Feature Overview
SCREEN
The screen will display the time and temperature until the menu button is pressed, and then it will
display the menu options. If there is a problem with the garage door opener the screen will display the
Diagnostic Code.
LIGHT BUTTON
Press the LIGHT button to turn the garage door opener lights on or off. When the lights are turned on
they will stay on until the LIGHT button is pressed again, or until the garage door opener is activated.
Once the garage door opener is activated the lights will turn off after the specified period of time (the
factory setting is 4-1/2 minutes). The LIGHT button will not control the lights when the door is in
motion. The duration of the light timing can be adjusted by accessing the menu using the navigation
buttons.
MOTION SENSOR
The motion sensor will automatically turn on the garage door opener lights when motion is detected.
The lights will come on for the set period of time, then shut off. The factory setting is on and set at
4-1/2 minutes.
LOCK
The LOCK feature is designed to prevent activation of the garage door opener from remote controls
while still allowing activation from the door control and keyless entry. This feature is useful for added
peace of mind when the home is empty (i.e. vacation).
TIMER-TO-CLOSE (TTC)
DO NOT enable TTC if operating a one-piece door. TTC is to be used ONLY with sectional doors.
Factory default is set to off. TTC can be set to automatically close your garage door from the fully
open position after a specified period of time (1, 5, 10 minute intervals or a custom setting up to 99
minutes). The garage door opener will beep and the lights will flash before closing the door. The
screen on the door control can display the status of the TTC. TTC WILL NOT work if the garage door
opener is operating by battery power or if the safety reversing sensors are misaligned. This feature is
NOT intended to be the primary method of closing the door. A keyless entry should be installed in
the event of an accidental lock out when using this feature.
MAINTENANCE ALERT SYSTEM (MAS)
This feature assists the homeowner in ensuring the garage door opener system stays in good working
condition. A maintenance alert message will display on the screen indicating the garage door opener
may be in need of maintenance.
The MAS feature MUST be activated at time of installation. The factory setting is off.
