Abstract
A wall mount (for example, a window mount) dual fan includes two independently controlled fans controllable to move air in the same direction or in opposite directions. Each fan includes a temperature sensor to measure temperature of air moving through each fan. The fans are energized periodically for a short time period to make accurate temperature measurements. When the combined temperature measurements indicate an advantage from fan operation, the fans are activated.
