T10 — REMOTE SPACE TEMPERATURE SENSOR —

Sensor T10 (part no. HH51BX006) is an accessory sensor

that is remotely mounted in the controlled space and used

for space temperature reset. The sensor should be installed

as a wall-mounted thermostat would be (in the conditioned

space where it will not be subjected to either a cooling or

heating source or direct exposure to sunlight, and 4 to 5 ft

above the ﬂoor). The push button override button is not sup-

ported by the ComfortLink™ Controls.

Space temperature sensor wires are to be connected to ter-

minals in the unit main control box. The space temperature

sensor includes a terminal block (SEN) and a RJ11 female

connector. The RJ11 connector is used to tap into the Carrier

Comfort Network (CCN) at the sensor.

To connect the space temperature sensor (Fig. 11):

1. Using a 20 AWG twisted pair conductor cable rated for

the application, connect 1 wire of the twisted pair to one

SEN terminal and connect the other wire to the other SEN

terminal located under the cover of the space temperature

sensor.

2. Connect the other ends of the wires to terminals 5 and 6

on TB5 located in the unit control box.

Units on the CCN can be monitored from the space at the

sensor through the RJ11 connector, if desired. To wire the

RJ11 connector into the CCN (Fig. 12):

IMPORTANT: The cable selected for the RJ11 con-

nector wiring MUST be identical to the CCN commu-

nication bus wire used for the entire network. Refer to

table below for acceptable wiring.

1. Cut the CCN wire and strip ends of the red (+), white

(ground), and black (−) conductors. (If another wire color

scheme is used, strip ends of appropriate wires.)

2. Insert and secure the red (+) wire to terminal 5 of the

space temperature sensor terminal block.

3. Insert and secure the white (ground) wire to terminal 4 of

the space temperature sensor.

4. Insert and secure the black (−) wire to terminal 2 of the

space temperature sensor.

5. Connect the other end of the communication bus cable to

the remainder of the CCN communication bus.
