Do not disconnect wires from the old thermostat until you
label all the wires according to this manual.
2.1.1 After turning off power to your heating & cooling system,
expose wallplate with wires and wire terminals. The required
steps vary depending on your old thermostat type.

installation process is complete.
✔ No two wires can have the same label.
2.2.1 Note you may see two types of wiring in the old thermostat:
1. Wires leading from the wall to a
terminal on the thermostat
2. Wires connecting one terminal to
another (jumper wire).
