4. Using the provided stickers, label each wire according to the Wire Labels chart. (If the terminals are not labeled, contact a qualified HVAC technician.) Note: Wire colors do not always comply with standards, so wire color should be ignored. Refer to the existing terminal designation for proper identification. *If wires marked Y & C are both present, C may be a Common wire and should not be used. If you have a wire marked C, do not connect it to any terminal. This wire is used only for non-battery powered thermostats. 5. Do not let the wires slip back into the wall during disconnection. You may want to secure the wires to the wall as you disconnect them. After all wires are labeled, disconnect each wire and remove the existing wall plate. (Any unused wires should be capped with an approved electrical connector, such as electrical tape.) 12 W/BRCGY/ 0Y1 W/BRCGY/ 0Y1 installing the thermostat INSTALLING THE WALL PLATE 1.
