This model is activated when the three speed switch is turned to any of the three speed selections. The dome cover is opened when the dome up switch is activated and closed when the down feature is selected. To activate the fan blade the built-in thermostat must be turned to a lower temperature than the current interior temperature. The fan will shut off when pre-selected temperature is reached but dome stays open for ventilation until the down feature is selected or the built-in rain sensor automatically closes the dome. A built-in manual knob can be used to close the dome in an emergency or to adjust the dome to a desired partially open height or to override the rain sensor. For storage the dome switch must be in the down position and the three speed switch to the off 0 position. The vent has a reverse switch for either intake or exhaust. The fan draws only 3 amps. max. and has a built in 6 amp fuse which is easily accessible on the face.
