Abstract
A secondary controller that controls a secondary device and is used with a primary controller that controls a primary device. The secondary controller detects primary control signals sent to or from the primary controller, and controls the secondary device based on the detection such that the secondary device does not operate when the primary device is operating, or so that the secondary device operates in a relatively lesser capacity when the primary device is operating. Also described is an outdoor air cooling and ventilation apparatus for supplying outdoor air to an indoor space, which may optionally be used with the secondary controller.
