Automatic vent operators on the roof and base vents require no electricity or batteries. The vent operator contains a paraffin (wax) that expands when the temperature reaches about 65°F, pushing the vent open to its fully opened position at about 85°F. As it cools and the paraffin contracts, the operator's springs draw each vent closed. It is adjustable within approximately 5°F and easily detachable for manual operation.

The vent opener cylinders can be replaced when they stop working.
