The thermostat connects to the Internet using your existing Wi-Fi® router. To set up a connection, simply navigate to the Wi-Fi menu (Main Menu > Settings > Wi-Fi > Setup a Wi-Fi connection) and follow the steps to setup your Wi-Fi connection.

Why does the system need my home address?

Outdoor weather conditions have a significant impact on your home’s energy usage. The Carrier Côr thermostat uses your home’s address to gather local weather data from the Internet so it can make smart, energy-saving decisions when managing your heating & cooling system. Without this local weather data, many of the thermostat’s smart features will be deactivated.

What if I don’t have a Wi-Fi router?

Without a Wi-Fi connection to the Internet you can still use the Côr thermostat to control your equipment, however many of Côr thermostat’s algorithms and smart features will be disabled. Your Carrier dealer can offer installation of an optional Wi-Fi router for your system.

What can I do from the web portal?

The web portal gives you access to nearly everything you have access to on the thermostat with the exception of installation settings (for safety reasons we do not allow users to change installation settings remotely).

Can I manage more than one thermostat from my account?

How do I get the most energy savings out of my thermostat?

The Côr thermostat is designed to optimize standard heating and cooling systems based on your schedule, unique characteristics of your home, and your current weather conditions. The first step in getting the most from your Côr thermostat is getting it working for you by:

  1. Registering your thermostat: The Côr thermostat relies on the Internet to get critical information such as the local weather it needs in order to run many of its advanced algorithms. Register your thermostat
  2. Setting your schedule: Set up your typical schedule and desired comfort settings for key activities such as when you are home or away. Once your schedule is set, advanced features like Smart Setback can help you save without lifting a finger or sacrificing comfort. While those two simple steps will take you a long way, the savings don’t have to stop there. To take your savings to the next level, continue with these simple steps:
  3. Make informed decisions: The Côr Energy Reports within the web portal provide you with personalized savings tips, informative comparisons, and even detail energy usage data to help you make informed decisions about managing your home comfort and energy usage.
  4. Proactively manage your energy use: When you’re not following your typical schedule adjust your temperature accordingly using the Touch•N•Go® feature or by setting a vacation schedule.
  5. Use your mobile app or web portal: The app is your pocket-sized thermostat, making it easy to adjust anytime, anywhere! The Touch•N•Go buttons make it easy to manage your savings while on the go.

What is the Touch•N•Go feature?

The Touch•N•Go feature allows you to quickly change between your standard comfort profiles.

Can I change my temperature temporarily?

You can temporarily override your schedule by using the Touch•N•Go feature or by manually changing set points. The Touch•N•Go feature gives you a simple, quick way to change between your pre-programmed comfort settings ideal for those on-the-go changes. To change the temperature settings manually simply click on the Heat To or Cool To button and then use the up / down arrow to adjust the temperature set point.

By default changes made manually or with the Touch•N•Go feature will be held until your next scheduled activity change. When time arrives for the next scheduled activity the thermostat will return to its normal schedule. You can override this default by clicking the “Hold Until” button below the Touch•N•Go profile or you can change this default Hold Time setting permanently on the thermostat (Main Menu > Settings > Preferences > Default Touch•N•Go hold time) or on the web portal (Settings Tab > Preferences Tile > Hold Action).

What are Comfort Profiles?

Comfort Profiles define key comfort settings like temperature set points and are used in the scheduling process to make managing your comfort easier. The thermostat comes pre-programmed with four default Comfort Profiles – Home, Away, Sleep, and Wake. You can also add up to six custom Comfort Profiles.

How do I set my weekly schedule?

The Carrier Côr thermostat comes pre-programmed with a schedule design to meet a typical 9 to 5 schedule. The easiest way to modify this default schedule is through the guided scheduling feature on either your thermostat or mobile app (Main Menu > Schedules > Guided Schedule) or through the web portal (Schedule Tile > Guided Schedule Button). For more extensive customization the easiest way to modify your schedule is through the web portal’s scheduling tile.

How do I change my temperature settings for the Comfort Profiles?

As with the schedule, the easiest method is to make changes to your Comfort Profile settings through the guided scheduling feature. Alternatively, you can modify comfort profile settings or create custom profiles from the thermostat and mobile app in the profiles menu (Main Menu > Profiles > Temperature Profiles) or from the web portal within the scheduling tile in the “Edit Comfort Settings” section on the right hand side.

Can I have alerts and reminders sent to my email?

Yes. By default alerts and reminders will be displayed on your thermostat and an email will be sent to you. Disabling email notifications can be done on the web portal in the Reminders & Alerts tile (Reminders & Alerts > Preferences > Email alerts).
