Where does the C wire go on a thermostat?

Insert a C wire into the C terminal on your wall plate if you have one. Let us now examine the G wire. This cable should be connected to the G terminal on your new thermostat. For the Y, Y1, and Y2 wires, connect Y or Y1 to the Y terminal, and connect Y2 to the Y2 terminal. The O/B wire can be configured in a variety of ways. Typically, this wire is used as a return path for power from other parts of the system to the heater. But it can also be used to provide heat itself or act as a shut-off switch for the heater.

In conclusion, a thermostat has three terminals: C, E, and Y. The C terminal accepts a C wire from the controller, the E terminal connects to the E wire from the controller, and the Y terminal connects to the Y wire from the controller. Each terminal has two functions: one to receive power and the other to send signals. Power goes in through the C terminal and comes out through the Y terminal. Signals are sent over the E wire from the C terminal to the Y terminal.

How do you wire a second thermostat for a fan?

All you should have to do is connect the wire from the G terminal on your old thermostat to the W terminal on the new thermostat. Then connect the RH on the original thermostat to the RH on the new thermostat with a jumper wire. If you have a wire on the C terminal, you may connect it to the C on the new thermostat with a jumper. Be sure to select the correct terminal size for the wire you use for this purpose.

If you want the new thermostat to control more than one zone, you will need to install multiple thermostats. The HVAC technician will be able to help you with which type of system you will need and how many zones you will be able to control with one set of codes.

He will also be able to guide you through the wiring process and answer any questions you may have about the code required for each step.

After completing the wiring process, make sure that you test all the functions on both the old and new thermostats before you leave the house for vacation or weekend. This will ensure that there are no problems with the system after you make the change over.

How do you install a wall thermostat?

Installing a New Thermostat

  1. Turn Off Power to A/C and Furnace.
  2. Take a Picture of the Wires.
  3. Disconnect Wires from Old Thermostat.
  4. Put on the New Thermostat Mount and Connect Wires.
  5. Screw Faceplate Mount to Wall.
  6. Attach New Thermostat Face.
  7. Turn Power Back On to A/C and Furnace.
  8. Configure New Thermostat.

How do you replace a thermostat on a wall?

Re-insert any exposed cables back into the wall. Install the thermostat flat against the wall, just above the wall plate. To sit in place, slide it down until it catches the grooves (or screws) on the wall plate. Now turn it over and screw it to the wall using the provided holes.

That's it! Now when you flip the switch on your heater or air conditioner, the new thermostat will activate its own circuit and you'll be able to control the temperature from anywhere in the house with your phone or other remote.

The advantage of this method is that there are no wires behind the wall anymore. The disadvantage is that you have to drill new holes for the screws on the new thermostat. If you don't want to do that, then use heat-shrink tubing instead. It's also easy to remove if you ever need to relocate it.

Here are some other things you should know before you start working on your heater/AC:

Heaters and ACs are heavy items to move around so make sure you have help ready to give you a hand. You don't want anyone getting hurt while you're trying to save money by doing work yourself.

Make sure you understand how your heater/AC works before you start working on it. Some units require special tools to change.
