Blue wires
Blue wires are also called “C” wires because they are the Common wire. C wires are necessary for any “smart” thermostat that needs to be connected to a power source 24/7, regardless of your heat pump type.
Where does the C wire get its power?
WHAT IS A C-WIRE? A C-wire, or a common wire, runs from your low voltage heating system (24v) and carries continuous power to your thermostat. In today’s electric market, most newer heating and cooling systems have C-wires, which guarantees compatibility for the installation of all smart thermostats.
How do you put a C wire in a thermostat?
Quote from the video:
Quote from Youtube video: Run actual thermostat wire in the all and connect. It to the existing thermostat wire if you've got an extra wire or if you want to fish some new ones in the wall. Not a big deal there.
What if there is no C wire for thermostat?
You most likely have a line voltage system and none of the popular smart thermostats on the market are available to you as-is. (There is some hope with an adapter, but don’t get too excited yet.) This wiring indicates a line voltage system, and you’ll need an adapter or a smart thermostat designed for line voltage.
What is the blue wire for?
Blue & Yellow
These two colors are hot wires usually pulled in conduit for common plug-in electrical devices. Blue wires are used as travelers, usually on three- or four-way switches (controlling a light from multiple locations) or as switch legs for things such as fans or lights.
What color wire goes where on a thermostat?
This is the most typical thermostat wiring style, and it applies to systems that regulate both heat and air conditioning. The wires are typically arranged as follows: red for 24-volt hot, white for heat, yellow for cooling, green for the fan, and blue for common (although the common wire may be a different color).
Is blue a live wire?
Plug wiring colours

Can nest work without C wire?
You can install a Nest Thermostat without a C-wire by using a C-wire adapter, that mimics a traditional C-Wire without you having to wire it. If you are not a handyman, it saves a lot of money that you would otherwise have to spend on a professional installer too.
What do the colored wires on my thermostat mean?
Red – Rc – 24VAC (dedicated to cooling call) Green – G – Fan. White – W – Heat. Yellow – Y – Air conditioner.
Where do thermostat wires go?
Thermostat Wiring Tips
The W wire is connected to your heating system. If your thermostat controls your heat, you will have a white wire. The Y wire is yellow and connects to your air conditioning compressor. The G wire is green and connects to the fan.
Can I use the G wire for the C wire?
Quote from the video:
Quote from Youtube video: And we're going to remove the G wire from the G terminal. Move it over to your C as in Charlie terminal. We're going to make a jumper of a short piece of wire. And jumper between the Y and the G. And
Is C wire the same as RC wire?
The C and Rc wires are not the same. To install this thermostat you should follow the exact same wiring of the previous thermostat.
What color is common wire?
White. The “common” is the “neutral” or “ground” wire, depending on the type of circuit. In normal US residential wiring, you’ll have a black “hot” wire, a white “neutral” or “common” wire, and a green or bare “ground” wire.
Why is there a jumper between RH and RC?
In most cases, the heating and cooling system share a single transformer by leaving the jumper in the lower right corner it connects the RC and RH to power heat and cool features.
Do I use RH or RC on Nest thermostat?
The Nest Thermostat E only has an R connector, which is typically where an R wire would go. If you have separate heating and air conditioning systems, you might have separate Rh and Rc wires that come out of the wall and are connected to your system.
Where does Rh wire go on Nest thermostat?
Note: If you have an R, Rc or Rh wire, you can put it into the R connector on the Nest Thermostat. If you have a W2, Y2 or O/B wire, you can put it into the *O/B connector, if needed. Gently tug each wire to check they’re secure, and make sure each connector that has a wire stays down.
Do I use R or RC on thermostat?
If you have two wires, R or RH go into the R terminal and RC into the RC terminal. If you have more than one wire (for example, you have a wire labeled R and another wire labeled Rc), remove any jumpers between the R and Rc terminals or push the switch to open the RC terminal to insert a wire.
