Abstract

A movable barrier operator system wherein one or more of the various components of the system is configured to operate selectively in at least either of two operational modes. Each operating mode is characterized by a corresponding energy usage profile. The operational status of the system is monitored and operating modes are selected that serve both to substantially ensure proper operation given current likely operational expectations and an overall desire to reduce energy consumption.
