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 supported 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 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 con-
nect 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 connec-
tor wiring MUST be identical to the CCN communica-
tion bus wire used for the entire network. Refer to table
below for acceptable wiring.
