ABSTRACT:
A self-contained electronic air register controller can easily be mounted directly onto the outside of an air register. When so mounted, the controller engages the register's actuating lever and permits automatic opening and closing of the air register by way of simple programming instructions and/or by way of a temperature sensor. The controller comprises a small battery, a miniature electric motor with a gear/linkage mechanism operable to engage with and to move the register's actuating lever between its OPEN and SHUT positions, and a quartz-clock-based programming means.
