INTRODUCTION
Carrier’s Infinity
r
Smart Sensors are optional replacements for
Remote Room Sensors used with Infinity
r
Zoning systems. It
provides a temperature display and buttons to adjust the desired
temperature within the zone. It also displays outdoor temperature
and indoor humidity. When used with an Infinity
r
Touch Control
wall control-- FAN, HOLD and HOLD UNTIL features are
available. When used with an Infinity
r
User Interface (UIZ) wall
control-- FAN, HOLD, OVERRIDE, UNOCCUPIED features are
available.
INSTALLATION CONSIDERATIONS
Any zone may use an Infinity Smart Sensor. The Infinity Smart
Sensor can be “home run” wired directly to the Damper Control
Module, or “daisy chained” from the wall control or another Smart
Sensor via 4--wire ABCD communication bus. Ordinary thermostat
wire is recommended; however, solid conductor, stranded, or
shielded wire may be used. Use 22 AWG or larger for normal
wiring applications. Continuous wire lengths over 100 ft. should
use 20 AWG or larger. Plan the connection of each Smart Sensor to
provide easiest wiring route.
NOTE
: Whenever possible, it is suggested to always “home run”
wires back to the Damper Control Module for convenience of
troubleshooting. Using a “pig--tailed” connection, or a field
supplied terminal block may be helpful in achieving proper wire
termination at the Damper Control Module.
An Infinity Smart Sensor may now be used to control Zone 1. In
addition, a Remote Room Sensor may also be used in the same
zone. If a Remote Room Sensor is applied in the same zone, the
Remote Room Sensor has temperature priority over the Smart
Sensor.

INSTALLATION
Step 1 — Select Smart Sensor Location
Sensor should be mounted:
S
Approximately 5 ft. (1.5m) from floor.
S
Close to center of zone, preferably on inside partitioning wall.
S
On section of wall without pipes or ductwork.
S
Where wiring can be routed to it within wall. Avoid running
directly next to other AC power.
Sensor should
NOT
be mounted:
S
Close to a window, on outside wall, or next to a door leading to
the outside.
S
Exposed to direct light and heat from a lamp, sun, fireplace, or
other temperature radiating object which may cause a false
reading.
S
Close to or in direct airflow from supply registers and return--air
grilles.
S
In areas with poor air circulation, such as behind a door or in an
alcove.
S
Do not run wires next to AC power lines.
