How do I perform the initial setup of the TC300B thermostat?

The thermostat will power up automatically after mounting. You will navigate through guided setup screens including: Device Name, Network Connection, Temperature Units, Date & Time, Equipment Type, System Switch, Setpoints, and Installer Passcode. Follow the on-screen prompts and tap the arrows to proceed through each step. The setup process takes approximately 35 seconds to return to home screen if no interaction occurs.
