Power your fan after dark:
The addition of the Solar Controller with Dual Mode Technology will enable your Solar Powered Attic Fan 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 8 minutes every half-hour in order to power the fan. This will allow your attic temperature to continue to drop after sunset and help remove the hot, stagnant air that can build up on those warm summer evenings.

Real-time status updates:
The remote control readout on the Solar Controller sends a radio signal through your walls and ceiling to give you a real-time status update on fan operation to let you know if your fan is running and if the power source is from the solar panel or the house electricity.

No more questioning if your fan is running! This patent pending, industry-first advancement will give you the peace-of-mind that your fan is functioning and your attic is being ventilated.

An intelligent device:
The Solar Controller monitors both temperature and humidity optimizing your fans operation for maximum performance in all weather conditions.

The Solar Controller intelligently limits the amount of electricity used to power the fan, so it is a perfect alternative to traditional electric powered vents. With the built-in temperature and humidity sensors, the Solar Controller can monitor attic conditions and utilize solar power or house electricity to optimize the run-time of the fan by removing excessive heat and moisture.
