This register contains the value of the year received during the time synchronization phase.
Registers from address 1181 to address 1185 contain the values that store the date and time of the actuator once they have been synchronized (only necessary in the case of energy calculation).
The actuator doesn’t have a “buffer” battery so that every time it is turned-off or reset the date and time are lost, a new synchronization will therefore be required. If the date and time are not synchronized the default date/time is: 01/01/2000 00:00.
