Field-Installed Accessories

Space Temperature Sensor (T−55)
The T-55 space temperature sensor (part no. 33ZCT55SPT) is a
field-installed accessory. The sensor is installed on a building
interior wall to measure room air temperature. The T-55 sensor also
includes an override button on the front cover to permit occupants
to override the Unoccupied Schedule (if programmed). The jumper
wire in the installer's packet must be connected between R and W1
when using a T-55 device.

Space Temperature Sensor (T−56)
The T-56 space temperature sensor (part no. 33ZCT56SPT) is a
field-installed accessory. This sensor includes a sliding scale on the
front cover that permits an occupant to adjust the space temperature
set point remotely. The T-56 sensor also includes an override
button on the front cover to allow occupants to override the
unoccupied schedule (if programmed). The jumper wire in the
installer's packet must be connected between R and W1 when
using a T-56 device.

Space Temperature Sensor (T−58)
The T-58 space temperature sensor (part no. 33ZCT58SPT) is a
field-installed accessory. The T-58 sensor communicates with the
ComfortLink controller, providing space temperature, heating
and cooling set points, and mode operation information. The
jumper wire in the installer's packet must be connected between R
and W1 when using a T-58 device.
Refer to the T-58 installation instructions for information on
installing and configuring the T-58 sensor.
Each T-58 sensor must have a unique address on the CCN. Each
T-58 sensor must also be configured with the address of the unit
control it is communicating to.
Space Temperature Sensor Averaging
See Fig. 47 for space temperature averaging with T-55 sensors
only. If the use of one T-56 sensor is required, refer to Fig. 48.
