In a control system (10) having a learning mode (20) such that performance limits can be automatically determined for subsequent use during normal operating modes (40), one or more user manipulable controls (18) are provided to allow a user to selectively adjust the previously automatically determined performance limits. In one embodiment the range of adjustment can be limited. The user control (18) can be located in various positions with respect to the control unit (15). In an exemplary embodiment, the control system (10) comprises a movable barrier operating system such as a garage door opener.
