Carrier SYSTXCC4ZC01 Air Conditioner User Manual

Zoning User Interface (p/n SYSTXCCUIZ01) Each instal-
lation has only 1 User Interface. This is the command center for
the entire system. It will typically be located in Zone 1 to sense
and control the temperature in this zone. If desired, a Remote
Room Sensor or a Smart Sensor may be used to sense the Zone
1 temperature. This can give the installer some flexibility in
locating the User Interface to another area.
Remote Room Sensor (p/n SYSTXCCRRS01) Any zone
may use a Remote Room Sensor (including Zone 1). This is a
temperature sensor only, having no additional user inputs. In
applications where zone temperature averaging may be desired,
this may be done using 4 Remote Room Sensors in a series /
parallel wiring configuration (See Fig. 11 for Remote Room
Sensor Averaging).
Smart Sensor (p/n SYSTXCCSMS01) Any zone may use a
Smart Sensor (including Zone 1). It provides a temperature
display and buttons to adjust the desired temperature in that
zone only. It also displays the outdoor temperature and indoor
Be sure to select the desired sensor type for each zone. Zone
sensors other than the User Interface must be purchased separately.
Installation Instructions for these sensors are included with them.
Step 1—Check Equipment and Job Site
INSPECT EQUIPMENT File claim with shipping company,
prior to installation, if shipment is damaged or incomplete.
Step 2—Component Location and Wiring Consider-
Failure to follow this warning could result in personal injury
or possible equipment damage.
Disconnect supply power before routing wire.
NOTE: All wiring must comply with national, local, and state
All system wiring is run back to the Infinity Damper Control.
Select a location near the Infinity furnace or fan coil where wiring
from the User Interface, each Remote Room Sensor or Smart
Sensor, each damper actuator, and the equipment itself can come
together easily.
The Infinity Damper Control is approved for indoor use only and
should never be installed with any of its components exposed to
the elements. The Infinity Damper Control (and the zone dampers)
may be installed in any area where the temperature remains
between -4° F. to 158° F. (-20° Cto70° C), and where there is no
condensation. The cover must be installed to prevent damage from
other sources. Do not locate where it will be accessible to children.
It may be mounted in either vertical or horizontal position.
Remember that wiring access is likely the most important consid-
Failure to follow this caution will result in equipment damage
or improper operation.
To prevent possible damage to the Infinity Damper Control,
do not mount on plenum, duct work, or flush against furnace.
face is the command center for the Infinity Zone System. It should
be located where it is easily accessible and visible to home or
business owner. It is also normally the Zone 1 sensor and as such
needs to be located to properly measure the temperature in Zone 1.
If these two requirements conflict, a separate Remote Room
Sensor can be added for Zone 1.
When a Remote Room Sensor is connected to Zone 1 termi-
nals(ZS1 and ZS1C) of the Infinity Damper Control, the system
automatically switches to using this sensor for Zone 1 and ignores
the sensor within the User Interface. This arrangement allows the
User Interface to be located at any convenient place within the
home or business. In this arrangement, only the Zone 1 Remote
Room Sensor must be located in Zone 1.
NOTE: The User Interface also controls humidity functions. If
the User Interface is not used to control Zone 1 temperature, it
must still be located in a suitable area where humidity control will
not be affected.
LOCATING SENSORS For proper operation, each sensor
must accurately measure the temperature within its zone. For
accurate temperature measurement, the following guidelines
should be followed:
Sensor should be mounted:
Approximately 5 ft. (1.5m) from floor.
Close to the center of its zone, preferably on an inside wall.
On a section of wall without pipes or ductwork.
Sensor should NOT be mounted:
Close to a window, on an outside wall, or next to a door leading
to the outside.
Where it will be 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.
In areas with poor air circulation, such as behind a door or in
an alcove.
WIRING CONSIDERATIONS Ordinary thermostat wire is
ideal when wiring the Infinity Zoning System (shielded cable is
not necessary). Use 22 AWG or larger for typical installations.
Lengths over 100 ft. should use 20 AWG or larger wire. Remote
Room Sensors require only 2 conductors, but it is recommended
that at least 4 conductors be run. This will allow a Smart Sensor to
replace the Remote Room Sensor with no wiring changes at a later
date. The User Interface requires 4 conductors, each damper
actuator requires 3 conductors. Cut off or fold back and tape any
unneeded wires. Plan the routing of wiring early to avoid possible
problems later. Remember, all wires converge at the Infinity
Damper Control, so its location is important.
NOTE: Wiring of the ABCD bus only requires a four wire
connection; however, it is good practice to run thermostat cable
having more than four wires in the event of a damaged or broken
wire during installation.
The following color code is recommended for each ABCD bus
A Green = Data A
B Yellow = Data B
C White = 24 VAC (Com)
D Red = 24VAC (Hot)
It is not mandatory that the above color code be used, but each bus
connection in the system MUST be wired consistently.
