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!

Home Screen

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 55), it will be displayed until you touch the display. You will then be taken to the Home Screen.

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.

Wi-Fi® Connectivity Status

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.
• 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.
• Pressing on the Connectivity Status bars from the Home Screen will allow you to view the Remote Access Status screen.

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.

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.

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. 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.

Utility Demand Event Response Setup

This section is only applicable if your utility company is running a demand response or price response program in which you have agreed to participate. Contact your local electrical utility company for information about programs in your area.
NOTE: If you wish to participate with your electrical utility company, a service person or Utility representative must enable the utility event interface.

Utility Event
Your utility may send price response or demand response events to your Wi-Fi connected Infinity System Control. When a price response or demand response event is received, your temperature set points will be automatically adjusted depending on the utility event setup settings that you have selected.

When a utility event is in progress…

• The temperature set points will be automatically adjusted depending on the utility event setup. The adjusted heating and cooling temperatures will be displayed in green on the Main Screen along with a “utility event” message.
• A utility event icon will appear on the home screen. Pressing the icon or manually adjusting the heating and cooling set points will display.
• Pressing the accept button will accept the adjustments made to the heating and cooling set points.
• Pressing the override button will change the heating and cooling set points back to their original values prior to the event.

NOTE: If you change the set points, or reject participating in a particular response event, your utility may not provide the credit or other compensation that is part of that program.

Price Response
Price response determines how the heating and cooling set points will be adjusted during a pricing event with two choices – offsets or absolute temperature. When offsets are selected, the heating and cooling set points are adjusted by the number of degrees selected. When absolute temperature is selected, the heating and cooling set points are adjusted to heating and cooling temperatures.

Price Settings
When the electric rate from the utility company meets or exceeds the “ELECTRICAL RATE”, the heating and cooling set points will be adjusted according to the absolute temperature or offset shown here. If the set point at the time of the event is more favorable (uses less energy) than what you have programmed, the Infinity System Control will use the more favorable set point for the duration of the event. Unless otherwise indicated, all settings temperatures will be shown in Fahrenheit degrees.

Demand Response
Demand response determines how the heating and cooling set points will be adjusted during a demand response event with two choices – offsets or absolute temperature. When offsets are selected, the heating and cooling set points are adjusted by the number of degrees selected. When absolute temperature is selected, the heating and cooling set points are adjusted to heating and cooling temperatures.

Demand Settings
When a demand response is received from the utility company, the heating and cooling set points will be adjusted according to the absolute temperature or offset shown here. If the set point at the time of the event is more favorable (uses less energy) than what you have programmed, the Infinity System Control will use the more favorable set point for the duration of the event.

Response Limits
Response limits are minimum heating and maximum cooling temperatures allowed during a utility event. These limits are not exceeded and are intended to protect the occupant premises from extreme temperatures that might otherwise be imposed by a utility event. Unless otherwise indicated, all settings temperatures will be shown in Fahrenheit degrees.

Restore UE Factory Default Settings
Restore UE (Utility Event) factory default settings will restore all utility event set points and price settings to their original factory default values.
