A method and control system for setting travel limit positions of a movable closure, such as a roller or sectional-panel door. The closure is movable between open and closed positions by a drive unit and associated electronic controller in response to command signals received from a remote transmitter. During an installation phase, the closure is moved in a first travel direction towards a desired first limit position in response to a user pressing and holding a command push button on the remote transmitter. The closure is then stopped when the user releases the command push button. If no command push button is pressed for a predetermined time period (e.g. 5 seconds), data representative of the closure's stopped position is stored in a memory. This data thereby defines the first travel limit position. A similar procedure may be used to store data representative of a second limit position.
