Abstract

A universal electrical control selectively drives either plural motorized window operators for opening or closing one or more windows, or a motorized window operator and plural motorized locks for opening, closing and locking a window. The electrical control comprises an interface circuit for connection to plural output devices comprising either motorized window operators or motorized window locks. An input switch commands window movement to an open or close position. A control circuit is connected to the interface circuit and the input switch and includes an initialization mode for determining if each output device is a motorized window operator or a motorized lock, and output drive mode operable in response to a command from the input switch for driving the output devices through the interface circuit in a lock sequence or a window sequence dependent upon the initialization mode respectively determining if a motorized window lock is connected or is not connected to the interface circuit. The lock sequence comprises opening any lock prior to opening the window and closing the window prior to closing the lock. The window sequence comprises driving the plural motorized window operators in a select desired sequence.
