5 Go to customer.honewell.com and download the Installer and System Test Pocket Guide. It shows how to access function 670 to turn off the screen lock.

5 Instead of going to mail menu by hitting the center button hold down the button to the left and right of center to get the FULL menu options. The link below is a different manuel that explains the process. http://www.aercoindustries.com/sites/aerco/files/TB8220U.pdf
