Figure 63: Display page for setting the time and defining the time display format
When setting the date and time, the system clock integrated in the device is set. The system
time and system date of the embedded Linux operating system are also derived from this
system clock. The system time also controls the internal timer of the device (see page 226).
i
The device's internal system clock is designed as a real time clock (RTC) and is extremely
accurate. It is advisable to set the system clocks of all devices once a day, for example, by
a shared KNX time telegram during the night hours, so that that the timing of all devices is
synchronized even over a long period of time.
The system clock has its own energy storage. This will ensure that the clock keeps on
running interruption-free for at least 2 hours in the event of a power supply failure.
The real time clock has a calendar function. Depending on the date set, the day is
determined automatically by means of the internal calendar which is necessary for
processing the timer.
You can set the date or time by pressing your finger on the corresponding display pages of the
display area for the date or time (3) (figure 64). The display then branches to the editing mode
and displays a keyboard. You can edit the date or time directly via the keyboard (4.).
The setting is acknowledged either via the "
>
" button in the keyboard or alternatively via the
"Save
>
" button (5.) in the status line and thereby transferred to the system clock. The display
then returns to the system page.
Settings can be discarded either by pressing the "
X
" button in the keyboard or by pressing the
"
Z
Cancel" button in the status line. The display then returns to the system page without saving
the setting.
i
The following figure shows the editing mode for the date. The time is set in the same way.
The keyboard has an "am/pm" button for setting the time of day (morning / afternoon) for
the 12-hour display format. In the 24-hour format or for entering the date, this button has no
function.
