Took a while to figure out how to wire it correctly. Had to Google and look at other reviews to figure it out. Comes in a box with no directions. Hard part was figuring out which R connector to use. I first tried RH and C and that didn’t work. Then tried RC and C and it worked. I disconnected what was on RH and not sure what was on that connection. I needed the transformer because the AC and heater was not providing enough power to nest thermostat. I had a professional come out for 2 hours and couldn’t get power to work. So I googled the solution and found this transformer product. Posted pictures on the setup. The white wires are from transformer. You can see in the photo nest showed no power in the battery menu VOC=0. Then when I added wires to RC and C, the VOC=27 ... show more

    • An easy solution for a complicated problem
This adapter/transformer is a time and cost saver. I used it to power my new google nest thermostat. My old thermostat is connected to two wires labelled B and W. Though there is an R wire, it was not connected. In order to replace the wire connected to my old thermostat, it is a cost and time consuming. Adding R and C wire using this adapter solved a complicated problem in a few second. Highly recommended! ... show more

    • Did not work on my Nest-e thermostat
Waste of money. Was hoping to use it as a common wire, but while it powered the thermostat it would not turn on the boiler. I had to revert the installation back to the original wiring.
