RTC code (R01~R1F, total 31 group)
Example 1: preset second < 30s
※ The current time will return to 8:00:00 when it achieves 8:00:20 at first time, and RTC contact, R01, will turn ON,
then it does not turn OFF until the present time achieves 8:00:20 again. Then time keeps going. So, this means that
RTC status bit is ON for 21 seconds.
Example 2: preset second >= 30s
