Description

Nest thermostats are designed to work without a C wire in most homes. But some systems may require a C wire for consistent power to your Nest thermostat. The Nest Power Connector is an affordable C-wire substitute for homes that don't have one. It doesn't require any new thermostat wiring. And with simple instructions you can even install it yourself. If something is wrong with your Nest Thermostat, Google will alert you on-device, through mobile app alerts, and over email.

  • Solves the missing c wire - specific to the Nest thermostat, not a universal solution
Style: Connector
Installed a Nest thermostat on my daughter’s condo and found out she only had two wires, red and white with no possibility of running a real C wire due to plaster walls. Confirmed that the furnace had a C wire (critical) and then ordered this dongle. My application was a heat only furnace so the wiring was fairly simple. I strongly recommend that you get three of the wagu type snap-on UL approved wiring connectors unless you have screw terminations to attach to. There are two of the snap on connectors in the box but you will need three more for the furnace side . Trust me - have the connectors handy and installing this device is easy, I tried to use twist on wire nuts but the nuts would no stay on. You need to “tell” the nest thermostat that this adapter was installed during the programming phase on your phone or tablet. Do that slowly because if you miss the check box that says this device was installed the thermostat will not work and the only way to fix it is to delete the thermostat and install it as a new device. Note - This device is specifically designed for the nest thermostat. It will not work as a workaround to add a missing C wire to other thermostat brands. ... show more

  • Super easy to install if you're comfortable turning off the power and opening your HVAC system.
Style: Connector
I moved recently and my Nest Learning Thermostat 3rd Generation was having problems where my fan was always running. I reinstalled the old thermostat and it stopped. I found online that my system wasn't supplying the Nest with enough power so I test it by moving one wire to a C wire and the fan issue stopped. I found this and ordered it once I knew for sure that was the problem. All my issues were fixes by this little Connector. The Nest gets enough power and is working perfectly! I'm comfortable turning the power off to my HVAC unit and pulling the emergency braker to make sure there is no power in the system before removing the panel on the unit. It was very easy to install once it was open. If you're not comfortable doing that, I would pay a professional to do it. ... show more

  • Worked for 2-Stage HVAC System
Style: Connector
If you've installed a Next Thermostat then you know that you need a dedicated 'C' wire so that the thermostat will receive a continual source of power to keep its batteries charged. Well, we have a 2-Stage HVAC system which does NOT have a dedicated C wire to the thermostat. I looked into pulling a new wire bundle from the control board on the air handler to the thermostat - that wasn't going to work easily. So, I bought this Nest Power Connector that you wire in so that you don't need a C wire. I wasn't able to wire it on my own. None of the instructions for this matched up to the low voltage wiring that we have running from the air handler to the thermostat. I had to hire a pro. I hired someone after talking to several HVAC specialists on the phone and finally found someone that had experience with the Nest Power Supply and Nest Thermostats. The HVAC Tech got this working for me. It works great once he got all the wiring figured out. ... show more

  • Didn't work, had to install C wire
Style: Connector
Something is wrong with the Nest Power Connector's internal components, as it tries to deliver power. I'm not sure how it's supposed to work (some kind of switch?), but it does not do the same job as a dedicated C-wire. To preface, we have a baseboard radiator system with an oil furnace and a separate AC system with air handlers. Some thermostats in our house are heat only, others both AC and heat. I installed two Nest Power Connectors, one on a Nest Learning Thermostat 3rd gen and one on a Nest Thermostat. Installation was a breeze. The 3rd gen had previously been using the workaround with a G (fan) wire as a C wire with no power issues. The Nest Thermostat was newly installed. After installation, the Power Connector at the air handler for the Nest Learning Thermostat (heat and ac controller), the unit started having low power issues within 24h (screen not turning on, disconnecting from the temp sensor, wifi disconnecting). Same issue with the Nest Thermostat in the basement (heat only) with the power connector at the HVAC (a Taco 6 zone switch relay board), with power issue error messages showing up on the screen and being emailed within a week. I double checked all the connections with a multimeter, R to W and R to C both had ~27 V, and the Nest itself read enough power coming in. Unfortunately, I had to remove the devices and run a dedicated C wire (not an easy process in our house). Since installation of the C wire, the Nest Learning Thermostat has been working excellently with no issues, indicating that the Power Connector does not do its job as a replacement for an actual C wire. (The other Nest Thermostat still will not work as after a week it had another power issue, and Google Nest support did issue me a replacement device. So it's hard to judge what caused its failure.) ... show more
