The final screws for every single device the thermostat is attached to to should be marked with letters like RC, Y, G, W and R. Wrap a bit of masking tape around each wire to to make a tag together with the tape before you eliminate the wires. Mark the tape with the letter designation of the final of every wire screw using a felt-tipped pen.
Loosen the terminal screws using a screwdriver and unhook the wires in the screws. In the event the wires want to pull-back to the wall, tape them down with masking tape to to keep them.
