2. After enabling Wi-Fi setup mode, view the list of available Wi-Fi networks on your wireless device – tablet, laptop or smartphone – and select the network called “NewThermostat_123456” (the number will vary.) Please note that this action will disconnect your mobile device from your local Wi-Fi network and connect it to the thermostat. This step is required. After joining, if you are asked to specify a home, public or office network, select “Home Network.”

3. After joining the network, open your web browser to access the Thermostat Wi-Fi Setup page, where you can connect your thermostat to the Wi-Fi network. The browser of your mobile device should automatically direct you to the correct page; if it doesn’t, type the following address in your web browser:

4. In the new page, find the name of your home network and select it. Some routers have enhanced features such as guest networks; use your home network. Click CONNECT to join the Wi-Fi network. The message "Wait" will be displayed on the screen of the thermostat, and the process should be completed after a short waiting period. Please note that if your network is protected by a password, you will need to insert this password to connect your thermostat.
