    Deep sleep mode Deep sleep mode is a useful feature to extend the battery lifetime. This is done by suspending normal functions of the controller, and place the it in the lowest power consumption state. The controller maintains the status and alarms it had before Deep sleep mode. When the controller wakes up, normal operations are resumed automatically.
