Sensors (Optional):
33ZCSENCO2 --- Room sensor (adjustable). Aspirator box is required for duct mounting of the sensor.

room sensor with override.
33ZCT56CO2 --- Space temperature and CO

room sensor with override and setpoint.
Outdoor Air Temperature (OAT) Sensor — The OAT is
factory--mounted in the EconoMi$er2 (FIOP or
accessory). It is a nominal 10k ohm thermistor attached to
an eyelet mounting ring.
EconoMi$er2 — The PremierLink control is used with
EconoMi$er2 (option or accessory) for outdoor air
management. The damper position is controlled directly
by the PremierLink control; EconoMi$er2 has no internal
logic device.
Outdoor air management functions can be enhanced with
field--installation of these accessory control devices:
Enthalpy control (outdoor air or differential sensors)
Space CO

sensor
Outdoor air CO

Refer to Table 4 for accessory part numbers.
Field connections — Field connections for accessory
sensor and input devices are made at the 16--pole terminal
block (TB1) located on the control box top in front of the
PremierLink control (See Fig. 26). Some input devices
also require a 24--vac signal source; connect at CTB
terminal R at “THERMOSTAT” connection strip for this
signal source. See connections figures on following pages
for field connection locations (and for continued
connections at the PremierLink board inputs).
Table 5 provides a summary of field connections for units
equipped with Space Sensor. Table 6 provides a summary
of field connections for units equipped with Space
Thermostat.
Space Sensors -- The PremierLink controller is
factory--shipped configured for Space Sensor Mode. A
Carrier T--55 or T--56 space sensor must be used. T--55
space temperature sensor provides a signal of space
temperature to the PremierLink control. T--56 provides
same space temperature signal plus it allows for
adjustment of space temperature setpoints from the face of
the sensor by the occupants.
