Before installing, I tested them in my freezer. They are supposed to be fully closed at 35 degrees, so a freezer at zero degrees will more than do the job. You must stand them perfectly upright in the freezer - the same orientation as when they're installed, otherwise even a good one won't work properly. Apparently, the louvers are somewhat gravity assisted. After 30 minutes in the freezer, one of the three was still wide open. I exercised the louvers and found that the mechanism was sticking (hence, 4 stars). After working on it a bit, I found a rough spot on the bimetallic spring and fixed it. Then I took all three out of the freezer and sat them upright in front of a floor fan - the temperature was roughly 80-85 degrees (they are supposed to be fully open at 75). All three opened okay.Installation orientation is critical. Look for the word "TOP" molded into the plastic. The four screws are 3/16" hex-head capscrews. Tightening them with an L-shaped hex wrench is a lengthy process. Fortunately I had a 3/16" hex to 1/4" socket drive adapter and a 1/4" drive universal joint, so I tightened them with my cordless drill, which took less than 1 minute for each vent.Note that the temperature trip-point is adjustable, although I didn't need to do so. There is a nylon screw on the end of the vent which twists the bimetallic spring mount, the same way as old spring-type thermostats worked. ### ⭐⭐⭐⭐⭐ I like the automatic feature *by D***A on August 28, 2021* Installed 12 of these on a home with a ground water problem under the joist floor with the addition of fans directly behind four of these. I tested one before installation by placing in my freezer and it did indeed close!I was concerned the fans would cause chatter on the louvers but the did not make any additional noise. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/5741749-witten-automatic-vent-b-eblack-mb-energy-saver-foundation-auto](https://www.desertcart.tw/products/5741749-witten-automatic-vent-b-eblack-mb-energy-saver-foundation-auto) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-04-22*
