Operation Using the Door Control SMART CONTROL PANEL Navigation Buttons Push Bar Screen Light Button PUSH BAR Press the push bar to open and close the door. 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 using the door control, see page 6. NAVIGATION BUTTONS Use the navigation buttons to make selections and program features. 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. The following features are accessible through the screen using the navigation buttons. LEARN A DEVICE Any compatible remote controls, wireless keyless entry, or MyQ™ accessories can be programmed to the garage door opener by accessing the menu and using the navigation buttons on the Smart Control Panel. 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. Factory default is set to off. The garage door opener will Beep and the lights will Flash before closing the door. If the door encounters an obstruction while closing, the garage door opener will make a second attempt to close the door. If the obstruction has not been cleared after the second attempt, the garage door opener will reverse open, stop and WILL NOT close until the obstruction has been cleared. 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. AUTOMATIC LIGHT Motion Sensor Factory default is set to on. This feature automatically turns on the garage door opener lights when motion is sensed. The lights will come on for the set period of time, then shut off. If using the garage door opener light as a work light disable the motion sensor, otherwise the light will turn off automatically if you are beyond the range of the sensor. Light Feature The lights will turn on when someone enters through the open garage door and the safety reversing sensor infrared beam is broken. MAINTENANCE ALERT (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 factory setting for the MAS feature is off and can be activated at time of installation. Contact your installing dealer for service. 5
