The options you'll find in the App's Open Settings are almost the same as the options you'll find in the Door Opener's Open Settings, but there is also an extra feature which is not available on the Door Opener itself: Computed Sunrise.
Manual
The "Manual" option disables the automatic door opening.
To open the door, you will need to press the UP button on the Door Opener itself, or the UP arrow in the app's Home Page.
Sensor
The "Sensor" option uses the light sensor to open the door after the sun rises at dawn.
(The light level the Door Opener regards as dawn can be altered inside the "LUX Settings".)
Timer
The "Timer" options allows you to set the time you would like the door to open.
When the screen reads "Timer", tap the MENU button to enter the setting.
Use the UP and DOWN arrows to set the hour value. Then tap the MENU button.
Use the UP and DOWN arrows to set the minute value. Then tap the MENU button to save the Timer.
Computed Sunrise
The "Computed Sunrise" option uses your location to calculate the time that the sun will rise in your area - this is updated daily to keep up with the changing seasons.
When the screen reads "Computed Sunrise", tap the MENU button to enter the setting.
Use the UP or DOWN arrow to increase or decrease the Offset if you would like. The "Offset" refers to a period of time before or after sunrise that the Door Opener will open the door.
You can increase or decrease the Offset by increments of 5, up to 90 minutes.
EXIT
"EXIT" is the last option inside any area of the Settings Menu. Tapping the MENU button when "EXIT" is on the screen will close the Settings Menu and take you back to the Home Page.
