Does C wire have voltage?
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).
Is the C wire a ground?
No way! A “return” is not the same thing as a “ground”. In certain situations it is, but not here. The C wire (together with “the other half of the circuit”) forms a circuit through the secondary of the 24V transformer.
Is RC the same as C wire?
Hi there! The C and Rc wires are not the same. To install this thermostat you should follow the exact same wiring of the previous thermostat.
Can I jump R to C wire?
C is a common neutral wire. You can’t jump it from Rh as that is a 24v wire. You need a third wire, C, to return to the unit and hook to the common side of the transformer. For ease of thought, think of R as “hot” and C as “ground”.

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.
Can I install ecobee without C wire?

How many thermostat wires do I need?
The most basic thermostat has 2 wires; usually a red and a white wire. Two wire thermostat wiring is used for furnaces only and usually doesn’t need a “C” or “Common” wire. That’s why we only need two wires: Red wire for power (24h).
