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).

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 con-

nector. The RJ11 connector is used to tap into the Carrier Com-

fort Network (CCN) at the sensor.

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

1. Using a 20 AWG (American Wire Gage) 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):

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.

IMPORTANT: The cable selected for the RJ11 connector

wiring MUST be identical to the CCN communication bus

wire used for the entire network. Refer to table below for

acceptable wiring.
