G-W-C-Y-R(jumped->)-Rc Plugging in the new unit, I get no power. The Nest Thermostat is physically detecting a wire in the AUX/W2 connector. A common wire (C-Wire) provides Wi-Fi thermostats continuous power by connecting it to a heating and cooling system (e.g. This wire isn’t always hot, though you also can’t make any assumptions about whether there’s power on the wire or not at any given point in … Getting 25V from G to R/Rc. C-Wires are required on most Honeywell Wi-Fi thermostats, with the exception of the Smart Round Thermostat (formerly known as the Lyric Round). If you do not have a common wire, the kit will provide the power needed to … A "C" wire does not supply power it is used as a return wire (a grounded or neutral conductor). So I'm pretty sure I'm getting enough voltage on the common wire. In short, Wi-Fi thermostats need more power to run that always-on Wi-Fi connection. Common wire (“C” wire) needed. There are a lot of reasons that you could lose power but the most common reason is that at some point when you were installing the thermostat a live powered wire touched one of the other wires and shorted out the system when you had the power … It's important to note that I was reading a solid 24 v on the R wire at this point. Typically, the wires that provide the power (often called the “hot” wires) are labeled R c (cooling) and R h (heating). With a C wire powering your thermostat you won't need to worry about the batteries dying and you can set the light on your thermostat to be always on to act as a nightlight. Check for voltage at the wire connection terminals on the side of the receptacle. Remove the receptacle cover from the outlet without power. First, you have to TURN OFF the furnace.
