How do I connect the thermostat to my home Wi-Fi network?

On your wireless device, find and connect to the network named 'NewThermostat_123456' (the number will vary), then open your web browser which should automatically direct you to the Thermostat Wi-Fi Setup page at http://192.168.1.1. From there, select your home network, enter your password, and click Connect. The thermostat message center will display 'CONNECTING...' for up to 30 seconds and then confirm a successful connection.
