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.

    • Works well with my oil furnace and Ness thermostat

    • Solves the missing c wire - specific to the Nest thermostat, not a universal solution
Size: 1.1 x 3.03 x 3.98 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

    • Nest Power essential for Nest Thermostats!
Size: 1.1 x 3.03 x 3.98 Style: Connector
Nest digital thermostat features were not fully enabled, and frequent 'batteries low' or 'replace batteries' messages on thermostat despite new batteries. If you have an HVAC system, the Nest Power connector is essential for full controls and HVAC management by Nest Thermostat. The HVAC service technician who we had install the unit suggested this was the best solution he had seen for wire integration of a Nest thermostat. ... show more

    • Did not add a common path
Size: 1.1 x 3.03 x 3.98 Style: Connector
I recently installed a nest learning thermostat. I did not have a C wire but the nest nevertheless worked fine. I read online that it's a matter of time until getting the battery low error so I thought I'd be proactive and add a charging path for the thermostat. Installation was very simple, opened the HVAC panel, connected the R and Y thermostat wires to this power connector and the R and Y from the connector back to the HVAC board. Additionally, I connected the C wire coming from the connector to the C slot on the board. I used a multimeter to make sure that indeed is a C wire which was pretty obvious as it was coming from secondary of the 110/24 transformer. The annoying part is the nest learning will not give you any indication if the power connector is detected and working or not. This should be added considering this is from Google and not a third-party and the thermostat can get updates. So I had to check the power in the thermostat's settings. I was getting Iin=40 mA with AC OFF and Iin=20 mA when AC ON which is basically the same as having no C connection. To triple check, I then removed the connector and repurposed my G (fan) wire to C slot on the thermostat and the same C slot I used before with the connector at HVAC. Checked my thermostat settings then and I was getting Iin=200 mA which showed the C connection was actually working. Unfortunately, this isn't a feasible solution for me since my AC doesn't automatically turn the fan ON without G connection. I could not find anywhere how this connector is supposed to work but my assumption is it internally switches between R-Y path to R-C path when R-Y is not needed so the thermostat doesn't have to draw so little current from R-Y without making the AC ON or malfunctioning. However this is supposed to work, it obviously didn't for me. I see some people had luck with this item but I am still giving it one star since not only it didn't work for me, the device has no status indicator to tell if it is defective or simply not working with a certain system. They could add some small LEDs or at least they could show on the thermostat or in the app that this is detected and if it is working/not working. ... show more

    • Check your thermostat version
Size: 1.1 x 3.03 x 3.98 Style: Connector
As a product, this is similar to the other Nest products. Good quality, nicely packaged, well thought out and clear instructions, and even the quality of the supplied wire connectors was great. I recently purchased two Google Nest learning thermostats as part of a PSEG promotion, to replace old 2-wire thermostats controlling a hot water baseboard system with Taco zone valves. While the thermostats worked sorta, it was clear that without a common wire, the thermostats were unreliable. So I hoped that this Power connector would help, but after installing and following instructions, things just worked the same way as before. I then realized that the new Learning Thermostats that I had just bought were v2, and this power connector only works with v3 learning thermostats. So if you have a learning thermostat, make sure you know which version you have before buying these. In my case, things ended up in a good place because while I was doing this, I realized that the thermostat cable in my house was actually a 3 conductor cable even though only two were used (Rh and W). So I was able to create an actual C wire using the spare conductor in the existing cable, connecting one end to the C terminal on the thermostat, and the other to the #2 terminal on the Taco zone valve. I did this for both thermostats, and they both now work perfectly all the time. So the moral of this story is, before you spend money on one of these things, check your existing wiring and make sure there is not an unused conductor in your thermostat wiring that you can use to make a common wire and get the best solution for a few minutes of work. (And if none of that makes sense, hire a pro to help!) ... show more
