!CAUTION

To prevent electrical shock and/or equipment damage, disconnect electric power to system at main fuse or circuit breaker box until installation is complete.

Before removing wires from old thermostat's switching sub- base, label each wire with the terminal designation it was removed from.

1.Shut off electricity at the main fuse box until installation is complete. Ensure that electrical power is disconnected.
