  • Worked for what I needed New thermostat needed a extra power source this was a simple fix
Worked for what I needed New thermostat needed a extra power source this was a simple install and fix

  • Works to power a Nest Gen 4, if you know what you are doing....
First, this did NOT successfully power the new Gen 4 Nest thermostat, the device continued to say low power. I swapped in the Google nest power adapter which supplies 33.57v of power into a 24v system, which is what the Gen 4 device needed, not the fault of this transformer however. Now on to the review...most HVAC techs are going to tell customers to not use Nest/Ecobee style thermostats because they generate too many sales calls to come back and fix the homeowner's handywork. You need to understand the basics of how the 24v system works, wiring color codes, and how and why your thermostat sends a call to the contactor in the unit for A/C for example. This product does nothing but offer a constant 24v supply to power a fancy thermostat on units too old to have that in place. The C wire that is mentioned frequently is just a common wire that gives the 24 volt power a place to return and complete the circuit. In a forced air/Nat Gas heat and A/C example, you would simply place one of the white wires from this product to the C terminal and one to the RC as the picture on the listing shows. The RC and RH terminals are the two "hot" lines in this example. RH + green runs the fan, RH + Yellow runs the compressor, RH + White runs the Heat, and RC + C powers the fancy thermostat. Your thermostat will combine inputs for you to make everything work, for example RH + Y1/G is the Call to run the AC compressor and air handler fan together to pump that chilly air goodness all over your house. Hope that saved someone a sales call because "this Chinese product dont work good". ... show more

  • Another piece of garbage
Purchased this tranformer to give power to my nest learning thermostat and as usual when you buy something from China its delivered with no instructions or very hard to understand instructions, this came with nothing so i looked it up and I saw something that resembled my thermostat and I followed the instructions which were taking the two wires from my transformer and installing them into the C port and the RC port when I turned the power back on the air conditioning unit would not shut off even with the thermostat in the off position, tried multiple steps over to se if something was loose or not properly installed , but still same problem the AC would not turn off. Had to disconnect the transformer and the Thermostat operated and the AC unit went off. this product DID NOT work for me and I would have probably got it to work if there were proper instructions for my thermostat , so now it goes into the junk box with all the other non -working gadgets. ... show more

  • Compatible With Milivolt Systems
Got yourself an In-Wall Heating Unit? Just bought a Google Nest Thermostat and it isn't compatible? This will fix the issue. The wires are so long that it really doesn't matter how much you mess up at first trimming it, just wrap it snugly around the existing wire. When you get it down and plug it into its corresponding slot on the Nest and into the socket, you're golden. Enjoy your smart home automaton. ... show more

Works fine with my GE CYNC Smart Thermostat. I followed the wiring diagram from the product pictures, I don't think it came with any instruction manual.
