Premierlink Sensor Usage - Carrier 50TC Installation Instructions Manual

Outdoor Air Temperature (OAT) Sensor — The OAT is
factory- - mounted in the
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 sensor

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 bottom shelf in
or front of the PremierLink control (See Fig. 29). 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
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.
