Thermal vent control

The thermal vent control has been installed for a few days and it works really well. It only cost nineteen dollars to purchase, and it clamps on, which makes removal real easy. I would not want to leave in on during the winter, and I am glad I did not have to drill any holes in the frame for the installation.
It begins to open at sixty degrees, and as the greenhouse warms it eventually opens the vent completely. I have been checking it frequently since it has been installed, and I can see that it is adjusting the opening as the greenhouse heats and cools. After sunset and the temperature drops below fifty nine the vent is closed.
The weather is so variable in upstate New York that this addition is going to come in real handy.
