the fan section, down along the back side of the fan, and
along the fan deck over to the supply-air opening.
The SAT probe is wire-tied to the supply-air opening (on the
horizontal opening end) in its shipping position. Remove the
sensor for installation. Re-position the sensor in the flange of
the supply-air opening or in the supply air duct (as required by
local codes). Drill or punch a
1
/
2
-in. hole in the flange or duct.
Use two field-supplied, self-drilling screws to secure the sensor
probe in a horizontal orientation.
NOTE: The sensor must be mounted in the discharge airstream
downstream of the cooling coil and any heating devices. Be
sure the probe tip does not come in contact with any of the unit
or heat surfaces.
Outdoor Air Temperature (OAT) Sensor — When the unit is
supplied with a factory-mounted PremierLink control, the
outdoor-air temperature (OAT) sensor is factory-supplied and
wired.
Install the Indoor Air Quality (CO
2
) Sensor — Mount the
optional indoor air quality (CO
2
) sensor according to manufac-
turer specifications.
A separate field-supplied transformer must be used to pow-
er the CO
2
sensor.
Wire the CO
2
sensor to the COM and IAQI terminals of J5
on the PremierLink controller. Refer to the PremierLink Instal-
lation, Start-up, and Configuration Instructions for detailed
wiring and configuration information.
