"It is not possible to physically turn off your thermostat without removing the power directly from your electrical panel. However, you can turn the thermostat OFF (antifreeze mode if it is working in heating, thermal protection mode if it is working in cooling) via the Home + Control app: 1) To turn OFF a single Smarther: go to the Home + Control room where the product is located and disable it by clicking on the cursor next to the product name 2) To turn OFF all the Smarthers in your home: on the app homepage, click on the scheduling banner and select OFF from the menu that appears. Here you can select whether to leave the thermostats OFF forever or until a certain end date."
