How Do I Set a Schedule on My Honeywell T6 Thermostat?

You can set a schedule on your Honeywell T6 Thermostat by first enabling the schedule option within the main menu. You will then be able to program the various schedule options for the thermostat. You can return to the main screen of the Honeywell T6 Thermostat once you have finished.

A schedule tells the thermostat how to respond based on the time of day. By setting a schedule, a user can have their thermostat activate automatically based on the current time and day of the week. This way, the user won't necessarily have to manually adjust the device every time the temperature should change. But please note that a schedule can be overridden if a hold is applied.

Keep in mind that if you pair the T6 Thermostat with a system that uses an interactive automation platform like Total Connect 2.0 or Alarm.com, then you will no longer be able to set permanent holds locally at the thermostat. Also, if you use the T6 Thermostat with Total Connect 2.0, then you should instead program schedules through that platform so that you can edit them from anywhere. This is preferable to adjusting schedules locally at the thermostat itself, as you will be restricted to making all adjustments at the actual thermostat.

For this FAQ, we will focus on setting up schedules locally at the T6 Thermostat itself. If you want to instead make schedules through Total Connect 2.0 or Alarm.com, as is recommended, then you will need to follow the appropriate steps for that platform. Complete the following steps to set a schedule on your Honeywell T6 Thermostat:

1. Enable the schedule Start from the main screen of the Honeywell T6 Thermostat. Press the Menu button at the bottom. Press the right arrow once to display Schedule. Press Select at the bottom. If the screen displays "Schedule Off", it means that the schedule option is currently disabled. Press the Sched. On/Off option in the lower-right corner. The screen should display "Schedule On" for a few seconds. This indicates that the schedule option is now enabled. The device will then allow you to begin programming the specific schedule options.

2. Program the weekday schedule. The Honeywell T6 schedule is split into weekdays (Monday thru Friday, M-F) and weekends (Saturday thru Sunday, S-S). The schedule works by having a "Wake" time when the thermostat will begin heating or cooling the building to the "Home" temperature. Then the "Sleep" option will adjust the temperature to a specified value when the programmed sleep time occurs.

Keep in mind that "Wake" and "Sleep" don't necessarily have to be the times you wake-up and go to sleep. They could be used for different times, such as when you leave for work and when you return home. You can set these programmed thermostat temperatures and times however you want, and the system will respond accordingly.

With "M---F Wake" displayed, press Select at the bottom. You will then set the time of day when the thermostat will begin adjusting the temperature to the "Home" setting. Press the displayed time on the right side of the screen to begin adjusting the time. Then use the + and - buttons to adjust the wake time. Press the Select key at the bottom to confirm the selected time. The T6 will display "Saved" to confirm that the wake time has been saved. At the saved time, the thermostat will apply the "Home" temperature that has been set in the next menu.

With "M--F Home" displayed, press Select at the bottom. First you will set the "Cool to" temperature. This tells the thermostat to begin cooling if the current temperature is higher than the "Cool to" temperature. Click the displayed temperature to begin adjusting. Then press the Select button to confirm. The screen will display "Saved".

Next you will set the "Heat to" temperature. This tells the thermostat to begin heating if the current temperature is lower than the "Heat to". Again, press the displayed temperature to begin adjusting and the Select button to confirm the selection. After the selection, the screen will display "Saved".

For proper operation, the "Cool to" temperature should be higher than the "Heat to" temperature. If the temperature is in between the "Cool to" and "Heat to" temperatures, then the HVAC unit will remain inactive until the temperature rises or falls outside the programmed threshold. These settings will determine how the T6 responds after the "Wake" time, but before the "Sleep " time. For proper operation, the "Wake" time should be set to an earlier time of day than the "Sleep" time.

The next step is to adjust the "M--F Sleep" schedule. With this option displayed, press the Select key at the bottom to begin adjusting. The sleep time is time of day when the thermostat will shift from the set home temperature to the set sleep temperature. Click on the displayed temperature, and use the + and - buttons to adjust the set time. Press the Select button to confirm the time.

The device will then allow you to adjust the "Cool to" and "Heat to" temperatures for the M-F Sleep time. This is the same principle as the Home setting. Use the + and - keys to adjust the temperatures, and press the Select button to confirm each selection. The screen will display "Saved" when the selections have been confirmed.

3. Program the weekend schedule. The weekend schedule is set in the same manner as the weekday schedule. The only difference is that these settings will be applied for Saturday and Sunday only, as opposed to Monday thru Friday. The menu options are "S--S" instead of "M--F". Apply the same principles outlined in Step 2 for programming the weekday schedule to successfully program the weekend schedule.

4. Save the changes. Option after "S--S Sleep" is "Done". With "Done" displayed, press the Select button at the bottom of the screen. The T6 will take a brief moment to save all the changes. Then press the Back button in the lower-left corner to return to the main screen.
