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 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.

What are common wires?

The common wire is normally the white wire, at least in the United States, and is often called the neutral wire. It’s also called common because all circuits in the house typically have the white wires tied together, which means every circuit has that wire in common.

How do you wire a fan motor?

Quote from the video:

Where does the C wire get power from?

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.

What color is the common wire?

A simple standard electrical circuit has a black or red “hot” wire that carries power from the power source to the device (e.g., switch, fixture, outlet, appliance), a white neutral wire that carries the power back to the power source, and a green or bare copper ground wire that connects the device to the home’s

What is orange electrical wire?

Red or orange wires are often used to provide the secondary phase voltage in a 220-volt application. Always assume that a red or orange wire (in addition to the black wire, which provides the primary phase voltage) is live.

How do you know which wire is positive and negative?



If you have a wire where both sides are the same color, which is typically copper, the strand that has a grooved texture is the negative wire. Run your fingers along the wire to determine which side has the ribbing. Feel the other wire which is smooth. This is your positive wire.
