The WaterWizardâ„¢ evaporative cooling optimizer is designed to provide evaporative cooling control while reducing water waste. It measures the outside temperature and humidity then adjusts the water supply to provide only the water needed for maximum evaporative cooling, the company says. On cool or humid days, the device senses when the evaporative cooling potential is low and reduces the water supply to operate more cost efficiently, states the company. On hot or dry days, it increases the water supply to meet the increased maximum cooling potential, says the manufacturer.
