The Tamarack Technologies, Inc, HV1000 R50 Wi-Fi Whole House Fan easily mounts in the attic on 16 or 24 inch on center joists. The fan can be mounted horizontally or vertically. The HV1000 R50 Wi-Fi capability is built into the unit and and can be controlled by using an app on your smart phone or tablet. The unit is also compatible with both Amazon Alexa and Google Home.  This 1000 CFM* fan quickly circulates air and cools your home whenever the outdoor air is cooler than the indoor air. The HV1000 R50 Wi-Fi  operates at two speeds  to exhaust hot air, indoor air pollutants, allergens, moisture, and odors out through the attic vents or gables while pulling cool, fresh air into the home through the open windows. The air exchange naturally cools your home and can improve the indoor air quality.

Like all Tamarack Technologies HV Series Whole House Fans, the HV1000 R50 Wi-Fi features a unique self sealing door design. The unit includes R50 insulated  doors that open automatically when the  fan is operating and seal shut automatically when the fan is off. The insulated door design prevents the cool air from your living space from escaping to the attic. The insulated doors also prevent heat loss through the attic during cooler months.

Installing an HV1000 R50 Wi-Fi Whole House Fan reduces energy consumption and saves money. Whole House Fans use 10% of the energy that a central air conditioning system uses.  Because the HV1000 cools your home, it reduces the amount of energy needed to run your air conditioning  which reduces your energy bill.
