The Smart Thermostat is not available as a Zone Controller when it’s been installed as a Wireless Temperature Sensor.
As a Wireless Temperature Sensor, the Smart Thermostat only measures the temperature for a room in your home. It cannot be a Zone Controller as it’s not wired to your heating system and therefore can’t directly control your heating.
However, the Zone Controller feature isn’t relevant for all homes. You can find examples of Zone Controller setups in this article.
Tip: If you’re using your Smart Thermostat wirelessly together with a tado° Wireless Receiver/Extension Kit that will be wired into your heating system, make sure to select the tado° Wireless Receiver/Extension Kit as the Zone Controller, not the Wireless Smart Thermostat.
Making the Smart Thermostat a Zone Controller
If you accidentally configured your Smart Thermostat as a Wireless Temperature Sensor but it’s actually wired, you can reconfigure your device.
To configure your Smart Thermostat correctly as Zone Controller, please follow these steps in the tado° app:
Go to Settings > Rooms & Devices and
Select the Smart Thermostat that should be a Zone Controller.
Go to Installation Instructions and select Replace existing thermostat and follow the instructions on the screen.
By selecting the thermostat that is replaced with the tado° Smart Thermostat, the configuration of the Smart Thermostat will automatically be updated to Zone Controller.
