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).
What is the blue wire on a Rheem heat pump?
This wire connects to the outside heat pump condenser where the reversing valve is located. If you have any other manufacturer other than Rheem or Ruud you will be utilizing the orange O wire for the reversing valve; Rheem and Ruud usually utilize the blue B wire for the reversing valve.

Does my heat pump use O or B wire?
On many other thermostats, the O wire is typically connected to a terminal marked W on one side and O or O/B on the other side; the W is for use with a conventional system (furnace) while O/B is for use with a heat pump.
Does Rheem use O or B?
Most commonly, O/B is energized in Cooling (O on cool). For Rheem or Ruud brand heat pumps, the O/B must energize on heating (B on Heat).
