First, ensure you have followed the steps correctly:
- Open a Zigbee connection to your current hub by following the instructions provided by your Home Automation (HA) system provider.
- Once this connection is open, pull the Zen Thermostat display off the wall and press the “Network” button on the rear of the display five times. You should see the network icon flashing on the front of the display; this will indicate that your Zen Thermostat is attempting to connect to a network.
- Once connected, the network icon will stop flashing and stay illuminated.
