Label Old Thermostat Wires - Honeywell RTH7500D Owner's Manual

Step 5. Label Old Thermostat Wires
1. As you disconnect each wire, use the enclosed wire
labels to wrap a wire label around each wire that
matches the letter designation. Do not allow the
wires to fall into the wall opening after the wires are
disconnected.
2. Remove any remaining part of the old thermostat
from the wall.

When connecting the wires to the new
thermostat, refer to the wire labels. Do not
connect wires to your new thermostat based on
the color of the wire.
