In order the change the Airzone system's operating mode, you must access the installation's master thermostat and press the icon located on the top left-hand corner.

You can consult the behavior of each mode at the following link: Airzone operating modes.

If you press on the icon but nothing happens (no selection menu opens), check whether the thermostat is set up as the master thermostat or whether the installation's master thermostat is in another zone. For further information on the installation's master thermostat, see the following link: Which is my installation's master thermostat?

If you are sure that the thermostat you are trying to access is the master thermostat, check whether it has been set up in Basic mode. You can check this at the following link: Basic mode/Advanced mode.
