  • Effective attic ventilation requires air to exit at or near the peak of the roof and replacement air to be drawn in under the eaves of the house, via soffit venting. The Home Ventilating Institute (HVI) recommends that powered attic ventilators provide at least 10 air changes per hour to equalize attic temperature.

    Answer: 
    Thank you for your question on the model 345SOWW roof mounted solar powered attic ventilator. The only thermostat available for this unit is the CWT45, a cold weather thermostat that will turn the power off when the attic temperatures go below 50 degrees. The thermostat activates the motor at temperatures above 61 degrees to vent air from dawn through dusk.

    Answer: 
    Thank you for your question on the model 345SOBK roof mounted solar powered attic ventilator. The installation instructions are only a recommendation of how and where the unit should be installed. Installation on the south, southwest or west side of the home normally gives you the best opportunity for the solar cells to receive the brightest and longest amount of sunlight.
