In Pronestor Display 2018, you can enable Night Time mode to reduce the energy consumption of your display devices during closed hours.
Night Time mode works for Room Displays, Reception Displays and Area Displays.
Go to the configuration for the specific Display. Go to the Visibility tab and set "Sleep start" and "Sleep end" to your preferred out-of-office hours. Once enabled, the displays will turn dark in the selected time span but you will always be able to "wake up" the display on touch if needed.
