To which terminals are the wires of a thermostat wired?

  1. R,W,G

  2. A,B,C

  3. T,Y,Z

  4. X,Y,Z

The correct answer is: R,W,G

When wiring a thermostat, the wires are typically connected to terminals labeled R, W, and G. These correspond to the red (R), white (W), and green (G) wires. These terminals are used to connect the thermostat to the heating, cooling, and fan systems in a home. The other options listed, such as A,B,C and T,Y,Z, do not correspond to commonly used thermostat terminals and are incorrect. Option D, X,Y,Z is also incorrect as these letters do not correspond to any common thermostat wiring terminals. Therefore, the correct answer is A.
