SAFETY CONSIDERATIONS
Improper installation, adjustment, alteration, service, maintenance,
or use can cause explosion, fire, electrical shock, or other
conditions which may cause death, personal injury or property
damage. Consult a qualified installer, service agency or your
distributor or branch for information or assistance. The qualified
installer or agency must use factory--authorized kits or accessories
when modifying this product. Refer to the individual instructions
packaged with the kits or accessories when installing.
Follow all safety codes. Wear safety glasses, protective clothing,
and work gloves. Have a fire extinguisher available. Read these
instructions thoroughly and follow all warnings and cautions
included in literature and attached to the unit. Consult local
building codes and the current edition of the National Electrical
Code (NEC) NFPA 70.
In Canada, refer to the current editions of the Canadian Electrical
Code CSA C22.1.
Recognize safety information. When you see this symbol on
the unit and in instructions or manuals, be alert to the potential for
personal injury. Understand the signal words DANGER,
WARNING,andCAUTION. These words are used with the
safety--alert symbol. DANGER identifies the most serious hazards,
which will result in severe personal injury or death. WARNING
signifies hazards, which could result in personal injury or death.
CAUTION is used to identify unsafe practices, which may result
in minor personal injury or product and property damage. NOTE
is used to highlight suggestions which will result in enhanced
installation, reliability, or operation.
INSTALLATION CONSIDERATIONS
Before the actual installation of a System Access Module (SAM01)
can begin, determine the mounting location. For previous
generation UID/UIZ systems, only, a radio test must be performed
with the System Access Module in the intended mounting location.
See Step 4 to perform a radio test.
The System Access Module is powered with an independent 24
VAC, 40 VA transformer. An accessory plug--in transformer is
available to order through Replacement Components (Part No.
SYSTXNNXFM01). When using an accessory, plug--in
transformer, a 120VAC supply must be near the mounting location
of the System Access Module. Provisions must be made to secure
the transformer to the outlet, due to its weight. The D--wire (24
VAC) from the Infinity system MUST NOT be used to power the
System Access Module.
Use this instruction to guide the actual installation process after the
Infinity system(s) have been installed. One SAM01 System Access
Module is capable of handling two Infinity systems.

INTRODUCTION
The SAM01 is used differently for previous generation Infinity
systems using the UID/UIZ wall controls, versus the newer
InfinityTouch systems.
For previous generation systems using the UID/UIZ wall
controls, the SAM01 connects to the SkyTel/American Messaging
wireless paging network and allows remote connectivity for up to
two Infinity systems within the same building. The Infinity system
owner as well as authorized dealer can monitor and control the
system via the Internet.
The coverage area available to applications using the SAM01for
remote access is limited, since the System Access Module
communicates through a two--way radio via the Skytel paging
network. To check coverage, please visit:
http://www.skytel.com/coverage/telemetry_coverage.htm for the
particular installation site. The coverage must be listed as “Full
Service” for the System Access Module to function properly.
Please note that Skytel is continuously changing their service area
so coverage may not be indicated by the web site for a particular
area, or coverage may be discontinued at a later date.
The SAM01 also provides an interface to Home Automation
systems, utilizing the RS--232 serial port connection.
The newer Infinity Touch systems, with version 08 or later
software, utilize the SAM01 for ONLY interface to Home
Automation systems, utilizing the RS--232 serial port connection.
Use the Wi--Fi versions of the Infinity Touch wall controls when
connection to the Internet is desired.
For all systems, the System Access Module can also monitor a
dry--contact sensor to provide a warning for the presence of water
in the building, or some other use. If the sensor is active, the
Infinity system will not be disabled or shut down.
Compatible Systems
The SAM01 is designed for previous generation UID/UIZ wall
controls with version 12 or earlier software. When used with
version 13, or later, UID/UIZ wall controls, or with the newer
generation InfinityTouch (with version 08 software or later)
certain features, such as the “Off” mode command, will not work
properly. See the latest version of the SAM Remote Access
Application Specification, available on HVACpartners, for more
information.
NOTE:The SAM01 is designed for operation with the previous
generation UID/UIZ wall control systems. As such, it will operate
“as-is” with the newer Infinity Touch systems, and may display
status codes that are unique to the previous generation UID/UIZ
systems, but are irrelevant when the SAM01 is used with the
newer Infinity Touch systems. In addition, some features of the
RS-232/ASCII home automation interface will NOT be available
with the newer Infinity Touch systems. See the latest version of
the SAM Remote Access Interface Specification, available on
HVACpartners, for more details on the home automation
interface.
