How does a Greenhouse Autovent work?
A strong metal tube contains a mineral wax that expands with heat. This pushes a piston which opens the auto vent via a balanced linkage. As the temperature drops, the wax shrinks and a strong spring closes the vent and resets the piston.
Your opener can be mounted all year round, however, your cylinder must be unscrewed by
1) Use of a heat source in your greenhouse
2) Winter storm, winter must be secured with the safety belt
