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.

Step 2 -- Install Infinity Smart Sensor
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury
or death.
Before installing sensor, turn off all power to unit. There may
be more than 1 power disconnect.
1. Turn OFF all power to unit.
2. If an existing thermostat or sensor is being replaced:
a. Remove existing device from wall.
b. Disconnect wires from existing device, I at a time. Be care-
ful not to allow wires to fall back into wall.
c. Discard or recycle old device.
d. If 4 wires exist in wall, they may be used. If not, plan and
route wiring to connect with either the Damper Control
Module, or User Interface. Multiple Infinity Smart Sensors
may be daisy chained together, but somewhere chain nmst
connect to either Damper Control Module or the Infinity
Touch Control/Infinity User Interface wall control. (Smart
Sensor daisy chain wire linfit is 100 ft.)
Recommended connection is:
A - Green = Data A
B - Yellow = Data B
C - White = 24vac (corn)
D - Red = 24vac (hot)
NOTE: It is not mandatory that the above color code be used, but
each ABCD connection in the system MUST be wired consistently.
3. To mount Smart Sensor, remove rear mounting base. Route
wires through hole in mounting base and level base against
wall.
4. Mark wall through 2 mounting holes and drill two 3/16-in.
holes. Secure assembly to wall with 2 anchors and screws
provided, making sure all wires properly extend through
opening.
5. Adjust length and routing of thermostat wire to reach each
ternfinal entry on the connector. Strip 1/4-in. of insulation
from each wire and properly connect to A-B-C-D.
6. Push any excess wire into the wall. Seal hole in wall to pre-
vent any air leaks. Leaks can affect Smart Sensor operation.
7. Attach Infinity Smart Sensor to the mounting base by lining
up the plastic guides and gently snapping assembly togeth-
er.
ELECTRICAL OPERATION HAZARD
Failure to follow this caution may result in equipment damage
or improper operation.
Improper wiring or installation may damage the Smart Sensor.
Check to make sure wiring is correct before proceeding with
installation or turning on unit.
Step 3-- Setup and Checkout
NEW INFINITY SMART SENSOR SETUP
Upon initial power up, the Infinity Smart Sensor will need to be
properly addressed. "ZONE" will be displayed and default zone
number "2" will be shown in the temperature display. The word
"SETUP" will also appear in the lower left text area. Use the
TEMP (+/-) button to select the correct zone address number 1
through 8. If only one Damper Control Module exists, the zone
address selection will only be 1 through 4. Once the zone number
is selected, press the FAN button to store the zone address and exit
the setup menu. The Infinity Smart Sensor is ready to operate.
CHANGING ZONE ADDRESS
To change an existing zone address, enter the setup menu by
pressing the FAN button for 10 seconds until "ZONE" is
displayed. Use the TEMP (+/-) button to select the correct zone
address and then press the FAN button once to automatically save
and exit the setup menu. If no buttons are pressed for
approximately 3 nfinutes, the screen will automatically save and
exit back to a normal display.
To ensure that all changes are recognized by the main control,
perform the "Full Installation" flmction in the Installation &
Service Menu of the Infinity Touch Control after zone addresses
are changed.
BACKLIGHTING
The LCD backlighting will energize whenever a button is pressed.
The backlighting will de-energize after 10 seconds of no push
button or activity, To enable constant backlighting, press the FAN

button for 10 seconds to enter setup menu. Use the HOLD button
to toggle between "LIGHT OFF" and "LIGHT ON" which will
enable a fixed low intensity backlight. Press the FAN button to
save all settings and exit the setup menu. If no buttons are pressed
for approximately 3 minutes, the screen will automatically save and
exit back to a normal display.

When used with an Infinity Touch Control wall control, pressing
the FAN button momentarily will scroll through: OFF, LOW,
MED, and HIGH speed continuous fan operation. If used with an
Infinity User Interface wall control, pressing the FAN button
momentarily will scroll through: AUTO, LOW, MED, and HIGH
speed continuous fan operation. When connected to either type of
wall control, the FAN button is used to enter into the setup mode
by holding the FAN button for 10 seconds.
HUMIDITY/OAT BUTTON
Pressing the HUMIDITY/OAT button will toggle between the
Outside Temperature and Indoor Relative Humidity reading
(humidity reading at wall control). The LCD will revert back to the
outside temperature after 5seconds.
COOL/HEAT BUTTON
Use the COOL/HEAT button to change between "COOL AT" and
"HEAT AT" setpoints.
TEMPERATURE UP/DOWN BUTTON
Use the TEMP (+/-) button to change a zone temperature setpoint.
Depending on the active heating/cooling mode, the "HEAT AT" or
the "COOL AT" setpoint will appear and will increment or
decrement accordingly. If not in a "HOLD" mode, changing the
setpoint, when used with an Infinity User Interface wall control,
will cause the Override timer to be displayed (i.e. 2-hours). If used
with an Infinity Touch Control wall control, changing the setpoint
will cause a HOLD UNTIL with a default time of approximately 3
hours from the current time to be displayed. Either the Override
timer or default time can be increased or decreased by using the
TIME (+/-) button.
TIME UP/DOWN BUTTON
When used with Infinity User Interface wall control and the TIME
(+/-) button is pressed during a normal operation, "OVERRIDE"
is displayed and the Override timer is shown (default is 2-hours).
When used with an Infinity Touch Control wall control and the
TIME (+/-) button is pressed during a normal operation, pressing
the setpoint will cause a HOLD UNTIL with a default time of
approximately 3 hours from the current time to be displayed.
When used with either wall control, the Override timer or default
time can be increased or decreased by using the TIME (+/-) button.
While the timer or default time is shown, the TIME buttons can be
used to raise or lower the Override timer or the default time in
15-minute increments up to a maximum of 24 hours. If the time is
decreased to zero, the "OVERRIDE" text disappears along with the
timer or the default time will be replaced with "SCHEDULED,"
depending on the type of wall control, and the program resumes
regular operation.
NOTE: If the wall control is configured for non-programmable
operation, the Infinity Smart Sensor will ignore HOLD and
Override functions at the Smart Sensor.
HOLD BUTTON
Pressing the HOLD button momentarily will cause "HOLD" to be
displayed. The system will continue using the active (displayed)
temperature setpoints indefinitely. Pressing the HOLD button again
removes the "HOLD" text and the system resumes normal
programming schedules. When used with an Infinity User Interface
wall control, pressing the HOLD button for approximately 3
seconds will cause "UNOCCUPIED" to be displayed in the lower
