change, and a convenient space to keep track of your settings. For more details on each homeowner programming

2. Press the MENU soft key. The display will show the first level of the Homeowner Programming Menu.

• The
(Action) button selects the highlighted menu item
• The soft key labeled HOME exits the Homeowner Programming Menu back to the home screen
(NOTE: when the HOME soft key is pressed, any changes made on the current menu item are not saved)
• When changes are made to a menu item, pressing DONE will save the changes and go back one menu level
• If a mistake is made during programming, press HOME once, then return to the programming option and
re-enter the information (press DONE to save changes, press HOME to exit)
4. To exit the menu and return to the program operation, press HOME (when available).
If no keys are pressed within two minutes, the thermostat will revert to normal operation. Any changes made but not
