If there is no hidden C-wire, you can use a G-wire instead. However, you will not be able to use your fan independently when the heating or cooling isn’t running. Also, many HVAC systems are incompatible with this solution, including: HVAC systems using electric heat.

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.

Does C wire have voltage?

What Is a C Wire? The C wire, a.k.a. the “common wire”, allows a constant flow of 24 VAC (volts AC) power to a smart thermostat. However, the C wire doesn’t provide the actual source of power to the thermostat. The wires that provide the source of power are the R wires (or hot wires).

Do battery powered thermostats use C wire?

No necessarily. Many thermostats, including some Honeywell thermostats use batteries as a backup. I just replaced 2 relatively new Honeywells with these and they used AA batteries but there was a “C” wire, too. You really have to take the existing thermostat off of the wall to see if there is a “C” wire available.

How do you connect C wire to HVAC?

What color is the C wire?

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.

Do I need the C wire on a thermostat?

Yes, you should install a C-wire if you are upgrading your thermostat. Nearly all modern thermostats, smart or not, require a power source, and that doesn’t look likely to change any time soon.

Can you install Nest Thermostat without C wire?

What is the Pek terminal on ecobee?



The ecobee PEK provides the constant electrical power needed to run the display and connect to WiFi in systems without a C-Wire. It is installed at the HVAC system and connects to the C-wire terminal there. But, since the wires running to your thermostat don’t have a C-wire, it instead uses the R-Wire.
