ADVANCED PROGRAMMING OPTIONS
Keypad lockout
The keypad lockout feature lets you "lock" the thermostat so nobody can change
the temperature – or make any other changes – by pressing buttons. Keypad
lockout is not activated when the thermostat is installed. Here's how to activate it.
1. Open the door.
2. Press and hold the home and sleep buttons under the
display simultaneously for about three seconds.
3. Press the up button at the top right of the display. You will
see U3. (If you don't, continue to press the mode button,
cycling through the options until you get to U3.)
4. Press the mode button on the left. You will see U3 and
On beneath a padlock icon. This indicates that the keypad
is now locked.
5. Press the done button on the right.
6. Close the door.
