    It'll probably never shut off when it starts to get hot out. I would say 100-110.

    90 to 95 degrees is in most of the manufacturer's guidelines and instructions.

    Not that they do any good anyway...........the attic is still hot as hell.

    I wish there was a cheap way to get the temp of an attic where it is bearable to work in one.

    Studies have shown those fans are a waste of electricity.

    I installed a humidity 1-wire network sensor and temp sensor in the attic and installed the same outside.

    I have the attic fans on computer control.

    First I watched the attic temp rise as the temp outside got hotter. then i turnd on the fan and saw a drop in the attic temp.

    So I created a short program that monitors the sensors

    if the attic temp is 10dF higher then the outsid temp and the temp is higher than 80dF turn on the fans.

    Monitor the humidity in the attic and outside if the attic humidity is higher than outside humidity and ithe attic humidity rises turn off the fans.

    if the temp in the attic rises above 195dF than there may be a fire so turn off the fans.

    Now I think this may be a better way to do the Attic Fans but I do agree ridge vents would be better but the design of my house does not allow for this.
