    14-FIRST START-UP WARNINGS BEFORE IGNITION GENERAL WARNINGS Remove all parts that may burn from the brazier and the glass (manual, various adhesive labels or any polystyrene). Check that the brazier is positioned correctly and rests properly on the base. The first ignition may not be successful as the feed screw is empty and does not always manage to load the brazier with the required amount of pellets in time to light the flame.

By pressing the button the START&STOP function is started. The icon will appear for 3”, and then go back to the previous view, where the house near the temperature turns into the icon, as a reminder that it is activated.
  • Page 19 19-START&STOP INTERVENTION DELAY (ADJUSTMENTS OF THE START&STOP TEMPERATURE HYSTERESIS) When the room temperature is reached, there is a waiting time for intervention to prevent the equipment from suddenly turning on/off as the room temperature drops/rises, for example, when a door or an external window is opened. This waiting time therefore allows you to be sure that the room temperature has actually dropped for a certain time inside the room (for example 5 minutes).

The Bluetooth connection is not deactivated but is always waiting for a connection (with devices that are already registered), so that if a paired device is within range at different times of the day, it automatically connects to the product (just like a mobile phone when entering the car).
  • Page 24 22 - WI-FI/WPS/BLUETOOTH ENABLING/DISABLING WI-FI and WPS By default, the product has Bluetooth network enabled and Wi-Fi active but not connected: this means that Wi-Fi is not visible until the product is connected to a Wi-Fi/home network.
