Continuing the discussion from Smart air vents : [image] Smart air vents If you’re a bit of a hacker this is the “better” solution http://www.smarthome.com/6-inch-diameter-normally-open-electronic-hvac-air-duct-damper.html Pair that with a relay switch and your system will be way more efficient…

If placing one in ALL of your ducts I’d really be concerned with a system failure causing far too much back pressure and killing your HVAC system, with the Keen/EcoVent at least they have some additional failsafes. Just something to keep in mind.

Ya, I appreciate that and agree with your point. It has been brought up for discussion elsewhere, and after careful consideration, I have come to the conclusion that it’s not a real problem (as long as the house is never in a situation in which power goes out only for the ‘smart system’, but not fo…

Sweet! If you don't mind sharing.... What specific physical devices did you use? [image] Suncourt 6-Inch Normally Closed Electric HVAC Duct Damper & Power Supply Heat or cool only occupied rooms in your home to Conserve Energy and reduce energy costs with this electronically controlled …

Awesome! Thanks a lot for all of the details. This goes a long way toward figuring things out. I mean, even if I don’t end up getting exactly the same pieces of equipment, it’s always good to see what others have already done. Since you’ve had it going for so long now, I assume it’s a proven concep…

[image] Benji: …a system failure… I just reread this, and may understand it differently now…or just didn’t get your full point originally… So, do you mean if the SmartThings system fails? i.e. if it somehow fails to open them back up and it’s going along with a bunch of them closed because i…

Wow…even more money lol I guess this is why people get a truely zoned system from the get-go. Trust me though, if I had been offered that choice over a decade ago when we bought the place, I would have. Unfortunately, it was already done by the time we came along. So, are we talking either/or, or…

Thanks. I will check out the URL as well. So, with the bypass damper, I was thinking that each line of ducting that I have a motorized damper in would need this (i.e. use the bypass damper instead of a normal one), but are you saying that there would only need to be one for the entire system (takin…

Hmmmm(crunch, crunch, crunch…)…So, do you mean that you will have the bypass damper set to normally closed, and then it will open if it senses x-pressure build up, or something like that?

Bypass adjustment is based on the pressure in your system. The gravity controls its damper. Been following your posts, and I really think you should go with a Honeywell zoning panel. And installed by its manuals. You are risking a lot of money if you burn your heat pump. I have had one professionall…

Thank you for your input. Along with making sure to build something that’s safe (for me and the HVAC system itself), I am also trying to come up with something that could be implemented for relatively low cost. I totally understand that, in some cases, since it can’t be done safely, it shouldn’t b…
