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. Press and hold the mode button for about three
seconds. The display will show U1 and the letter F in
the center.
2. Press the mode button until the display shows U3 and
Of.
3. Press the up or down button on the right to change it
from Of to On. You will also see a padlock, which indic-
ates the keypad is locked.
4. Press the fan button on the left to exit this screen.
