Label wires and remove old wallplate

Use a screwdriver to disconnect wires one by one. As you disconnect each wire, wrap it with the label matching the letter on your old thermostat. (Adhesive labels are supplied in your thermostat package.)

Remove the old wallplate only after all wires are labeled. Be careful not to let loose wires fall into the wall opening.

Wrap supplied labels securely around each wire

Do not let wires fall into wall opening!

IGNORE WIRE COLORS: Use only letter designations to identify wire types.