Computer Requirements (Previous generation UID/UIZ
systems, only)
The SAM01 uses a web--based application to control and monitor
the Infinity system. This application
(www.MyInfinity.Carrier.com) will work with any graphic user
interface PC operating system (Microsoft, Apple, Linux). The
web----based application is optimized for use with Microsoft’s
Internet Explorer version 6 and above. Other web browsers are
compatible with some possible screen formatting issues.
NOTE: This web--based application for the SAM01 is NOT
available for Infinity Touch systems. When using these systems,
Internet access is achieved using the Wi--Fi version of the Infinity
Touch control, and accessing the www.MyInfinityTouch.com
website.
The SAM01 is designed for previous generation UID/UIZ wall
controls with version 12 or earlier software. When used with
version 13, or later, UID/UIZ wall controls, or with the newer
generation InfinityTouch, certain features, such as the “Off”
mode command, will not work properly. See the latest version of
the SAM Remote Access Application Specification, available on
HVACpartners, for more information.
INSTALLATION
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
Considerations
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury,
death or possible equipment damage.
Disconnect supply power before routing wire.
!WARNING
NOTE: All wiring must comply with national, state, and local
codes.
LOCATING SYSTEM ACCESS MODULE
When possible, select a location near the Infinity furnace or fan coil
for the SAM01 where wiring from the User Interface, each Remote
Room Sensor or Smart Sensor, each damper actuator, and the
equipment itself can come together easily. However, if the furnace
or fan coil is located in a basement, this may not be possible due to
the strength of the radio signal from the SkyTel/American Message
transmission tower. See Step 4 for testing the radio for signal
strength. This restriction for radio signal strength does not apply
for newer Infinity Touch systems.
For previous generation UID/UIZ systems, only: Since the
System Access Module (SAM) uses two--way radio, choose a
potential mounting location that is as high and as close to outside
walls or windows as possible to attempt to maximize radio
coverage. The coverage is dependent on where the Skytel
transmission towers are located. If one location does not work, try
the opposite side of the structure to get the device in closer
directional proximity to the transmission tower. Temporarily mount
the System Access module in the intended permanent mounting
location until the radio test has passed 100%. (See Step 4.)
For all system types, the System Access Module is approved for
indoor use only and should never be installed with any of its
components exposed to the elements. The System Access Module
may be installed in any area where the temperature remains
between --4_F and 158_F(--20_C and 70_C) and 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.
The SAM should be mounted in the vertical position. Remember
that wiring access and Skytel reception are the most important
installation location considerations.
ELECTRICAL OPERATION HAZARD
Failure to follow this caution may result in equipment damage
or improper operation.
To prevent possible damage to the System access Module, do
not mount on plenum, duct work, or flush against furnace.
CAUTION
!

WIRING CONSIDERATIONS — Ordinary thermostat wire is
ideal when wiring the System Access Module (shielded cable is not
necessary). Use 22 AWG or larger for normal wiring. Lengths over
100 ft. should use 20 AWG or larger wire.
Step 3 — Connect Power Source and Antenna
UNIT OPERATION HAZARD
Failure to follow this caution may result in improper unit
operation.
Improper wiring of the ABC connector will cause the System
Access Module to operate improperly. Check to make sure all
wiring is correct before proceeding with the installation or
turning on power.
CAUTION
!
For previous generation UID/UIZ systems, ONLY, screw the
antenna to the radio connector. See Fig. 2 for antenna attachment
location.
For all systems, an independent 24 VAC, 40 VA transformer is
required to power the System Access Module. An accessory
plug--in transformer is available to order through Replacement
Components (Part No. SYSTXNNXFM01). The accessory
transformer is heavy. Make sure it is secured to the power outlet
with an appropriate screw through the base on the transformer.
DO NOT connect the D--wire (24 VAC hot) from the Infinity
system.
Step4—RadioTest
For newer generation Infinity Touch systems, the SkyTel radio is
NOT USED. Disconnect the radio module from the main SAM01
module by removing the cable between the two circuit boards. (See
Fig. 2.)
