Unlocking the thermostat:
Touch the “lock” icon.
Enter the pin by touching the +/- icons. Touch SELECT after each digit is entered to advance to the next digit.
After touching SELECT once the last digit is entered, the thermostat will return to the main screen in the Unlocked state.
Locating my pin:
The screen lock pin is not adjustable on any Honeywell thermostat. To obtain the pin, remove the thermostat faceplate by pulling it gently away from the wall plate. On the label on the back of the thermostat face-plate, locate the DATE CODE. (4-digit number located on the right side of the label)
The pin is calculated by adding 1234 to the date code. (For example: A date code of 1644 would have a pin of 2878)
