My old electric fan had a thermostat. Does the SunRise?
Yes, there is a thermostat available. Unlike an electric fan, which depends on the thermostat to tell it when to come on, the SunRise uses the thermostat to tell it not to come on when the attic is already cool. It is pre-set to allow the fan to come on at 80 degrees and to go off at 65 degrees, which is particularly desirable in cool, dry climates.
