How to Adjust the Time & Date on a Honeywell Thermostat

Press the "Set" button on your thermostat to bring up the time adjustment screen. Using the up and down arrows on the keypad, scroll through the numbers until you've reached the present time.

Press "Set" on your keypad once more to move into the date adjustment screen. Use the up and down arrows to scroll through the days of the week until you find your current date.

Press the "Run" button on your keypad. This will save the information you have imputed and exit the program, bringing you back to the main screen.
