What is energy-saving mode and how does it work?

Energy-saving mode, which defaults to OFF, causes all lights except the smart sensor light to turn off and stops heating and cooling functions when the sensor detects less than 0.5 Lux for more than 3 minutes. The machine will exit energy-saving mode immediately if any button is touched, or if the sensor detects light intensity above 0.5 Lux for more than 30 seconds. Energy-saving mode can be turned on or off through the system settings menu. (Page 12)
