LOCKOUT ENABLE—Enable or disable adjustments to prevent unauthorized changes from 
the touchscreen interface. When LOCKOUT is changed from NO to YES, the user must 
enter a 3-digit PIN. After setting the LOCKOUT to YES and entering a PIN, the thermostat 
locks when the user returns to the home or the dormant screen. 
When LOCKOUT is enabled: 
•  The user must enter the 3-digit PIN after pressing any button on the home screen.   
•  If the PIN is entered successfully, the thermostat is unlocked until the dormant 
screen displays.   
•  After 5 failed attempts to unlock the thermostat, a notification (fault) is sent through 
the Wi-Fi to the registered owner of the thermostat. Additional unlock attempts are 
not allowed for 15 minutes. 
NOTE If the user enables LOCKOUT but does not save a PIN, LOCKOUT automatically 
disables (sets back to NO). 
SET LOCK PIN—The end user can choose or modify their own 3-digit lock PIN for the 
thermostat.   
One digit of the 3-digit PIN flashes to indicate which digit is changeable using the up and 
down arrows. To change which digit is adjustable, touch the digit on the display.  
NOTE If LOCKOUT ENABLE is set to NO, the SET LOCK PIN screen does not appear.

cloth. During this time, a 10-second countdown value shows and then normal touchscreen function resumes.
