Temperature Regulation Loop
This section of the database contains the registers needed to manage the temperature regulation loop but is not used by the system EBV.
Clock Functions
This section of the database contains the registers 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.
Register Address 180
Not used by the EBV system.
Register Address 181: Minutes
This database register contains the value of the minutes received during the time synchronization phase.
Register Address 182: Hours
This database register contains the value of the hours received during the time synchronization phase.
Register Address 183: Day
This database register contains the value of the day received during the time synchronization phase.
Register Address 184: Month
This database register contains the value of the month received during the time synchronization phase.
Register Address 185: Year
This database register contains the value of the year received during the time synchronization phase.
Register Address 186: Reset EEPROM Area
This database register allows to reset EEPROM area.
Writing the value to 1 will reset the memory area to the default values.
