About $20, and adjustable from 0.1" to 10" H2O. Just put a small hose to the outside, and when the DP gets above your set point it signals you controller to shut off the fan.<br /><br />Hope this helps<br /><br />Mike Swift aka tomswift tomswift@cruzio.comMike Swifthttps://www.blogger.com/profile/06903727458862323673noreply@blogger.comtag:blogger.com,1999:blog-1280642420599607924.post-25150981542744965942012-07-19T19:08:09.467-06:002012-07-19T19:08:09.467-06:00"Prevent" is a strong word. Let's s..."Prevent" is a strong word. Let's say that I tried not to make it any worse than a simple mechanical control. The software in my controller won't switch the fan from off to on except in response to a screen touch (although it may switch speeds). In the event of a power failure, the controller always comes up in a state with the fan off. Individual screens presented by the controller all have some way to immediately turn the fan off.<br /><br />If I were building a complete system from scratch, I can think of several things I would at least look at that might determine whether sufficient windows are open. Measuring the AC voltage, the motor's current draw, the fan's RPM, and overall air flow are all feasible in one fashion or another. Various combinations of those values would indicate insufficient flow and the controller could shut the fan off (along with displaying a message about what it had done).Michael Cainhttps://www.blogger.com/profile/01472223216496790376noreply@blogger.comtag:blogger.com,1999:blog-1280642420599607924.post-66238702635644507842012-07-19T14:39:46.497-06:002012-07-19T14:39:46.497-06:00So, how do you prevent the closed window/ fan runn...So, how do you prevent the closed window/ fan running problem ?Unknownhttps://www.blogger.com/profile/07816549335803914247noreply@blogger.comtag:blogger.com,1999:blog-1280642420599607924.post-68392053970628689832012-07-19T11:19:57.978-06:002012-07-19T11:19:57.978-06:00When I was thinking about what I wanted to build, ...When I was thinking about what I wanted to build, I did think about a web-enabled (or at least LAN-enabled) system. I knew I would need a relatively sophisticated UI to meet my wife's requirements, and that would be easier to build to run in a browser on a PC or smart phone where someone else had dealt with the graphics display and touch issues. In the end, I decided against it for two reasons: (1) it increased the level of other in-home tech necessary for the system to work and (2) it seemed to me that it would increase the odds that the fan would get turned on with no windows open, and no one around to open the windows. The contractor who installed our fan had several horror stories about fans running with no windows open.<br /><br />That's not to say a web-enabled fan is a bad idea; I just didn't think it met the primary goals I was trying to accomplish.Michael Cainhttps://www.blogger.com/profile/01472223216496790376noreply@blogger.comtag:blogger.com,1999:blog-1280642420599607924.post-86502829174363838972012-07-18T16:18:46.773-06:002012-07-18T16:18:46.773-06:00Michael,
