Just pick one wire to put on each screw on doorbell. **Q: Have you left the jumper wire between R and RC?** A: No, you're not supposed to leave that jumper in there! I don't know how bad for the system it is, but if you now have both R and Rc you don't need that jumper connecting the two. It's only there as an improvisation when you have only one of the R terminals filled. I would remove that jumper on both ends of your system as it wouldn't be necessary now. **Q: Wire material?** A: I believe it's standard material, nothing special. **Q: I have a google nest thermostat.. my only have cable connection for y g c r w ob where should connect the cable c i see that included two ends** A: Not sure if this is helpful but I have a old traditional wall heater and this is my connection which works great. W1, W2, C and Rh.. the traditional wires go into w1 and w2 and doesn't matter which of the adaptor wire goes into C or Rh ## Frequently Bought Together - 24 Volt Transformer, C Wire Adapter for Nest Honeywell Ecobee and Sensi Thermostat, Doorbell Transformer Compatible with Wyze Video Doorbell - Sensi Smart Thermostat, 100 Years Of Expertise, Wi-Fi, Data Privacy, Programmable, Easy DIY Install, Works With Alexa, Energy Star Certified, Mobile App, ST55 - Sensi Lite Smart Thermostat, Data Privacy, Programmable, Wi-Fi, Easy DIY, Works With Alexa, Energy Star Certified, ST25, Most Systems C-Wire Not Required, Except On Heat/Cool Only and Heat Pump System --- ## 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.jp/products/141182788-24-volt-transformer-c-wire-adapter-for-nest-honeywell-ecobee](https://www.desertcart.jp/products/141182788-24-volt-transformer-c-wire-adapter-for-nest-honeywell-ecobee) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-21*
