Rtc (Real Time Clock) - LU-VE Emeritus LU1W Manual De Usuario

The LU1W controller is equipped with an internal clock for executing scheduled tasks. You can change the date and
time settings in the RTC menu.
Attention: LU1W controller does not automatically switch from solar time to daylight saving time (and vice
versa).
The clock format is as follows: DD/MM/AAAA HH: MM: SS
When you enter the RTC menu, press ENTER to change the current date and time settings: UP and DOWN keys can
change the value of each field; use the LEFT and RIGHT keys or the ENTER key to move among the different fields;
press ENTER with the cursor on the Seconds field to confirm the changes or ESC to cancel.
You can get an alarm in case of RTC failure, enabling it by PA07 parameter. The RTC failure basically implies that the
scheduled activities are not executed.
