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.
