3.6  Using energy-saving functions 
3.6.1  Application 
The energy required for display backlighting, up to 40%, makes up a large part of the total 
power consumption of an HMI device. To reduce energy consumption, the Comfort HMI 
devices come equipped with LED backlighting. You can infinitely dim the display or turn it off 
completely. You will see energy savings of up to 40% this way.  
You can set the display brightness as soon as you configure the HMI device in the Control 
Panel.  
 
The energy-saving functions of the Comfort HMI device lower the operating costs during 
operation while increasing the display service life.  
3.6.2  Configuring the energy-saving function 
Introduction 
You have the following options to use the energy-saving functions of the HMI device: 
●  Activate the "Blank Screen" screen saver. 
●  Control the display brightness using the system function. 
The listed options do not preclude each other. This way you can develop an intelligent 
energy-saving concept in which the operator reduces the brightness as required, for 
example. In case of long periods of inactivity, the display can be switched off automatically 
after a certain period of time.