Note that none of the radio test functions will be applicable to
systems using the newer generation Infinity Touch systems,
including any error status codes that may be generated by the
system that are associated with the radio test or failures of the radio.
For previous generation UID/UIZ systems, verify that the SkyTel
radio module is connected to the main circuit board via the cable
between the main SAM01 circuit board and the radio module.
Apply power to the SAM01 in order to perform the radio test,
ONLY, at this time.
UNIT OPERATION HAZARD
Failure to follow this caution may result in improper unit
operation.
Improper wiring of the ABC connector will cause the System
Access Module to operate improperly. Check to make sure all
wiring is correct before proceeding with the installation or
turning on power.
CAUTION
!
The purpose of the radio test is to verify effective 2--way
communications at the installation site. The test must pass 100%
before the installation of the SAM can continue.
Press and hold the RADIO TEST button for at least 5 seconds. A
flashing Yellow LED will indicate the test is in progress. A flashing
Yellow and Green LED means the transmission is complete and the
System Access Module is waiting for a reply. A constant Green
LED means the radio test has passed. The radio will perform three
message tests, so this sequence will occur three times. If the System
Access Module has errors during the process, the test could take up
to 15 minutes.
If the Red LED is lit solid, then the System Access Module failed
to send the message. Try a new mounting location for the System
Access Module.
If the Yellow LED is lit solid, then the System Access Module sent
its message but did not receive a reply. The Carrier server may be
down or the received signal is weak. Try a new mounting location
for the System Access Module.
Aborting Test -- There is no method to abort a radio test once it is
started, other than to remove power.
The LEDs will maintain their state for one hour after the test.
Pressing the Radio Test button momentarily will clear the LEDs.
Pressing the Radio Test button again for five seconds will repeat
the radio test. See Fig. 3 for a description of the radio test and LED
sequence.
REMOVE POWER and continue with the installation.
Step 5 — Install Components
INSTALL SYSTEM ACCESS MODULE — Once the previous
step has been completed, the System Access Module can be
permanently installed. The System Access Module is designed so
that wires can enter it from behind, above, or below. Plan wire
routing before mounting.
1. Remove cover to access mounting holes.
2. Mount back plate to wall using screws and wall anchors
provided.
3. Level back plate and tighten screws.
Step 6 — Connect Infinity Systems
UNIT OPERATION HAZARD
Failure to follow this caution may result in improper unit
operation.
Improper wiring of the ABC connector will cause the System
Access Module to operate improperly. Check to make sure all
wiring is correct before proceeding with the installation or
turning on power.
CAUTION
!
Connect the A, B, and C wires from the Infinity system to
terminals labeled A1, B1, and C1. Connect the second Infinity
system (if present) to the terminals labeled A2, B2, and C2.
ABC bus wiring only requires a three wire connection; however, it
is good practice to run thermostat cable greater than three wires in
the event of a damaged or broken wire during the installation.
It is recommended that the following color code be used when
wiring each ABC connector:
A — Green Data A
B — Yellow Data B
C — White 24VAC (Com)
NOTE: The D--wire (red -- 24 VAC hot) from the Infinity system
is not connected to the System Access Module.
It is not mandatory that the above color code be used, but each
ABC connector in the system MUST be wired consistently.
Step 7 — Connect Auxiliary Sensor (optional)
The System Access Module will support a dry contact sensor for
use with water detection or some other use as seen fit. Connect one
side of the contacts to connector AUXC (common) and the other
side to connector AUX (input). The sensor input can provide up to
20mA at 5 volts d.c. If the sensor input is active, it will not shut
down or affect operation of the HVAC system(s). A pop--up
message will appear on the user interface indicating the auxiliary
sensor is active.
The homeowner can also be notified via email, if so chosen, by
selecting the appropriate options on the Internet website user

4
interface application. See the appropriate website user interface
application for more information:
SFor previous generation UID/UIZ systems,use
www.MyInfinity.Carrier.com.
SFor newer generation Infinity Touch systems, use
www.MyInfinityTouch.com. The Auxiliary Sensor email
alerts are enabled when the “Urgent” notifications are
enabled.
