** Save $20 ** Solar Controller for Solar Attic Fans
Run your U.S. Sunlight Solar Fan into the evening, monitor temperature and humidity, and monitor fan operating status with the award winning Solar Controller®.
Addition of the Solar Controller with Dual Mode Technology will enable your U.S. Sunlight Solar Powered Attic Fan or All Purpose Ventilator to run after sunset, or when there is no light available from the sun. When there is no sunlight available to power the fan, and the Solar Controller has the optional house power connection enabled, the Solar Controller will cycle house electricity for 15 minutes every half-hour in order to power the fan, for up to 10 hours or until solar power becomes available again. This will allow your attic temperature to continue to drop after sunset and help remove the hot, stagnant air that can buildup on those warm summer evenings.
New for 2013 – Improved house power cycling for better ventilation in the evening hours, Quick Connectors for simplified installation, and upgraded technology, including built-in self-restart for improved accommodation of power surges. Solar Controller is designed to work only with U.S. Sunlight Corporation ventilation products. Benefits
