1. Remove the back cover.
2. Insert the 2 AA batteries respecting the polarity.
3. Now, find a socket close to the place where your THERMOSTAT will be installed and connect the Gateway.
4. Enter your home's 2.4Ghz WiFi network (5Ghz networks not supported). It will show a percentage, when it reaches 100% the device will have been added successfully.
5. With the Gateway paired, let's pair the VESTA THERMOSTAT. With the screen VESTA THERMOSTAT on, press and hold the ON button until the display only shows the connection icon in the upper right corner. When you see it, press the up arrow and the icon will start flashing quickly.
6. Now go to "Add device" again in the app and the THERMOSTAT will show up automatically. You just need to finish the process to start using it.
7. Access the device control panel to view the different options.