Step 8 — System Start--Up
After the previous steps have been performed, power may be
applied to the system, including both the SAM01 and the Infinity
system. The Infinity wall control will automatically find the
SAM01 at system power on during the system self--installation
sequence. If the SAM is being added to an existing system, initiate
a full system re--install sequence to ensure that the SAM is
discovered properly.
The wall control will enter the system installation screens
automatically and will display the Equipment Summary screen
when finished. For previous generation UID/UIZ systems,the
Equipment Summary screen will display REMOTE ACCESS YES
near the bottom. For the newer Infinity Touch systems,theword
SAM will appear toward the bottom right of the Equipment
Summary screen. If REMOTE ACCESS YES or SAM is not
displayed on the Equipment Summary screen, or if “no sam” is
displayed in the Infinity Touch Equipment Summary screen, check
connections to the ABC wires as well as ensure the Yellow LED is
lit on the SAM01 (this ensures the module has power). The Green
LED will be lit next to each ABC connection if the User Interface
(wall control) has established communications.
NOTE: The Yellow Status LED may begin to flash status codes
when used with newer generation Infinity Touch systems. This is
likely due to the fact that the network interface within the SAM
enclosure has been disconnected. The following status codes
should be ignored when using the SAM with newer generation
Infinity Touch controls:
Code 61: Radio out of range
Code 62: Loss of communication with radio or Ethernet device
Code 63: Radio not registered
Code 66: Ethernet/Wi-Fi not detected
Code 67: No communication with server
Step 9 — PIN Number and Serial Number (For
previous generation UID/UIZ systems, only)
The PIN and Serial number of the System Access Module are used
by the system owner to register their system with the Carrier web
server Remove the sticker containing the PIN number from the
radio and install at the front of the Owner’s Guide. Also, write
down the SAM serial number in the Home Owner’s Guide. The
serial number can be found on the SAM packaging, at the bottom
of the large SAM circuit board or in the user interface Service
Menu. If PIN number is lost or missing, it can be found by entering
the Service Menu of the User Interface (10 second press of the
Advance button) and looking at the Model/Serial Numbers screen.
The PIN will be listed with the System Access Module model and
serial numbers.
RS--232 CONNECTOR
An RS--232 port has been provided for connection to home
automation equipment. Consult your home automation supplier for
support. If the particular home automation supplier needs
information for the interface, you may supply the latest version of
the SAM Remote Access Interface Specification, found on
HVACpartners, to the home automation supplier. Designing and
providing the interface to the Infinity system through the RS--232
communication port on the SAM is the responsibility of the home
automation supplier. Contact your Distributor Service Manager for
details, if required.
UPDATING SYSTEM PROFILE
(For previous generation UID/UIZ systems, only)
The Infinity System will automatically send system information to
Carrier’s computer servers within one hour after the system has
been successfully installed. Access to the system via the Internet or
telephone will not be available until this occurs. The system can be
forced to send its information through the following process if
Internet and telephone access is required immediately. Press and
hold the RADIO TEST button for 15 seconds. When the button is
first pressed, the Red LED will turn on. Five seconds into the press,
the Yellow LED will turn on. Fifteen seconds into the press, the
Green COM1 LED will turn on. Release the button when the
Green LED turns on. The Red LED will flash when messages are
being sent. The Red and Yellow LEDs will flash when the SAM is
waiting for message replies. Upon successful profiling, both Green
LEDs will be lit. If profiling is not successful, the Red LED will be
lit solid. The entire profiling process can take up to 15 minutes per
Infinity System. If two systems are connected to one SAM, then
the profiling process can take up to 30 minutes.
If the Infinity system ABC wiring is moved from connector 1 to
connector 2 (or vice versa), or Infinity equipment has changed, the
System Access Module must update Carrier’s servers with the new
information. This will happen automatically within one hour, or
can be manually forced with the process described above.
TROUBLESHOOTING
FAULT INDICATORS — Under normal operation, the Yellow
and Green LED will be on continuously (solid). If the System
Access Module does not receive communications with the Infinity
system, the Green LED will not be on. If there are faults present,
the Yellow LED indicator will blink a two digit status code. The
first digit will blink at a fast rate, the second at a slow rate.
NOTE:When the SAM01 is used with the newer Infinity Touch
systems, it may display status codes that are unique to the
previous generation UID/UIZ systems, but are irrelevant when
the SAM is used with the newer Infinity Touch systems. See the
note below for these codes that should be ignored.
