The Timer-to-Close feature is not available on all door controls.Below is a listof door controls with the
Timer-to-Close feature:

The Timer-to-Close feature automatically closesthe garage door after a specified time period. DO NOT
enable TTC if operating a one-piece door. TTC is to be used ONLY with sectional doors. Factory
default is setto off. The garage door opener will beep and the lightswill flash before closing the door.
The TTC feature will deactivate if the garage door encounters an obstruction twice; or the safety
reversing sensors are incorrectly installed. The garage door will reverse open and WILL NOT close
until the obstructions are clear or the safetyreversing sensors are correctly installed. When the
obstruction has been cleared or the safetyreversing sensors have been aligned, the door will close
when the garage door opener is activated. TTC WILL NOT work if the garage door opener is operating
