I tried to integrate a regular transformer to provide separate power for the nest and no go. Likewise the Nest just does not recognize the neutral C output from my system...so ends up with just 40 ma instead of the minimum 200. Some sort of grounding issue I presume. The reason I discovered for the initial issue I had with this adapter is that the specific zone I was using for whatever reason was wired with the power going to the w1 terminal and the neutral to the RH...still works for the system, but Nest saw it as odd and reported as such. Still works though.Works with nest...apparently just. Like many I am the victim of two wire. Well actually I have three and even though I hooked the third up to the common wire terminal on my transformer in the basement, the nest thermostat said there was no power to the RH terminal and yeah...there isn't...by design. I have a boiler/baseboard heating setup that includes taco 571-2 thermostats and I am being specific because there is little info about this setup on the web. The RH wire only gets juice once thermostat calls for heat...so I needed this transformer. Have a wall switch near the stat, so I just installed an outlet at proper floor height and plugged the lockstate into that and ran the cord inside the wall...nice and clean. The funny thing is the nest gave me an error code...n72 I think and tells me there is power to the RH terminal and I am thinking well yeah because I have the transformer connected to the RC and Common and the Nest internally jumps the RH and RC. And of course I am confused when the nest thinks this is a problem. So when I say that checking the wires does not fix the problem the nest site says to just ignore the error code because the nest should work fine, I just have a odd setup. I have to believe there are thousands of 'odd' setups in the Northeast. But it does work fine. the 'just' qualifier is because the VOC sine wave info on the nest reads 30.61 which translates to 21.67 volts after dividing by 1.412. Nests requirement is 20-30 volts...so this thing is in the lower range...but kind of understandable because it is smallish. Still, I like the fact that it is and you can't have it both ways so I just changed my initial 4 star to 5 to be fair. ### ⭐⭐⭐⭐⭐ Perfect - but see installation note! For Emerson Sensi smart thermostat. *by C***L on Reviewed in the United States on March 13, 2017* I did a test install of this on my thermostat and everything worked great! Then I installed it for real (with the backplate, routing the cable, etc) and it didn’t! The thermostat itself seemed to function flawlessly, even without batteries, so I knew it was getting the power. However, the air conditioning wouldn’t turn on. The fan would run, but the compressor wouldn’t turn on, so it was just blowing the air around. (If you are experiencing something like this I have more notes at the end.)This was frustrating since it had just been working, what could have changed! Well, it turns out I flipped the wires. There is a 50/50 chance you get it right, I had gotten it right the first time but not the second.If you look closely one of the wires will have a grey dotted stripe down it’s length. That should be attached to the RC/RH terminal (mine are jumpered). Then attached the plain white side into the C terminal.I paid $28 for this, I see it is now $25. There are significantly cheaper options ($9 Linear TF524) that might work, but I decided to pay extra for this one for 3 reasons: The higher capacity of 300mA was more likely to work (50mA is probably too few), the 20’ cord (rather than 3’), and the fact that my walls a white (the black cord would stand out).I also took the advice of another reviewer and filed a little notch in the backplate to allow the wire to come out without damaging it. I have a picture of this attached.I should also note that I still have a bit of a mystery around this. The Sensi should actually work WITHOUT a C wire, it is one of their big selling points. Mine worked great, except the compressor wouldn’t turn on, meaning that when it was “cooling” the fan would just blow hot air around. I called Emerson and they did troubleshooting with me for about an hour, then sent me a new unit. That unit behaved identically. I ordered this product on a whim thinking it might help (super glad I did).When I installed the C wires backwards the unit would turn on, but the compressor still wouldn’t turn on. When I flipped the wires the heat works, the air conditioning works, everything works perfectly. The Emerson tech I spoke with was great, and quite knowledgeable, but couldn’t imagine why this would be the case. I’m fairly handy, and I have no explanation either. But it all works now, so I’m an ignorant happy camper! ### ⭐⭐⭐⭐ Learned From My Mistakes *by K***B on Reviewed in the United States on November 20, 2017* I have a more modern two wire furnace. They thermostate ran fine but I could hear a relay clicking once the blower kicked on. . Didn't want anything to get messed up in my furnace and this seemed like the easiest solution. The first oneil I received ended up being a dud. I could have saved a lot of time and effort by pulling out the multimeter and testing it before I went to install it. Basically it played out like this... First attempt to install it I plugged wires into the rc and c. Got a no power alert from the nest and only some wires registered. Switched wires around. Same result. Researched. Nest says to only use solid copper wire. Splice in solid copper wire. Same resluts. Pull out multimeter. No voltage. Contact Amazon, new one shipped same day. Received it and tested it with multimeter, 24.3 volts. Splice the wires with newly purchased (15$ for 100 ft, smallest amount I could buy) of two wire solid copper thermostate wire. Success. So far so good. Easy install once researched the necessary steps I had to take to make proper connections and just makinf sure the dam thing worked before running wires. I ended up with the wires from this in the RC and C terminals. I give it 4 stars because I should have done more research about the solid copper wire and I should have tested it before wasting hours of my time. Can't blame them fully for that since they were more then happy to replace it. Lemons happen... But I do feel it should come with compatable wires. It would be work a few bucks more for those not comfortable working with electricity. --- ## 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.id/products/2336392-lockstate-connect-ls-24vac-24-vac-adaptor-for-ls-90i](https://www.desertcart.id/products/2336392-lockstate-connect-ls-24vac-24-vac-adaptor-for-ls-90i) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-13*
