Q: It would be neat to have an option to turn off the backlight when you are away or sleeping instead of keeping the backlight on when there is no one around to see it.
A: Our thermostat will allow you to do this as you described. From the home screen select More > Settings > Preferences > Brightness, select Active/Standby setting. You have a choice from no standby to 90secs in 10sec increments. Hit Done to return to the home screen.
