Full Instructions to Set a Pin and Lock:

Start by unlocking the Terra thermostat, if it’s currently locked. You can do this by pressing the check mark icon.

On the home screen, locate and select the settings icon. It is represented by a gear symbol. Once in the settings menu, scroll through the options until you find the display lock icon. It is represented by a padlock symbol.

Select the display lock icon to activate it. You will notice the icon turning blue. Next, use the arrow buttons on the thermostat to navigate to the option to switch the lock to the “locked” position.

Once you’ve reached the “locked” position, select the check mark icon to confirm your selection.

Now it’s time to set a 4-digit PIN code. Use the arrow buttons again to input your desired code. For example, if you want to set your PIN as 1234, press the arrow buttons to enter each digit in the correct order.

After entering each digit, select the accept button to confirm it individually. Repeat this process for all four digits of your PIN.

Once you have finished entering and confirming your PIN, press the “X” button repeatedly to return to the home screen.
