The stainless steel cylinder contains a temperature sensitive mineral wax that expands as the temperature rises. This increases the pressure inside and pushes out a steel pin that is connected to arm of the opener.This arm then opens the roof vent. As the temperature drops, the wax contracts and allows the vent to close.
