1. Introduction
CONGRATULATIONS! Your decision to choose the Infinity System puts you in a select
group of homeowners who understand the value of precise comfort control and appreciate the
simplicity of an easy-to-use, intuitive, Control.
Your new Infinity System offers high quality comfort technology. Please take a few moments to
carefully read through this manual. Next set up a comfort profile and schedule that makes sense
for your lifestyle; then relax and enjoy the new comfort of your home!
2. Home Screen
2.1. Information Displayed
NOTE: When you connect your system to the Internet and register on the My Infinity website,
you can access nearly all of the consumer features on the Carrier® Home mobile app. See the
WIRELESS section for more information.
The information displayed on the Home Screen will appear when there has been no interaction
with the Infinity System Control for at least two minutes. The basic information displayed on
the Home Screen consists of the current date and time, the room temperature (zone temperature
if applicable), the outdoor temperature (if available, contact your installing dealer for details),
occupancy sensing status and current weather condition. (Wi-Fi® models only, when properly
configured). Connectivity status to the home Wi-Fi network and the MyInfinity Server will also
be displayed on the Home Screen. Note: You must have Wi-Fi enabled for the indicator to
appear.
If you have uploaded a photo to the Control (see page 40), it will be displayed until you touch
the display. You will then be taken to the Home Screen.
2.2. Occupancy Status
When the occupancy sensing feature is enabled, a dot (occupancy sensing indicator) next to the
zone name is shown to indicate if the room is sensed to be occupied. When no movement is
detected, Occupancy Status indicator stays GRAY. When movement is detected, but the system
hasn’t yet determined that the space is occupied (example, someone is just walking through the
room), Occupancy Status indicator turns BLUE. When the system determines that the space is
occupied, Occupancy Status indicator turns GREEN.

2.3. Wi-Fi® Connectivity Status
A13258C
Connectivity status to the home Wi-Fi network and MyInfinity Server is displayed in the top
right hand corner of the Home Screen.
Infinity System Control is connected to the home Wi-Fi network and the MyInfinity Server, the
signal strength bars will be displayed in white as depicted in the image below. Connection
strength to the home Wi-Fi network will be indicated by the number of solid white bars
displayed. A red “X” over the bars indicates no connection to the home Wi-Fi network.

• Pressing on the Connectivity Status bars from the Home Screen will allow you to view the
Remote Access Status screen.
Strong Connection Limited Connection Poor Connection No Connection

NOTE: If the Infinity System Control is not connected to the home network, a red “X” will
appear over the strength bars. If the Infinity System Control is connected to the home Wi-Fi
network but loses connection to the MyInfinity Server, a triangle will appear over the strength
bars as depicted in the image below. Connection strength to the home Wi-Fi network will
continue to be displayed by the number of solid bars. If this problem persists, please contact
1-800-Carrier for assistance.

2.4. Information Buttons
On the bottom of some screens will be an information icon. By pressing the information icon, a
text box will display to show what interactions are available on that particular screen. To close
the text box, touch the text box.
A14237C
3. Main Screen
The Main Screen is where most interactions will take place. Touch anywhere on the Home
Screen to arrive at the Main Screen. The most convenient way to interact with your control is
using the Carrier® Home mobile app. See the WIRELESS section for more details on
connecting your product to the Internet.
3.1. System Mode
Once in the Main Screen,
• To access your system mode touch the MODE label located in the upper right of the Control.
• The drop-down menu will allow you to choose between AUTO, HEAT, COOL, FAN
ONLY and OFF, depending on the equipment installed in your system.
• If OFF is selected your system will not control temperatures, humidity, or fan.
• If AUTO is selected, the Infinity System Control automatically switches between heating
and cooling to maintain your comfort during transitional seasons.
NOTE: AUTO mode is intended to switch between heating and cooling modes based on
temperature demand. A gradual auto transition is the energy-conscious default that will satisfy
the majority of customers. For Infinity Zoning systems, some customers might have significant
and simultaneous heating and cooling demands in different zones. To address this need, a
special simultaneous heating and cooling demand auto mode could be enabled by the Installer.

9
When the feature is enabled and AUTO mode is selected, the simultaneous heating and cooling
demand auto mode will alternate between heating and cooling, depending on demand, every
half hour. This may result in higher energy usage but provide the benefit of greater comfort.
Your installing contractor is able to enable this feature, if desired. (This feature is only available
with zoned systems).
• If HEAT is selected then the Infinity System Control operates only the heating system.
• If COOL is selected then the Infinity System Control operates only the cooling system.
• If FAN ONLY is selected, then the Infinity System Control operates the indoor fan but
heating, cooling, humidification or dehumidification will not take place.
3.2. Set Day and Time
• To set the day and time for your home screen enter the Main Screen by touching anywhere on
the Control.
• Touch the DAY and TIME label located at the top middle of the screen or access by going
through the menu screen (see page 32).
• To set the HOUR, MINUTE, MONTH, DAY, or YEAR touch the feature you wish to
change.
• Use the Up (Y) and Down (B) buttons to make the appropriate changes.
• When you have completed all of the settings, touch SAVE.
• If you make a mistake you may touch CANCEL and begin again.
3.3. Adjust Temperature (Temporary Hold)
The Infinity System Control allows you to temporarily override your programmed schedule by
adjusting the indoor temperature at any time to meet your needs.
NOTE: The Infinity System may seem slow to react to set point, activity and system mode
changes. This is normal, as the system will ramp up capacity and fan speeds slowly to achieve
the proper level of home conditioning, while avoiding wasting energy, stressing home circuits
and dimming lights with a ”hard start.”
3.4. Adjusting Comfort Activities (See Comfort Profiles on
page 14)
• To adjust the comfort activity, enter the Main Screen by touching anywhere on the Control.
• Touch the activity/top button under the Touch ’N’ Go® feature on the left side of the screen;
then select the desired activity of HOME, AWAY, SLEEP, or WAKE.
• Use the Up (Y) and Down (B) buttons to change the time to temporarily hold the desired
temperature in 15 minute increments.
• When the correct time interval is displayed, touch DONE.
• To return to the scheduled program, touch HOLD UNTIL, and then select PER
SCHEDULE.

3.5. Adjusting Heating
NOTE: If OFF is selected, the Heat, Cool, Auto and Fan Only will not be available. When
changing from the OFF mode to Heat, Cool, Auto, or Fan Only, it is normal for the system to
run the blower for a minute or two. During this time, the system is using the True Sense™
feature to determine the filter usage. This feature is part of the system design and cannot be
turned off.
• To adjust the heating temperature, enter the Main Screen by touching anywhere on the
Control.
• With the system in either AUTO or HEAT mode, use the Up (Y) and Down (B) buttons to
set the desired temperature.
• On the left hand side of the screen, the comfort profile will switch to manual, and the system
will be placed in a temporary hold.
• Use the Up (Y) and Down (B) buttons to change the time to temporarily hold the desired
temperature in 15 minute increments.
• When the correct time interval is displayed, touch DONE.
• To return to the scheduled program, touch HOLD UNTIL, and then select PER
SCHEDULE.
3.6. Adjusting Cooling
• To adjust the cooling temperature, enter the Main Screen by touching anywhere on the
Control.
• With the system in either AUTO or COOL mode, use the Up (Y) and Down (B) buttons to
set the desired temperature.
• On the left hand side of the screen, the comfort profile will switch to manual, and the system
will be placed in a temporary hold.
• Use the Up (Y) and Down (B) buttons to change the time to temporarily hold the desired
temperature in 15 minute increments.
• When the correct time interval is displayed, touch DONE.
