This is not a fault. The heater has simply sensed a sudden drop in room temperature associated with a window being opened & has stopped heating the room as a result.
Close the window, or if a window was not open, check for draughts.
If the customer does not want to use Open Window, it can be disabled. Press MENU . Select "Settings"- "Adaptive" - "Open Window" - "Disable".
