Outdoor Air Temperature (OAT) Sensor —
The OAT is factory--mounted in the EconoMi$er R 2 (FIOP
or accessory). It is a nominal 10k ohm thermistor attached
to an eyelet mounting ring.
EconoMi$er2 —
The PremierLink
t
controller is used with EconoMi$er2
(option or accessory) for outdoor air management. The
damper position is controlled directly by the PremierLink
controller; the EconoMi$er2 unit 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

Refer to Table 22 on page 45 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 bottom shelf in front of the PremierLink
controller (see Fig. 50). 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 23 (on page 46) provides a summary of field
connections for units equipped with Space Sensor. Table 24
(on page 46) 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
controller. 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.

Connect Thermostat —
A 7--wire thermostat connection requires a 24--v power
source and a common connection. Use the R and C
terminals on the CTB’s THERMOSTAT connection strip
for these. Connect the thermostat’s Y1, Y2, W1, W2 and
G terminals to the PremierLink controller at TB1 as
shown in Fig. 55.
If the 50TCQ unit is equipped with factory--installed smoke
detector(s), disconnect the factory BLU lead at TB1--6 (Y2)
before connecting the thermostat. Identify the BLU lead
originating at CTB--DDC--1; disconnect at TB1--6 and tape
off. Confirm that the second BLU lead at TB1--6 remains
connected to the PremierLink controller at J4--8.
