Determining your programming schedule
Your Côr 5 or Côr 5C give you the option of programming every day of the week differently. It is pre–programmed at the factory with the same settings for all seven days as shown here

Monday Through Sunday	Time	Heat	Cool	Fan *(On/ Auto)**
Wake	6 AM	68	78	Auto
Away	8 AM	60	85	Auto
Home	5 PM	68	78	Auto
Sleep	10 PM	60	82	Auto

Fan On = Fan runs continuously even if there is not a call for heating or cooling
Fan Auto = Fan only runs only during active heating or cooling times.

You can change those settings easily. By default each day in your schedule has four time periods. The thermostat thinks of these time blocks in terms of when people wake up, when they leave for the day, when they return home, and when they go to sleep. You can change your period to two per day if you have someone home most of the day and don’t want an away period. See Changing Number of Periods section below. Use this blank grid to make scheduling quicker by determining those time periods based on your own schedule along with how warm or cool you want your home to be at those times. Change the days of the week if you have several that are the same such as Monday – Friday.

OPERATING THE THERMOSTAT

Using the thermostat to turn the heating and cooling system off
Here’s how to use the thermostat to turn the heating and cooling system off or switch between the system modes.
Touch the HEAT/COOL button repeatability until the desired option has the applicable icon over the text at the top of the screen. (Aux
Heat, Heat, Cool, Auto or Off). Not all names may be available based on the heating and cooling equipment installed.
After 10 seconds of inactivity the screen will return to the Home Screen accepting the mode selected, or press DONE to exit to Home Screen.
See instruction for air circulation fan feature under Advanced Programming.

Using the fan button on the Home Screen
The fan distributes the heated or cooled air throughout your home for a more even temperature in all spaces. You can set the thermostat so that the fan runs only during your heating and cooling cycles (auto mode), or run continuously (On).

Touch FAN. The current fan mode will be displayed. If you wish to toggle between ON or AUTO use the Up/Dn arrows.
After 10 seconds of inactivity the screen will return to the Home Screen accepting the Fan mode selected, or press DONE to exit to

Home Screen.
See instruction for air circulation fan feature under Advanced Programming.

Using Auxiliary Heat (heat pump systems only)
Auxiliary Heat is useful when the heat pump system can’t keep up with demand. Systems with heat pumps automatically use auxiliary heat when it’s too cold outside to heat the house without additional help. The display indicator for this is at the top of the screen with the text “aux heat” and a flame above the words when actively heating. You can manually turn on the aux heat but you will want to avoid using Auxiliary Heat exclusively, because electric resistance heat is the most expensive option. If you have a Hybrid heat system and the auxiliary heat is a gas furnace then it will be desirable to run auxiliary heat below a specific outdoor temperature due to energy cost preferences. Your dealer will have setup your system for Hybrid Heat with the best auxiliary heat settings. And of course, if you suspect a problem with your heat pump, call your heating and cooling dealer immediately.

Setting your thermostat to Auxiliary Heat

Touch HEAT/COOL button until there is a flame over “aux heat” at the top of the screen.
After 10 seconds of inactivity the screen will return to the Home Screen accepting the Aux Heat Mode, or press DONE to exit to Home Screen.

SPECIAL FEATURES

Hybrid Heat (heat pump with a furnace system only)
This thermostat works with the Carrier or Bryant Hybrid Heat systems offering maximum comfort and economy by automatically controlling whether your system delivers heating with the heat pump, with the furnace, or with both options working together.

Outdoor temperature display
The thermostat displays the outdoor temperature when the thermostat is connected to Wi–Fi and the postal code is entered or when there is an outdoor air temperature sensor installed by your dealer.

To set the postal code for weather and outdoor temperature:

Touch MENU. Touch NEXT until Wi–Fi is blinking. Touch NEXT.
Use the Up/Dn arrows until POSTAL CODE is blinking. Touch NEXT.
Use the Up/Dn arrows to set the number touching NEXT after entering each number.
Touch DONE to return to Home Screen.

Auto changeover
The thermostat displays one of five modes (based on equipment installed): heat, cool, Aux heat (heat pump version only), heat cool (auto mode) and off. When the mode selection is for both heating and cooling – auto mode – the thermostat is in auto changeover mode. This allows the system to switch from heating to cooling – or from cooling to heating–to maintain the temperatures you’ve programmed. It does this automatically. The temperature between heating and cooling set points is called the ”Deadband” which is 2F from the factory. Your dealer can adjust the Deadband from 1F to 6F. On Wi–Fi models you can change this from the mobile app under the menu, System Configuration.

Smart Recovery
The Smart Recovery feature transitions your home from one temperature period (wake, day, evening, sleep) to the next so that the your home’s temperature matches the temperature setting at the start of each time period. This means, for example, that if your sleep period temperature setting is lower than the period that precedes it, the thermostat will start cooling down the home before the beginning of the scheduled sleep period. It does this at an energy–efficient rate. This not only helps make your home as comfortable as possible, it also makes your thermostat more cost effective. Call your dealer to adjust Smart Recovery settings.

Troubleshooting

Auxiliary Heat is displayed (heat pump and Hybrid Heat systems only)
Auxiliary heat on applies only to the heat pump version. If it is on, you will see auxiliary heat icon at the top and a flame icon above it when it is heating. When it is displayed, it means the system has determined that it’s too cold outside for your heat pump to heat the house without help, so it’s getting help from the electric heaters. This happens automatically. You can also put the system into Aux Heat manually by touching the HEAT/COOL button on the top right of the thermostat.
