Outdoor Air Temperature (OAT) Sensor — The OAT is
factory--mounted in the EconoMi$er2 (FIOP or
accessory).It is a nominal 10k ohm thermistor attached to
an eyelet mountingring.
EconoMi$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--installationof these accessory controldevices:
Enthalpy control (outdoor air or differential sensors)
Space CO2sensor
Outdoor air CO2sensor
Refer to Table3 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 control (See Fig. 30). 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 4 provides a summary of field connections for units
equipped with Space Sensor. Table 5 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.

Connect Thermostat — A 7--wire thermostat connection
requires a 24--vpower 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 PremierLink TB1 as
shown in Fig. 35.
If the 50TCQ unit is equipped with factory--installed
smoke detector(s), disconnect the factory BLU lead at
TB1--6(Y2) before connecting the thermosta t. Identify the
BLU lead originating at CTB--DDC--1; disconnect at
TB1--6and tape off. Confirm that the second BLU lead at
TB1--6remains connected to PremierLink J4--8.
