IDDERO HCx-KNX TOUCH PANELS – User Guide
20
The system prompts for a PIN code every time users try to access a page that requires higher
permissions than they currently have (for example, when a user that has previously entered a level 2
PIN code tries to access a page that requires level 1).
Additionally, it is possible to specify whether a valid access code is required in order to start a new
session from the home page (“Password required to start session”). In that case, when the user
touches the home page, a valid PIN (for any of the access levels defined) will be required.
Current user permissions remain in effect until the user returns to the home page, either manually or
due to system idle time (see next section).
3.10 System Inactivity and Power Saving Mode
After a certain period of inactivity (i.e., no user interaction), the system automatically returns to the
home page. Once on the home page and, again, after a certain period of inactivity, the system enters
power saving mode.
During power saving mode, the display is automatically turned off and the power consumption is
minimized, even though all system functions (such as timers, alarm monitoring, etc.) remain
operational.
Touch the screen to exit power saving mode. The system also exits power saving mode automatically
upon reception of an incoming call from the video door phone.
