The valve itself is opened and closed by the control cable. Adjust so the valve is shut when it should be. The screw adjuster just tunes the +/- small changes that are read by the ether filled copper coil. This is in the air flow so that if it gets a blast of hot or cold ambient air it will open or close the valve to compensate. That's the theory anyway but it's quite crude and you'll mostly not notice any changes. The screw is set by the maker after testing and should have a blob of paint on it to show it's original and not tampered with.
