There is no "RC" on this thermostat.** A: I have a Nest E. Since it doesn't have an RH port, I just used R. So I have one wire connected to C and another to R (in addition to the existing R wire). I was able to get both wires to fit in the R terminal just fine. I'm not sure if this is officially support or correct (I'm not an electrician), but it seems to have been working fine for the last week. No issues yet, and the thermostat is now getting 200 mA (instead of the 20mA I was getting before without the C wire). My thermostat is now at 3.9V. **Q: Nest e: has an r (power) connection, no rc or rh. so i connect one adapter wire to the c, does the other go to the r? what about the existing r wire?** A: Wiring will be different for different devices. All this does is provide the constant power line. This is often the c and RC lines, but can be different. **Q: My nest thermostat uses y1, g, rc, w1, and rh. do i use c and double up the rc or rh? or something else? thanks** A: HI You only need to connect C and RC. No need to connect RH thank you **Q: Can I power this wire through the wires from my electric outlet and run it through the wall without having the wires show on the outside?** A: You would need to plug the transformer into the outlet, then if you can run the wires inside the wall so they are hidden that would work fine. But that isn't always that easy to do, especially if it needs to be a long wire run. I plugged mine in the mechanical room & connected it to an unused thermostat wire that ran to the thermostat in another room. My original system only used 2 wires, but was wired with a 6 wire cable. ## Frequently Bought Together - 24 Volt Power Adapter/Transformer,C-Wire Adapter Thermostat，Compatible with All Versions of Ring Doorbell and Thermostat for Ecobee,Sensi and Honeywell(25Ft Cable) - Amazon Smart Thermostat – Save money and energy - Works with Alexa and Ring - C-wire required --- ## 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.tn/products/97092767-24-volt-power-adapter-transformer-c-wire-adapter-thermostat-compatible](https://www.desertcart.tn/products/97092767-24-volt-power-adapter-transformer-c-wire-adapter-thermostat-compatible) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-16*
