After you have removed and labeled all wires you can unscrew, remove the old thermostat wall plate and mount the new thermostat's wall plate. If we recommend placing a wire in a terminal, do not move it to another terminal if we address it later in the guide. You will typically have one or two out of those three. If you just have one wire, regardless if it's labeled RC, it will go into the R terminal, and the jumper connecting terminals R and RC will be in place.
Some thermostats have a jumper switch, some have a metal staple, others may have a plug, and the jumper may also just be a wire connecting the two terminals. If you have more than one wire you have a wire labeled R, and another wire labeled Rc for example you can remove any jumpers between the R and Rc terminals, or push the switch to open the RC terminal so you can insert a wire.
Next, let's talk about the C, or common wire. If you have a Trane model thermostat, and have a wire labeled X or B refer to your thermostat manual. In some cases, one of those wires may be your common. If you have a C wire, place it into the C terminal on your wall plate.
