5. Setup: Network Connection

The Beok BOT-R15W-Zigbee thermostat requires a Zigbee wireless mesh network and a compatible smart gateway (e.g., Tuya Zigbee Bridge WLN-03-X, sold separately) for app control and smart home integration.

5.1. Thermostat Network Configuration

1. Ensure the thermostat is powered on.
2. Press and hold the 'O' key for 5 seconds.
3. An icon will flash in the upper left corner of the screen, indicating that the thermostat has entered the network distribution state.

5.2. Smart Gateway Network Configuration (if not already set up)

1. Power on your Smart Gateway.
2. Press and hold the reset button on the gateway for 5 seconds.
3. When the network connection indicator light on the gateway flashes, open the 'Smart Life' or 'Tuya Smart' App on your mobile phone.
4. Follow the in-app instructions to complete the network connection for the gateway.
5. Once the network connection indicator light on the gateway is constantly on, the gateway has been successfully connected to the network. (If your gateway is already added to the app, you can skip this step).
6. In the 'Smart Life' or 'Tuya Smart' App, add the thermostat as a new device and follow the pairing instructions.
