INTRODUCTION
Carrier's
Infinity ® Smart
Sensors
are optional
replacements
for
Remote
Room
Sensors
used with
Infinity ® 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 ® Touch Control
wall
control-
FAN,
HOLD
and
HOLD
UNTIL
features
are
available.
When
used with an Infinity ® 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:
• Approximately
5 ft. (1.5m) from floor.
• Close to center of zone, preferably
on inside partitioning
wall.
• On section of wall without
pipes or ductwork.
• Where
wiring
can be routed
to it within
wall.
Avoid
running
directly
next to other AC power.
Sensor should
NOT be mounted:
• Close to a window,
on outside
wall, or next to a door leading
to
the outside.
• Exposed
to direct light and heat from
a lamp, sun, fireplace,
or
other
temperature
radiating
object
which
may
cause
a false
reading.
• Close to or in direct airflow from supply
registers
and return-air
grilles.
• In areas with poor air circulation,
such as behind
a door or in an
alcove.
• Do not run wires next to AC power
lines.
